GETTING STARTED
Battery
Installation
The GPS 12 MAP operates on 4 AA batteries,
which are installed a the base of the unit. These
batteries provide up to 36 hours of use in
“Power Saver” mode.
To install the batteries:
1. Remove the battery cover by turning the D-ring at
the bottom of the unit 1/4 turn counter-clockwise.
2. Insert the batteries into position. Use only new
batteries. Do not mix battery types (i.e., alkaline,
NiCad, Lithium). The battery pole that you can still
see should match the symbol (+ or -) marked on the
case.
3. Replace and secure the battery cover by turning the
D-ring 1/4 turn clockwise.
Battery life varies due to a variety of factors,
including temperature and backlighting. You
may find that lithium batteries provide longer
life in colder conditions.
WARNING: Be certain that the batteries are
installed correctly by observing the polarity
markings on the bottom of the unit. An improperly installed battery (reversed polarity) can
rupture, leaking the contents of the battery into
the battery compartment.
To install the carrying
lanyard, place the loop
at the end of the lanyard
through the D-ring on the
battery cover, route the
lanyard back through the
loop and pull tight.
If using rechargeable
NiCad or Lithium batteries, use proper methods
of disposal of used batteries. Many states and
cities require environmentally sound collection
and recycling of these
battery types.

The ROCKER Key controls the movement

The Global Positioning System (GPS) is a
system of 24 satellites which circle the earth
twice a day in a very precise orbit and transmit
information to earth. The GPS 12 MAP must
continuously “see” at least three of these
satellites to calculate your position and track
your movement. At times, additional satellites
may be needed to determine a position.
By using an almanac (a timetable of satellite
numbers and their orbits) stored in the receiver’s
memory, the GPS 12 MAP can determine the
distance and position of any GPS satellite and use
this information to compute your position.
Your GPS receiver can only see satellites above
the horizon, so it needs to know what satellites to
look for. To use this almanac data, your GPS needs
to be told its general location (“initialized”) or
given the opportunity to find itself.
Initialization is necessary under these conditions:
• The first time you use your receiver.
• After the receiver has been moved over
500 miles from the last time you used it.
• If the receiver’s memory has been cleared
and all internally stored data has been lost.
Because the GPS 12 MAP relies on satellite signals
to provide you with navigation guidance, the GPS
receiver’s view of the sky will generally determine
how fast you get a position fix—or if you get a fix at
all. GPS signals do not travel through rocks,
buildings, people, metal, or heavy tree cover, so keep
a clear view of the sky for best performance.
Once the GPS 12 MAP has calculated a position
fix, you’ll have anywhere from five to twelve
satellites in view. The receiver will select the
satellites in view to update your position. If some
of the satellites get blocked or “shaded,” the
receiver uses an alternate satellite to maintain the
position fix. A GPS receiver needs four satellites to
provide a three-dimensional (3D) fix, however, it
can maintain a two-dimensional (2D) fix with
only three satellites. A three-dimensional fix
means the unit knows its latitude, longitude, and
altitude, a two-dimensional fix means the unit
knows only its latitude and longitude.
GETTING STARTED
What is GPS?
When new (or if a position cannot be determined after 5 minutes),
the GPS 12 MAP will
prompt you to initialize
the receiver. The unit
needs a starting position
to determine which satellites are in view.
Check the Satellite Status Page for ‘2D Navigation’ or ‘3D Navigation’
to verify a position fix.
3
GETTING STARTED
Initialization
Initializing Your GPS 12 MAP
To initialize the GPS 12 MAP, take the
receiver outside and find an open area where
the antenna has a clear view of the sky. You may
either hold the receiver at a comfortable height
with the antenna pointing up, or mount the
receiver on the dash of a vehicle (Appendix B)
or on a bike. (Likewise, when you use your GPS
12 MAP in a vehicle, make sure the antenna is
pointing up.)
To turn the GPS 12 MAP on, press and
hold the red power key.
The Welcome Page is
displayed when the GPS
12 MAP is first turned
on. During this time the
receiver is conducting a
self test.
The Welcome Page will be displayed while
the unit conducts a self test. Once testing is
complete, the Welcome Page will be replaced by
a warning page, then by the Satellite Status
Page. A message will inform you to “select
initialization method”. (If the initialization
prompt has not automatically appeared, press
MENU and highlight ‘Initialize Position’.)
To initialize your unit:
1. Press ENTER to acknowledge the message and
see a list of initialization options.
2. Use the rocker keypad to highlight ‘Use Map’, and
press ENTER.
3. Use the rocker keypad to point the map cursor to
your approximate location (within 250 miles). You
may also wish to use the IN and OUT zoom keys
to make it easier to identify your approximate
position.
4. Press ENTER to select the position and begin
searching for satellites.
To initialize the GPS 12
MAP, designate your approximate location on
the map display. Use the
rocker keypad and IN/
OUT keys to position the
cursor on the map.
4
This usually provides a position fix in 1
minute. You’ll know you have a fix when the
unit automatically transitions from the Satellite
Page to the Map Page. Your receiver is now
ready to use!
To turn the unit off:
1. Press and hold the red power key for 1 second.
Troubleshooting
If you have trouble initializing or getting a
position fix, check the following:
Does the receiver have a clear view of the
sky?
If there are large buildings or mountains, or
if there is heavy tree cover, the receiver may not
be receiving enough satellite signals to calculate
a fix. Also, if you’re using the GPS 12 MAP on a
car dash, make sure the unit is placed so that it
has the clearest possible view of the sky. Your
GPS will only be able to detect satellites that it
can “see” through your vehicle’s windshield.
Depending on the slope of your dash or the
overall surface area of the window, it may be
necessary to mount an external antenna on your
vehicle’s roof or trunk in order to give the unit a
better view of the sky. (Contact your local
GARMIN dealer and inquire about the GA 27
low-profile remote antenna, part number 01010052-03.)
Have you selected the right area when
initializing?
GETTING STARTED
Initialization
Once the GPS 12 MAP
has a position fix, it will
automatically transition
from the Satellite Status
Page to the Map Page.
Check for the correct approximate position
on the Map Page. Press PAGE until the Map
Page appears, or reselect your approximate
location to restart the initialization.
Have you moved more than 500 miles from
the last calculated position with the
receiver off?
Reinitialize the receiver by selecting your
approximate position on the map, or select
‘AutoLocate’ from the Satellite Status Page
options (see page 27).
To turn the GPS 12 MAP back on, press and
hold the red power key.
5
GETTING STARTED
Main Page
Sequence
The signal strength bars
give you an indication of
what satellites are visible
to the receiver, whether
or not they’re being used
to calculate a position fix,
and the signal quality.
6
If satellite reception is lost,
or an insufficient number
of satellites are available,
you will be alerted with a
‘Poor Coverage’ receiver
status and message.
The GPS 12 MAP features six main pages
which are linked together in a chain. You can
quickly scroll through the pages in either
direction using the PAGE or QUIT keys. Let’s
briefly tour each of these pages in order to give
you some insight into how they help you
navigate. We’ll go over all of them in more
detail in the reference section.
Let’s start with the Satellite Status Page,
which is the page you’ll view while your unit is
getting a position fix. If you’re not already on
this page, press PAGE or QUIT until it appears.
The Satellite Status Page shows you status
information that helps you understand what the
receiver is doing at any given time, and it’s a
page that you’ll want to occasionally refer back
to as you use your unit. It features a sky view of
available satellites, corresponding signal
strength bars, the status of your current
position fix (acquiring, 2D, 3D, etc.), and your
estimated position error (EPE). You can also tell
how much battery power is remaining, and you
can adjust the screen contrast/backlighting by
pressing the rocker keypad.
Satellites are indicated on the sky view and
the signal strength bars by their corresponding
number, from 01 through 32. The sky view
shows where it is looking in the sky for each
satellite, by indicating the direction and
elevation (angle above the horizon). The signal
strength bars depict the
relative strength of the
signal from each satellite
being received. The taller
the bar, the stronger the
signal.

The Position Page shows you where you are,
what direction you’re heading, and how fast
you’re going—and it’s the page you’ll want to
use when you don’t have a destination selected.
A graphic compass display at the top of the
page shows your direction of travel (track)
while you’re moving, while six user-selectable
data fields below display your current speed,
average speed, trip odometer, trip timer, and
sunrise/sunset times at your current position.
“User-selectable” means you can change them to
display other information. We’ll cover these
fields more in the reference section.
Below the user-selectable data fields are
additional data fields to display your current
position, along with current time and date. The
current position readout can be in latitude/
longitude, UTM/UPS, Maidenhead or one of
several regional grids. Current time and date
can be in local time or UTC (Coordinated

Map Page
The Map Page shows your movement using a
real-time track log (an electronic breadcrumb
trail that appears directly on the map as you’re
traveling), and your present position as a
pointer icon in the center of the map. The Map
Page also shows any nearby lakes, rivers,
highways and towns. Use the zoom keys (IN
and OUT) to adjust the map to the desired
scale.
To change the map scale:
1. Press the IN zoom key to select a smaller scale
and more detail for a smaller area.
2. Press the OUT zoom key to select a larger scale
and display a larger area.
With the map oriented
to ‘track up’, the pointer
always points up and the
map rotates to your current direction of travel
(track). Note the north
indicator on the map.
The map can be oriented with the top of the
page always pointing north, oriented along your
desired course, or it can automatically rotate to
keep your current direction of travel (track) at
the top of the screen. The default setting is
‘North Up’, which keeps the top of the page
always pointing north.
Nearby waypoints are depicted on the map
with any one of over 50 different symbols, with
the waypoint name shown directly above the
symbol. We’ll cover more about the GPS 12
MAP’s waypoint features and the Map Page in
the reference section of this manual.

You can also select a fullscreen map from the
Map Page Options. See
page 35.

Present Position
Map Page
The GPS 12 MAP features two different
navigation pages: Compass and Highway. The
Compass Page is first. This page provides
graphic steering guidance to a destination
waypoint, with an emphasis on the bearing to
your destination and current direction of travel.
(The Highway Page places greater emphasis on
the straight-line desired course and the distance
and direction you are off course.) The middle of
the page features a rotating ‘compass ring’ that
shows your course over ground (track) while
you’re moving, and a bearing pointer that
indicates the direction of the destination
(bearing) relative to the course over ground.
The compass ring and pointer arrow work
independently to show—at a glance—the
direction of your movement and the direction
to your destination. For instance, if the arrow
points up, you are going directly to the
waypoint. If the arrow points any direction
other than up, turn toward the arrow until it
points up—then continue in that direction.
The current speed and distance to the
destination waypoint as well as the time to the
destination waypoint and the current time are
displayed at the top of the screen. This page
provides better steering guidance than the
Highway Page when travelling at slower speeds
and/or when making frequent directional
changes.

of the highway.
The GPS 12 MAP’s Highway Page also
provides graphic steering guidance to a destination waypoint. As you head toward your
destination, the middle of the screen provides
visual guidance to your waypoint on a moving
graphic “highway.” Your present position is at
the bottom center of the highway display. The
line down the middle of the highway represents
your desired course. As you navigate toward a
waypoint, the highway will actually move—
indicating the direction you’re off course. To
stay on course, simply move toward the center
of the highway.
The top of the page indicates speed and
distance to your destination (or the next
waypoint in a route), along with a track
compass showing current direction of travel.
Next to the speed reading is the time required
to reach your destination (or the next waypoint
in a route), in hours/minutes or minutes/
seconds. The pointer also shows the bearing to
your destination, relative to your current track.
If the pointer points straight ahead, you’re
heading directly to your destination!
Use the Highway Page as your primary
navigation page (in lieu of the Compass Page)
when your main concern is following a defined
course.

The GPS 12 MAP’s Main Menu provides
access to additional pages (submenus) that are
used to create or edit waypoints, create routes,
list nearby waypoints, review trip information
and timers or make changes to system settings.
These six pages are divided into categories by
function. The waypoint and route management
features of the Main Menu are described in
more detail in the Reference section of this
manual. Let’s take a look at the Main Menu and
one of its submenu items.

GETTING STARTED
Marking
Waypoint
Positions
GPS is really about marking and going to
places called ‘waypoints’. Before we can use the
GPS 12 MAP to guide us somewhere, we have
to mark a position as a waypoint. Your GPS 12
MAP can hold up to 500 waypoints.
To mark your present position:
1. Press and hold the ENTER/MARK key. The Mark
Waypoint Page will appear, with a default threedigit name for the new waypoint in the top
portion of the page.
To rename the waypoint:
1. Use the keypad to highlight the name field, and
press ENTER.
2. Enter the new waypoint name using the rocker
keypad, and press ENTER.
Each waypoint may also be assigned a
custom waypoint symbol for easy waypoint
recognition on the Map Page.
Each waypoint stored in
memory is identified by
a unique name, up to six
characters long (letters
and/or numbers).
To change the waypoint symbol:
1. Highlight the waypoint symbol field (immediately
to the left of the waypoint name field) and press
ENTER.
2. Select the desired symbol, and press ENTER.
3. Move the cursor to the ‘DONE?’ prompt, and press
ENTER.
The Mark Position Page will be replaced with
the page displayed before you pressed ENTER/
MARK to mark your position. The new
waypoint is now stored in the GPS 12 MAP’s
memory.
Each waypoint may also
be assigned a custom
waypoint symbol, making it easy to identify the
waypoint on the Map
Page.
12
Once you’ve stored a waypoint in memory,
you can use the GPS 12 MAP to guide you to it
by using the GOTO feature. A GOTO is really
nothing more than a straight-line course from
your present position to the destination you’ve
selected. A GOTO can be performed several
ways: by specifying the destination from the
GOTO Page, graphically from the map display
or by highlighting the waypoint name on any
page (such as the Nearest Waypoints List).
To select a GOTO destination from the
GOTO Page:
GETTING STARTED
Going to a
Waypoint
1. Press GOTO. This captures your current position
as the starting point for your trip.
2. Highlight the ‘All’ tab, using the rocker keypad, to
list all waypoints currently stored in memory.
3. Highlight the desired waypoint, using the rocker
keypad, and press ENTER.
To select a GOTO destination from the
Map Page:
1. With the Map Page displayed, use the rocker
keypad to place the cursor over the desired
destination waypoint. (If no waypoint exists at the
destination location, the GPS 12 MAP will
automatically create one, named ‘MAP’ in the step
below.)
To select a destination
from all waypoints stored
in memory, highlight the
‘All’ tab, than select the
desired waypoint and
press ENTER.
2. Press GOTO, and then ENTER to navigate to the
selected location.
To GOTO a listed waypoint on the
Nearest Waypoints List, Nearest Cities
List or Nearest Exits List:
1. With the Nearest Waypoints List, Nearest Cities
List, or Nearest Exits List displayed (see pages 49
and 50), use the rocker keypad to highlight the
desired waypoint or city.
2. Press GOTO, and then ENTER to navigate to the
selected location.
Once the GOTO destination is selected, use
the Map Page, Compass Page and/or Highway
Page to keep track of your progress as you head
toward your destination.
To GOTO one of the
listed ‘Nearest’ cities,
highlight the desired city,
press GOTO and then
ENTER. A new waypoint
will be created using the
city name.
13
GETTING STARTED
Cancel GOTO/
Active Route
To cancel the current GOTO destination,
simply select another destination. If no
destination is currently desired, or you want to
resume a previously selected route, the GOTO
operation may be cancelled from the GOTO
Options Page.
To cancel the current GOTO destination:
1. Press GOTO.
2. Press MENU.
3. Highlight ‘Cancel GOTO’ and press ENTER.
Active Route Page
To cancel the current
GOTO destination, select
‘Cancel GOTO’ from the
GOTO Options Page.
The last of the six main pages is the Active
Route Page. This page shows the Active
waypoint or each waypoint of a route, with
waypoint name and the course along each leg
(segment) of the route. When using a route, the
current destination is marked with an arrow on
the left-hand side of the screen. If no destination has been specified using the GOTO key or
a route, no waypoints will be listed on the page.
(For more information on using routes, see page
56 in the Reference section.)

The GPS 12 MAP is a powerful navigation
system providing detailed mapping information
in a convenient, compact package. This
simulator tour is designed to show you the
basic features of your new GPS 12 MAP during
a simulated trip. The simulator tour assumes
that the receiver has been properly initialized as
outlined in the Getting Started section of this
manual, and that you have not changed any of
the factory default settings. If you have
changed any settings (position formats, units of
measure, etc.), the descriptions and pictures in
the tour may not match your configuration.
Once you’re familiar with the primary
functions of the GPS 12 MAP, you’ll be ready to
use your new receiver on a real trip to a
destination of your choice. The Reference
section of this manual may be consulted for any
additional questions you may have, or to learn
about the more advanced features of the GPS 12
MAP. For now, let’s get started on the Simulator
Tour!
If the GPS 12 MAP is currently off, we’ll need
to start by turning it on.
To turn the GPS 12 MAP on, press and
hold the red power key.
SIMULATOR TOUR
Selecting
Simulator Mode
The Welcome Page is displayed when the GPS 12
MAP is first turned on. After a brief self-test, it is replaced by a warning page.
To bypass the warning
page, press ENTER.
The Welcome Page will be displayed while
the unit conducts a self test. Once testing is
complete, the Welcome Page is replaced by a
warning page, then by the Satellite Status Page.
Since we’ll be using the simulator mode, we
don’t need to wait for the receiver to acquire
satellites.
WARNING: Keep in mind that the GPS 12
MAP does not track satellites in simulator mode
and should never be used for actual navigation.
The GPS 12 MAP cannot be turned on in
simulator mode. If you forget to change back to
normal operation before shutting the receiver
off, it will automatically return to normal mode
the next time you use the receiver.
The Satellite Status Page
appears next. For simulator mode operation,
there is no wait for the
unit to acquire satellites.
15
SIMULATOR TOUR
To select the simulator mode:
1. Press MENU to list the options for the Satellite
Status Page.
Selecting
Simulator Mode
2. Highlight ‘Start Simulator’ with the rocker keypad,
and press ENTER.
3. Press ENTER again to acknowledge the simulator
warning message.
Let’s look at the sequence of pages again.
The PAGE and QUIT keys are used to find your
way around on the GPS 12 MAP.
To cycle through the main pages:
1. Press PAGE to move through each of the main
pages in normal fashion.
2. Press QUIT to sequence through the main pages
in reverse order.
Select ‘Start Simulator’
from the Satellite Status
Page Options to enable
the built-in simulator.
The simulator imitates
satellite reception and
displays typical information on the Satellite Status Page. In this mode,
the unit is not actually
tracking satellites.
16
In normal mode operation, the GPS 12 MAP
would automatically sequence from Satellite
Status Page to Map Page once enough satellites
were received to determine your position. At
that point the receiver is ready to use for
navigation. Since we’re in simulator we won’t
see that automatic sequence of steps, but as you
cycle through the main pages, notice that the
simulator imitates satellite reception and shows
that information on the Satellite Status Page.
The Position Page will show the last known
position as a starting location. If you’ve already
initialized the receiver, as outlined in the
Getting Started section, the starting location
should be very close to your current position!
We’ll use this starting location from which to
begin our simulated trip. Let’s move on to the
Map Page to see where we are, create a destination and explore the navigation features of the
GPS 12 MAP.
To select the Map Page, press PAGE
repeatedly until it appears.
The GPS 12 MAP’s Map Page combines
digital charting with a number of user-selectable
features. Before we select our destination and
begin navigating toward it, let’s take a look at
some of those features.
Background Roads &
Railways
SIMULATOR TOUR
Using the
Map Page
Nearby Waypoints
Present Position
The map display shows
your present position using
a pointer icon in the center
of the screen. The Map
Page also shows any nearby lakes, rivers,
highways and towns. Use the zoom keys (IN
and OUT) to adjust the map to the desired
scale. The current scale is indicated in the
lower-left corner.
To change the map scale:
1. Press the IN zoom key to select a smaller scale
and display a smaller geographic area.
In the ‘TrackUp’ orientation, the map is automatically rotated to keep
your current direction of
travel at the top of the
display.
2. Press the OUT zoom key to select a larger scale
and display a larger geographic area.
The map can be oriented with the top of the
page always pointing north (‘North Up’),
oriented along your desired course (‘Course
Up’), or it can automatically rotate to keep your
current direction of travel at the top of the
screen (‘Track Up’).
Nearby waypoints are depicted on the map
with any one of over 50 different symbols, with
the waypoint name displayed directly above the
symbol. Let’s create a waypoint directly on the
map display to see how that process works,
then we’ll navigate to this new waypoint.
Use the IN/OUT zoom
keys to change the map
scale. The current scale
appears in the lower-left
corner of the map display.
17
SIMULATOR TOUR
Creating a
Waypoint
Select a five mile scale by pressing zoom
IN or OUT repeatedly.
Working from the Map Page is a simple
process that centers on the use of a reference
“arrow”. Controlled by the rocker keypad, the
reference arrow is an important tool allowing
you to pan to other areas on the map display,
create waypoints, view waypoint information
and create routes. To get a feel for using the
Map Page and the arrow, try the following
exercise:
1. Using the rocker keypad to move the arrow, try
following a highway (or other feature) near your
position. Simply press and hold one side of the
rocker keypad to move more quickly. Notice how
a data field appears above the map, showing the
bearing and distance from present position to the
cursor, along with the latitude/longitude of the
arrow’s position.
Use the rocker keypad to
pan to other areas on the
map display. When panning, an arrow appears
as a reference along with
a data field above the
map.
Place the panning arrow
over an on-screen item to
display a descriptive
name.
18
2. Using the rocker keypad, move the arrow in any
direction until you find a nearby city or town. Once
you find a nearby city or town, place the pointer on
it to highlight the location. Now, press ENTER to
create a waypoint at the arrow location and
display the New Map Waypoint Page.
3. If the name of the city or Waypoint Name Field
town is longer than six
characters, the GPS 12
MAP will abbreviate the
name when it creates the
waypoint. (If you select an
open location on the map,
where no city, town or
other feature is located, a
three-digit number is preassigned to the new
waypoint created at the
panning arrow location.
Waypoint Position Field
To change the name,
highlight the waypoint name field, press ENTER
and use the rocker keypad to enter a new name –
UP/DOWN to change the first character, RIGHT to
move to the next character, and repeat. Once the
new name is spelled out, press ENTER.)
4. A city symbol is assigned to the new waypoint, but
let’s use a special symbol to identify it. Highlight
the waypoint symbol field, using the rocker
keypad, and press ENTER. Use UP/DOWN on the
rocker keypad to select the ‘Information’ icon (‘?’)
and press ENTER.
5. To save the new waypoint, highlight ‘Done’ with
the rocker keypad and press ENTER.
SIMULATOR TOUR
Going to a
Waypoint
Now that we’ve created our new waypoint,
let’s see how the GPS 12 MAP is used to
navigate to it. The reference arrow can also be
used to GOTO any point on the map—even
without a waypoint already at that location—by
simply pressing GOTO. (We won’t try that
here. A waypoint named ‘MAP’ is automatically
created, so all the previous steps for creating
and naming a waypoint wouldn’t be needed.
You might want to experiment with this
procedure at the end of the Simulator Tour.) For
the Simulator Tour, we’ll stick with the
waypoint we just created.
To select the GOTO destination:
1. Press GOTO.
2. If the ‘All’ file tab is not selected, use the rocker
keypad to highlight this tab. (‘All’ will display a list
of all waypoints currently stored in memory.)
You can select a special
symbol to identify the
waypoint on the Map
Page.
3. Highlight the new waypoint you just created using
the rocker keypad, and press ENTER.
Notice that a course line appears on the map
display showing the way to our destination.
Imagine you’re about to depart. Maybe you’re
heading out from the marina or you’re about to
venture into the wilderness. What if you want
to return to your present position when you’re
done for the day? You have two options
available:
• You can mark your present position now
and save it as a waypoint, or
• You can use the TracBack feature at the
end of the day to retrace your steps –
following the same path you travelled,
but in reverse.
For now, we’ll mark our present position and
save it as a waypoint. (You might want to
experiment with the TracBack feature later. It’s
described on page 54.)
To select a GOTO destination, press GOTO
and highlight the desired
waypoint in the list. (You
may also need to select
the ‘All’ file tab to view
all waypoints.)
19
SIMULATOR TOUR
Marking
Present Position
To mark your present position:
1. Press and hold the ENTER/MARK key. The Mark
Waypoint Page will appear, with a default threedigit name for the new waypoint in the upper-left
portion of the page.
Let’s call our present position ‘HOME’. (If
you were at home when you initialized your
GPS 12 MAP, you might want to keep this
waypoint in memory for future use!)
To rename the waypoint and change its
symbol:
1. Use the keypad to highlight the name field, and
press ENTER.
2. Enter the new waypoint name (‘HOME’) using the
rocker keypad, and press ENTER. (Remember to
use UP/DOWN to change the character and
RIGHT to move to the next character field.)
To mark your present position and save it as a
waypoint, press and hold
ENTER. A three-digit
name is automatically
assigned to the waypoint.
3. Highlight the waypoint symbol field and press
ENTER.
4. Select the ‘Residence’ symbol, and press ENTER.
5. Move the cursor to the ‘DONE?’ prompt, and press
ENTER.
Now we have two waypoints in memory and
on the map: the city location we saved earlier
and ‘HOME’. It’s about time we get started, so
let’s plug a speed into the simulator to animate
the displays!
To enter a simulated speed and animate
the displays:
1. Press PAGE repeatedly until the Compass Page
appears.
From the Compass Page
you can increase/decrease the simulated
speed using the Up/Down
keys on the rocker pad.
20
2. Enter a simulated speed of ‘30’ (mph or knots)
using the rocker keypad. (Press UP on the rocker
keypad once to select ‘30’. The speed readout is
on the upper left corner of the Compass Page.)
3. Press PAGE (or QUIT) repeatedly to return to the
Map Page.
Notice the information on the map display is
slowly moving? That’s how it would look in
actual use as well. The background map
information and nearby waypoints will move
across the screen, while your current position
remains fixed in the center.
SIMULATOR TOUR
Compass
Page
The other primary navigation screens are the
Compass and Highway pages, with the Compass Page appearing first in the sequence of
main pages.
To view the Compass Page, press PAGE.
User-selectable data fields
The GPS 12 MAP’s
Compass Page provides
graphic steering guidance
to a destination waypoint.
The middle of the page
features a rotating
‘compass ring’ that shows
your course over ground
(track) while you’re moving,
and a bearing pointer that
indicates the direction of
the destination (bearing)
Bearing Pointer
relative to the course over
Compass Ring
ground. The compass ring
and pointer arrow work independently to
show—at a glance—the direction of your
movement and the direction to your destination. If the arrow points up, you are going
directly to the waypoint. If the arrow points any
direction other than up, turn toward the arrow
until it points up—then continue in that
direction. The distance to the next waypoint,
time to the next waypoint and current speed
are displayed to the right of the graphic
compass display. To see how all this works on
our simulated trip, let’s head off course and
watch the displays change.
To move off course / on course in simulator
mode, use the LEFT/RIGHT keys on the rocker
keypad.
The background map
moves while keeping
your current position at
the center of the map
display.
The Compass Page will
also guide you to your
destination. The rotating
’compass ring’ shows the
direction of travel (track)
and the bearing pointer
indicates the direction to
your destination.
21
SIMULATOR TOUR
Highway
Page
Use the LEFT/RIGHT
keys on the rocker keypad to move off course.
To return to your course,
steer toward the highway centerline.
When you reach your
destination, the highway
will end at the waypoint
marker. Also note the
‘distance to next’
waypoint readout. If you
pass the waypoint the
pointer will point down.
22
To view the Highway Page, press PAGE.
The Highway Page provides a graphic
highway display that shows your movement
relative to the desired course. The line down the
middle of the highway represents your desired
course. As you navigate toward your destination, the highway will actually move, indicating
the direction you’re off course. To stay on
course, simply steer toward the center of the
highway. As you approach the waypoint, the
highway will end at the final destination. When
the waypoint marker is at the bottom center of
the highway display, you’ve arrived at your
destination. A track compass also shows your
current track directly above the highway
display, making it easy to see at a glance which
way you’re headed.
The pointer arrow at the top of the page
indicates the direction to the destination
waypoint (bearing) relative to the direction you
are moving (track). If the pointer points straight
ahead, you’re heading directly to the waypoint.
If not, turn in the direction of the pointer and
the pointer will swing around, pointing straight
ahead as you begin moving toward the destination waypoint. Try moving on course/ off course
again using the rocker keypad and watch as the
highway display and bearing pointer change.
That’s it! You’ve covered the basics and
you’re ready to venture off on your own.
Operating the GPS 12 MAP is just as simple as
you’ve seen here in the Simulator Tour, but in
real applications you won’t need to change
speed and track with the rocker keypad. That’s
all done automatically utilizing information
from the GPS satellites as you move about.
Before ending the tour, try a few experiments
of your own, such as going back to the ‘HOME’
waypoint, retracing your steps utilizing the
TracBack feature, or creating a few more
waypoints. Use the Reference section of this
manual for more ideas.
To end the Simulator Tour, turn the GPS
12 MAP off, press and hold the red
power key.
The GPS 12 MAP’s Satellite Status Page
provides a visual reference of various receiver
functions, including current satellite coverage,
receiver operating mode, battery level and
position accuracy. As the receiver locks onto
satellites, a signal strength bar will appear for
each satellite in view, with the appropriate
satellite number (01-32) underneath each bar.
The progress of satellite acquisition is shown in
three stages:
• No signal strength bars— the receiver is
looking for the satellites indicated.
• Hollow signal strength bars— the
receiver has found the satellite(s) and is
collecting data.
• Solid signal strength bars— the receiver
has collected the necessary data and the
satellite(s) is ready for use.
Each satellite has a 30-second data transmission that must be collected (hollow bar status)
before that satellite may be used for navigation
(solid bar status). Once a fix has been calculated, the GPS 12 MAP will then update your
position, track, and speed by selecting and
using the best satellites in view. You can also
access the GPS 12 MAP’s backlight and contrast
feature from this or any main page.
To adjust the screen contrast and/or
backlighting:
REFERENCE
Satellite Status
Page
The Satellite status Page
shows where the satellites
are and how strong the
signal is from each one.
A solid signal bar means
the satellite is ready to use.
1. Press LEFT or RIGHT on the rocker keypad to
adjust the level of contrast, and press ENTER to
save the new contrast setting.
2. Press UP or DOWN on the rocker keypad to
adjust the level of backlighting, and press ENTER
to save the new backlight setting.
Sky View and Signal Strength Bars
The sky view and signal strength bars give
you an indication of what satellites are visible to
the receiver, whether or not they are being used
to calculate a position fix, and the signal quality.
The satellite sky view shows a bird’s-eye view of
the position of each available satellite relative to
the unit’s last known position. The outer circle
represents the horizon (north up); the inner
circle 45º above the horizon; and the center
point directly overhead.
Use the LEFT/RIGHT
keys on the rocker keypad
to adjust the screen contrast and the UP/DOWN
keys to adjust the backlighting. Press ENTER to
save the settings.
23
REFERENCE
Satellite Status
Page
‘2D Navigation’ means
the unit has determined
a horizontal position
(latitude/longitude), but
is unable to determine
altitude.
‘3D Navigation’ means the
unit has determined a
horizontal and vertical position (latitude, longitude,
and altitude.) The unit is
ready for navigation.
24
You can use the sky view to help determine if
any satellites are being blocked, and whether
you have a current position fix (indicated by a
‘2D Navigation’ or ‘3D Navigation’ in the status
field). You can also set the sky view to a ‘Track
Up’ configuration, causing the top of the sky
view to align along your current track heading.
When the receiver is looking for a particular
satellite, the corresponding signal strength bar
will be blank and the sky view indicator will
not be highlighted. Once the receiver has found
the satellite, a hollow signal strength bar will
appear, indicating that the satellite has been
found and the receiver is collecting data from it.
The satellite number in the sky view will appear
highlighted. As soon as the GPS 12 MAP has
collected the necessary data to calculate a fix,
the status field will indicate a 2D or 3D status.
(For ‘2D’, you may need to enter your altitude.
See page 27.)
Receiver Status
Receiver status is indicated at the top of the
page. The status will be shown as one of the
following conditions:
Searching— the GPS 12 MAP is looking for
any available satellites in view.
AutoLocate— the GPS 12 MAP is initializing
and collecting new almanac data. This
process can take up to 5 minutes, depending
on the satellites currently in view.
Acquiring— the receiver is collecting data
from available satellites, but has not collected
enough data to calculate a position fix.
2D Navigation— at least three satellites with
good geometry have been locked onto and a
2-dimensional position fix (latitude and
longitude) is being calculated. ‘2D Diff’ will
appear when you are receiving DGPS
corrections in 2D mode.
3D Navigation— at least four satellites with
good geometry have been locked onto, and your
position is now being calculated in latitude,
longitude and altitude. ‘3D Diff’ will appear when
you are receiving DGPS corrections in 3D mode.
Poor GPS Coverage— the receiver isn’t
tracking enough satellites for a 2D or 3D fix
due to bad satellite geometry.
Not Usable— the receiver is unusable,
possibly due to incorrect initialization or
abnormal satellite conditions. Turn the unit
off and back on to reset, and reinitialize the
receiver if necessary.
REFERENCE
Satellite Status
Page
Simulating Nav— the receiver is in simulator mode.
‘Need to Select Initialization’ Prompt
If no satellites are received for several
minutes (or an insufficient number of satellites
are received to determine a position fix) a
message will appear, prompting you to initialize
the receiver (see page 3). This allows you to
specify a starting location from which to search
for satellites, or to enable the AutoLocate
feature, and is useful if you have traveled over
500 miles with the receiver off. (This message
will automatically appear when you first use
your GPS 12 MAP. The prompt may also appear
during normal use if the antenna is shaded or
the unit is used indoors.)
‘Poor GPS Coverage’
means the receiver isn’t
tracking enough satellites
to establish a position.
Check for obstructions,
trees, buildings, etc.
Battery Level Indicator
The Satellite Status Page also features a
battery level indicator, located to the left of the
sky view, which displays the strength of the
unit’s batteries. The battery indicator will not
appear if the receiver is operating on external
power.
NOTE: The battery level indicator is calibrated
for alkaline batteries. NiCad and lithium batteries
will display the battery level differently due to
voltage differences. To display battery level
accurately select the appropriate type, as described
on page 73. The GPS 12 MAP features an internal
10-year lithium battery that will maintain the unit’s
memory when the receiver is not running off
batteries or external power.
This message appears if a
position cannot be determined after several minutes. After acknowledging
the message, select ‘Use
Map’ or ‘AutoLocate’
from the options list.
25
REFERENCE
Satellite Status
Page
The Satellite Status Page
Options allow you to enable the built-in simulator,
or initialize the receiver.
EPE and DOP
The Satellite Status Page also indicates the
accuracy of the position fix, using Estimated
Position Error (EPE) and Dilution of Precision
(DOP) figures. DOP measures satellite geometry
quality (i.e., number of satellites received and
where they are relative to each other) on a scale
from one to ten. The lowest numbers are the
best accuracy and the highest numbers are the
worst. EPE uses DOP and other factors to
calculate a horizontal position error, in feet or
meters.
Satellite Status Page Options
Many features of the GPS 12 MAP are menu
driven. Each of the main pages has an options
menu, allowing you to custom tailor the

Position Page
The second page in the GPS 12 MAP’s main
page sequence is the Position Page. This page
shows you where you are, what direction you’re
heading, and how fast you’re going, and it’s
most useful when you are traveling without an
active destination waypoint. The graphic
heading display at the top of the page indicates
the direction you’re heading, or track, only
while you’re moving.
Directly below this display are the speed,
average speed, trip timer, trip odometer and
sunrise/sunset fields (default). The sunrise/
sunset times indicated are for your present
position. These times, and the current time
display at the bottom of the page, can be
displayed in local or UTC (universal) time. The
lower part of the page shows your current
latitude and longitude in degrees and minutes
(default). The GPS 12 MAP uses this basic
information to mark exact positions as
waypoints, which help guide you from one
place to another. Average speed, sunrise and
sunset times (at your present position) also
appear on the Position Page (as default selections). Units of measure and the position
readout are selectable from the Main Menu, as
outlined on page 74. ‘Trip Computer’ functions—such as average speed, max speed, trip
odometer and trip timer—can each be reset
from the Main Menu, as described on page 70.
Many features of the GPS 12 MAP are menu

reduces the effects of selective availability on
position error and results in a more accurate
position reading.
To average position samples and save the
result as a waypoint:
1. Highlight ‘Average Position’ and press ENTER.
The Average Position Page will appear. Observe
the ‘Estimated Accuracy’ and ‘Measurement

The GPS 12 MAP features a powerful real-time
moving map that can do much more than just
plot your course and route. The Map Page also
displays background detail, including geographic
names, lakes, rivers, coastlines and highways.
You can load maps with detailed information
for specific geographical areas. (See MapSource
Info on page 36) An on-screen cursor lets you
pan ahead to nearby waypoints, determine the
distance and bearing to any map position, mark
new waypoints while you navigate or retrieve
exit information. The GPS 12 MAP also features
dedicated zoom keys for instant zooming (see
page 2). The map portion of the page displays
your present position as a pointer icon, with
your track and/or route displayed as small points
on the screen (an electronic bread crumb trail, if
you will). Nearby waypoints are represented with
names and symbols. You may select which
features are shown via the Map Page Options (see
pg. 35).
The data window above the map displays the
time and distance to next waypoint, plus your
current speed (all defaults). A bearing pointer
lets you know if you’re heading toward your
destination. (If the pointer points straight
ahead, you’re heading directly to it.) Each data
field may be configured to display any one of
twenty-four data options.
Zooming and Panning
There are three main functions you can
perform from the Map Page: zooming, panning,
and pointing. The map has 24 map scales (from
120 feet to 500 miles, or 30 meters to 800 km)
which are selected by pressing the IN and OUT
zoom keys. The current map scale is indicated
in the bottom left corner of the map display.

2. Press zoom OUT to see a larger area with less
detail.
Another function on the Map Page is the pan
function, which allows you to move the map
with the keypad in order to view areas beyond
the current map.
To activate the pan function:
1. Use the rocker keypad to move the map in any
direction, including diagonally.
As you begin to pan on the map, an arrow
appears. This arrow will serve as a target marker
for the map. When the arrow is placed on an
object, the name of that object will be highlighted. (If the name wasn’t originally displayed
it will appear when the arrow is placed on the
object.) This feature applies to waypoints,
roads, lakes, rivers—pretty much everything
displayed except route lines and track log data.
When a waypoint name is highlighted, you
can review information about the waypoint, list
waypoint options, or execute a GOTO right
from the Map Page.

navigation is not possible due to obstructions or
terrain.
The middle of the page features a rotating
‘compass ring’ that shows your course over
ground (track) while you’re moving. (Your
present course over ground is indicated at the
top of the compass ring.) A bearing pointer, in
the middle of the compass ring, indicates the
direction of the destination (bearing) relative to
the course over ground. The compass ring and
pointer arrow work independently to show—at
a glance—the direction of your movement and
the direction to your destination. For instance,
if the arrow points up, you are going directly to
the waypoint. If the arrow points any direction
other than up, turn toward the arrow until it
points up—then continue in that direction.
At the top of the page are four user-selectable

The GPS 12 MAP’s Highway Page also
provides graphic steering guidance to your
destination, by using a graphic highway display.
At the top of the page are four user-selectable
data fields that display current speed, distance
and time to next waypoint, and a bearing
pointer (defaults). The bearing pointer always
points to the destination waypoint (or the next
waypoint when using a route) relative to the
direction you are moving (track). If the bearing
pointer points straight ahead, you are heading
directly to your destination. If the bearing
pointer points any direction other than up, turn
toward the arrow until it points up—then
continue in that direction. Each data field may
be configured to display any one of twentythree data options.
The graphic heading compass beneath the
data fields indicates the direction you are
moving (track). Directly below the heading
compass, the highway display provides visual
guidance to the destination waypoint and keeps
you on your intended course line. Your course
is represented by the center line down the
middle of the graphic highway. As you head
toward your destination, the highway perspective will move to indicate your progress to the
waypoint and which direction you should steer
to stay on course. When you are navigating a
route, the highway display will show each route
waypoint in sequence, with the route course
indicated by a black highway. Nearby waypoints
not in the route will also be displayed. You can

The GPS 12 MAP stores up to 500 waypoints,
with a selectable symbol and comment available
for each waypoint. Waypoints can be created
using five methods:
Mark Present Position— your present
position can be captured and saved as a
waypoint using the ENTER/MARK key.
On Map— a new waypoint position can be
created directly on the map display using the
panning arrow.
Text Entry— waypoints can be created by
entering position coordinates manually (from
a chart, etc.) or by referencing bearing and
distance from a previously stored waypoint
(or present position).
Average Position— position samples can be
averaged over time and the result saved as a
waypoint. Averaging reduces the effects of
selective availability and improves the
accuracy of the position reading. (See page
29 for more info.)
Nearest Locations— nearest cities or
highway exits can be saved as waypoints
from the nearest locations pages. (See page
49 for more info.)
Marking Present Position
The GPS 12 MAP’s mark feature lets you
quickly capture your present position in order
to create a new waypoint. You must be locked
onto satellites, with a valid position fix, to mark
your present position.
To mark your present position:

The GPS 12 MAP can navigate to a destination using any of four different methods:
GOTO— lets you select a waypoint as your
destination and quickly plot a direct course
from present position to that waypoint.
MOB (man overboard)— captures your
present position, saves it as a waypoint and
sets a course back to the position for quick
response in an emergency.
TracBack— allows you to retrace your path
using the track log automatically stored in
the receiver’s memory. This eliminates the
need to store waypoints along the way. (See
page 54 for more information about
TracBack.)
Routes— allows you to manually create a
sequence of intermediate waypoints which
lead you to your final destination. The GPS
12 MAP will store up to 20 reversible routes,
with up to 30 waypoints in each route.
GOTO Navigation
The easiest way to select your destination is
by using the GOTO key. The GOTO key can be
used by itself, after highlighting a waypoint
name on a list, or after designating a position
on the map display.
To GOTO a waypoint:
1. Press GOTO. The GOTO Page shows a series of
file tabs for ‘Recent’ waypoints, ‘All’ waypoints,
‘Nearest’ waypoints or ‘Spell n Find’.

REFERENCE
TracBack
Clear any old data from
the active log before you
depart. This defines the
starting point for a
TracBack Route.
The TracBack navigation feature allows you
to retrace your path using the track log automatically stored in the receiver’s memory. This
eliminates the need to manually store waypoints
along the way. A track log is an electronic
breadcrumb trail, showing the path you have
travelled. Your GPS 12 MAP can be set to
automatically record track log points any time
the receiver is on and locked onto satellites (see
page 70).
TracBack routes are created by reducing your
track log into a route of up to 30 waypoints and
activating the new route in reverse order along
those waypoints. Once activated, a TracBack
route will lead you back to the oldest track log
point stored in memory, so it’s a good idea to
clear the active track log at the beginning of
your current trip (e.g., at the dock or trailhead),
before you get started.
To clear the active track log and define a
starting point for a TracBack:
1. Press MENU twice to display the Main Menu.
2. Highlight ‘Track Logs’ and press ENTER.
3. With the ‘Active Log’ highlighted press MENU to
display the options list.
4. Highlight ‘Clear Active Log’ and press ENTER.
5. Press ENTER to delete the track log data. (Or
press QUIT to cancel.)
To create and activate a TracBack route:
1. Enable track log recording and leave the GPS 12
MAP on to automatically record track log positions
while under way. Refer to page 70 for more
information on track log settings.
2. Press MENU twice to display the Main Menu.
A TracBack route can
also be created from the
GOTO Options by
pressing GOTO, followed by MENU and
selecting ‘TracBack’.
54
3. Highlight ‘Track Logs’ and press ENTER.
4. Highlight the desired track log (‘Active Log’ or ‘Saved
Logs’) and press MENU to display the options list.
5. Highlight ‘TracBack’ and press ENTER to create/
activate the TracBack route. (A message box will
appear while the GPS 12 MAP analyzes the data
and creates the route.)
Once a TracBack has been activated, the GPS
12 MAP will take the track log currently stored
in memory and divide it into route segments,
called ‘legs’. Up to 30 track log waypoints
(labeled ‘T###’, e.g. ‘T001’) will be created to
mark the most significant features of the track
log in order to duplicate your path as closely as
possible. To gain the most benefit from the
TracBack feature, keep the following tips in
mind:
• Always clear the track log at the point
you want to return to (boat ramp, dock,
trailhead, etc.)
• The ‘Record Mode’ on the Track Logs
Page must be set to ‘Wrap’ or ‘Fill’.
• There must be at least two track log
points stored in memory to create a
TracBack route.
• If there is not enough available memory
to add more waypoints and create a
TracBack route, you will be alerted with
a ‘waypoint memory full’ message. The
receiver will use the available waypoints
to create a route with an emphasis on the
track log data closest to the destination.
Also, existing TracBack waypoints (‘T###’)
that are not contained in routes will be
erased to free more memory. The GPS 12
MAP will create new waypoints using the
first available three-digit number.
• If the Track Logs Page ‘Interval’ field is
set to ‘Time’, the route may not follow
your exact path. (Keep the ‘Interval’ field
set to ‘Resolution’ for best results.)
• If the receiver is turned off or satellite
coverage is lost during your trip,
TracBack will draw a straight line
between any point where coverage was
lost and where it resumed.
• If there are frequent changes in direction
and distance in your track log, 30
waypoints may not accurately depict your
exact path. The receiver will then assign
the 30 waypoints to the most significant
points of your track log, and simplify
segments with fewer changes in direction.
REFERENCE
TracBack Tips
A TracBack route contains a series of
waypoints labeled ‘T###’
that approximate your
previous route of travel.
‘Wrap’ will overwrite the
old track log data in
memory, once all
memory has been used.
‘Fill’ will record data until memory is full, then
stop.
