The GARMIN GPSMAP is a powerful electronic charting/navigating system
that provides detailed chart coverage and convenient control of many
advanced features right from the graphic charting page. This tour is designed
to take you through the basic pages and functions of the GPSMAP system.
Once you’re familiar with the main pages and functions of the unit, refer to the
reference section for instructions on performing specific tasks and functions.
GPSMAP TOUR
Power On
Before beginning the GPSMAP tour, make sure the main unit and antenna
have been properly installed (see Appendices A & B). Note that our tour will
use the GPSMAP’s built-in worldwide database and the simulator mode, so you
won’t have to install a chart cartridge or acquire satellites for this exercise. The
tour assumes you have not changed any of the default settings for the unit. If
you have changed any settings (position formats, units of measure, etc.), the
descriptions and pictures in the tour may not match your configuration.
Powering Up and Starting the GPSMAP Tour
The GPSMAP’s power and screen backlighting are controlled by the J
key at the bottom left of the unit. To turn the GPSMAP on:
1. Press and hold the right side of the J key until the power tone sounds.
2. Once the welcome page appears, press the C key to acknowledge the
mariner’s warning notice and begin operation.
To adjust the screen backlighting level:
The GPSMAP system is designed as an aid to
navigation, and is not intended to replace the
use of government-approved charts and traditional navigation practices. Make sure you
read and understand the mariner’s acknowledgement before using the unit.

Menu
The GPSMAP system is built around a powerful graphical Map Page. The
Map Page combines digital electronic charting with a complete display of
important navigational data and easy access to advanced features. After
completing the tour, you’ll be able to perform most navigation, waypoint and
route functions directly from the Map Page. Before we start creating waypoints
and routes, let’s take a brief look at its various features and displays.
The Data Window (at the right side of the
screen) and the Softkey Menu Display (at the
bottom of the screen) may be turned off for a
full page display of cartography:
• To turn the Data Window off, press B.
• To turn the Softkey Menu off, press G.
The Map Page can be broken down into three main sections: map display,
data window and softkey menu.
The map display shows your boat as a wedge icon on an electronically
generated chart, complete with geographic names, markers, buoys and depth
contours. It also displays your track, routes and nearby waypoints. An
on-screen target cursor lets you pan to other map areas, determine the range
and bearing to a position and perform various route and waypoint functions.
The data window provides a digital display of navigation data, in relation
to your present position, the target cursor position or a particular waypoint.

The destination field, located at the top of the data window, shows your
bearing (BRG) and distance (DIS) to a destination waypoint or to the cursor. It
also displays your crosstrack error (XTK) and turn (TRN) heading to an active
destination. The XTK value is the distance you are off a desired course (left or
right), while TRN represents the direction (left or right) in degrees between
your course over ground (COG) and the bearing to your destination.

GPSMAP TOUR
Using the Target Cursor
Using the Map Page is a simple process that centers around the use of the
cursor. Controlled by the arrow keypad, the cursor is an important tool that
can be used as a distance and bearing marker, to create new waypoints and
routes, and to review position data of on-screen waypoints, buoys and
markers. Try moving the cursor using the following exercise:
1. Use the L key to set the map scale to 64 n.m.
2. Your boat should be in the center of the map display, near Andros Island and
Nassau (the position you entered earlier).
3. Press the bottom arrow of the K keypad to move the cursor down to the first
lat/lon grid South of your boat’s position.
As you move the cursor, the distance and
bearing from your present position to the
cursor will be displayed in the destination
field (at the top right of the screen).
The cursor’s position coordinates will be displayed in the position field (below the speed
and course field).
While in cursor mode, the boat icon will
continue to move, and may go off screen to
accommodate the scrolling cursor.
6
4. Using the K keypad to move the target crosshair in each direction, try following the outline of the lat/lon grid closest to your boat. Notice how the
destination field of the data window displays the distance and bearing from
your position to the target cursor, with the cursor’s coordinate position
indicated in the position field.
5. Press the A key to eliminate the cursor and re-center your position on the
map display.
As you become more familiar with using the cursor, you’ll see that the map
display actively scrolls forward with your panning, letting you explore areas
around the world (even outside of your current G-chartTM coverage) and create
waypoints and routes. Wherever you move the cursor, you’ll always be one
A keystroke away from returning to your present position.

To continue the tour, let’s mark our simulated present position for reference:
1. Press the F key to capture your present position as a waypoint.
GPSMAP TOUR
Marking a Position
The Mark GPS Position window will appear, with a default three-digit
waypoint name and symbol. By pressing the C key, you can confirm the
waypoint with the default name and symbol, but let’s change the name and
symbol to something a little more meaningful:
1. Use the K keypad to move the field highlight to the ‘Wpt’ field and press C.
2. Enter the name ‘DAY1’ with the K keypad, pressing C after each character.
3. After you’ve entered the last letter, press the OK softkey to confirm the name.
4. The field highlight will move to the waypoint symbol field. Press C to begin
selection of a new waypoint symbol.
5. Use the K keypad to highlight the fish symbol (on the second line of the
window) and press the C key.
6. The field highlight will move to the comment field, where you may enter a 20character comment (the default comment is the date and time of creation).
7. Press C to begin entry of a comment.
8. Use the K keypad to enter ‘TOUR’ in the comment field, pressing the C key
after each character.
The GPSMAP system stores over 1900
alphanumeric waypoints, with selectable
graphic icons and a user-defined comment
field. If you mark a navaid position that
appears on a G-chart electronic cartridge,
the default comment will automatically select
the navaid text associated with the marker.
9. Press the OK softkey to accept your comment.
10. Use the K keypad to highlight the OK field.
11. Press the C key to save your new waypoint.

GPSMAP TOUR
Creating a Route
Now that you’ve marked a waypoint for your starting position, let’s make a
route to navigate using the ROUTES softkey. (For the purposes of this tour,
make sure that the current map scale is still at 64 n.m.)
1. Press the ROUTES softkey to begin creating a route.
2. Use the K keypad to highlight the Route 1 field and press C.
I
Whenever the cursor comes in close proximity
to an on-screen waypoint or navaid, it will
‘snap’ to and highlight its on-screen icon.
Once an on-screen marker has been highlighted, destination and position information
will be displayed in the data window.
This feature makes it easy to review waypoint
positions right from the map display.
The GPSMAP system can store 20 reversible routes of up to 50 waypoints each.
Routes 1-19 are used as storage routes, with Route 0 always serving as the active
route. Although you may create a route in the Route 0 position, be aware that it will
automatically become the active route upon completion. If you want to save a route
created in the Route 0 position, be sure to copy it to another storage route, as it will
be overwritten by the next route activation (see Section 8 for more details on routes).
As the GPSMAP returns to the Map Page, you’ll notice several changes. The
map display will now show the cursor as an arrow at your present position,
with the prompt field indicating instructions for adding waypoints to your
route. To select the DAY1 waypoint as your first route waypoint:
1. Press the C key to add the waypoint to the route.
Now add the next waypoint to the route:
1. Use the K keypad to move the arrow cursor as close as possible to the
following coordinates: N 24º 27.371’, W 077º 42.407’.
2. Press C to save the waypoint position.

Now add the final waypoint to the route:
1. Use the K keypad to move the arrow cursor as close as possible to the
following coordinates: N24º21.777’, W077º51.424.
GPSMAP TOUR
Modifying a Route Graphically
Activating a Route
2. Press the C key to save the waypoint position.
3. Press C to confirm the default waypoint name, symbol and comment.
We now have a three waypoint route from our present position to
waypoint 002. To activate the route and begin navigation:
1. Press the EXIT softkey to quit the route creation mode.
2. Press the ACTIVTE softkey.
The GPSMAP will return to the Map Page, with your active route (Route 0)
shown on the map display and the ‘active to’ waypoint (001) displayed in the
destination field. The speed and course field tells us we’re getting nowhere
fast, so let’s go to the Highway Page and enter a speed for our simulated trip:
1. Press the I key to display the Highway Page.
The Highway Page provides you with a large, digital display of navigation
data and graphic steering guidance to an active destination via a three-dimensional perspective of your course. As you head toward your destination, the
middle of the screen provides visual guidance on a moving “graphic” highway.
Your present position is at the bottom 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 steer toward the center
of the highway.

Navigating a Route
The active destination waypoint is displayed at the top of the screen, with
the ETE (estimated time enroute) and ETA (estimated time of arrival) based on
your present speed and course at the bottom.
The distance and bearing to the first route waypoint, along with your current speed and course over ground (SOG and COG), are indicated along the
right-hand side of the screen. The SOG and COG fields can be changed to
display velocity made good (VMG) and turn (TRN). To toggle the speed and
course displays, press the B key.
Now enter a speed of 60 knots for our simulated trip:
1. Press the SOG/COG softkey to display the Simulator SOG/COG window.
2. Press the C key to begin data entry.
3. Use the K keypad to enter a speed of 60 knots, pressing the C key after
each character entry.
4. Once you’ve entered your speed, press the EXIT softkey.
The Simulator SOG/COG window lets you
specify the speed and course for the simulator
mode. By leaving the COG field value at
the default setting, the GPSMAP system will
automatically set a course directly to your
destination.

Active Route Page
1. Press the I key.
The Active Route Page shows each waypoint of the active route in sequence,
along with the desired track, distance and ETE or ETA to each waypoint from
your present position. As you navigate a route, the waypoint list will automatically update to list the next ‘active to’ waypoint first, followed by the remaining route waypoints in sequence. From the Active Route Page, you can:
1. Scroll through the entire list of route waypoints using the K key.
2. Review a highlighted waypoint by pressing the C key.
3. Change the ETE field to display ETA by pressing the B key.
Let’s go back to the Map Page to look at our progress:
1. Press the E key.
As you travel along your route, your boat will move across the map display,
leaving a track plot of your course. You may have some difficulty differentiating track plots and route legs at the 64 n.m. scale, so try zooming down past
the built-in database with L to get a good view of the track plot.

The GPSMAP 215/225 Satellite Status Page provides a visual reference of
various receiver functions, including current satellite coverage, receiver
operating mode and present position or DGPS status. The status information
will give you an idea of what the receiver is doing at any given moment.
The sky view and signal strength bars give you an indication of what
satellites are visible to the receiver and whether or not they are being tracked.
The signal strength is shown on a bar graph for each satellite, with the satellite
number below. When a satellite is visible but not being tracked, the strength
bar will remain blank and the sky view indicator will remain highlighted.
The sky view shows a bird’s eye view of the position of each satellite relative
to the receiver’s last known position. The outer circle represents the horizon
(North up); the inner circle 45º above the horizon; and the center point a
position directly overhead. Use the sky view to determine if there are
obstructions shading your reception of GPS signals.
In this example, satellites 5, 21, 23, 25 and 29 are
currently being tracked, with the corresponding
signal strength bars indicating the relative strength
of the signals. Satellites 3, 9, 15, 30 and 31 (shown
with numbers highlighted) are visible, but are not
currently being tracked. Satellite 8 is being received
(as indicated by a hollow bar), but the data is not
yet available for use in determining your position.
NOTE: For first time operation, GPSMAP 215 and
225 units may require 5 minutes to collect initial
satellite almanac data and establish a present
position. You may speed up the initial acquisition
process by entering an initial position (see page 16).

The Satellite Status Page also shows receiver status and the current horizontal accuracy at the top left of the screen. The operating mode field will indicate
whether the receiver is acquiring satellites, or is in simulator, 2-D, 2-D
differential, 3-D or 3-D differential mode; with the current dilution of
precision (DOP) and estimated position error (EPE) displayed below.
DOP is a measurement of satellite geometry quality, measured on a scale of
one to ten (lower numbers being the best, higher numbers the poorest). The
EPE uses the DOP and other factors such as signal quality to calculate a
horizontal position error in feet or meters.
At the top right of the screen, your present position and the current date and
time are displayed in the position window. The position shown will be the
receiver’s last calculated position. If you have moved more than 300 miles from
your last position, you may want to enter a more accurate position to speed up
satellite acquisition (or select AutoLocate™ mode, as described on page 48).
You may enter your own position coordinates—by data entry or graphically—
whenever the GPSMAP is acquiring satellites or is in simulator mode.
Whenever your GPSMAP is operating with
a DGPS beacon receiver, the position window
will be replaced by a beacon receiver status
window. This window will display the beacon
receiver status, the signal-to-noise ratio (SNR),
and the distance from your beacon receiver to
the DGPS transmitter.( If available)
GPSMAP 215/225 units purchased without the
internal beacon receiver can be upgraded to
DGPS accuracies using the GARMIN GBR 21
or GBR 23 beacon receiver.

The GPSMAP Map Page provides a comprehensive display of electronic
cartography, plotting and navigational data. It is the primary page used for
navigating with the GPSMAP system. The Map Page can be broken down
into three main sections: map display, data window and softkey menu.
The map display shows your boat on an electronically generated chart,
complete with geographic names, navaids, depth contours and a host of other
chart features. It also plots your track and displays any routes and waypoints
you create. An on-screen cursor lets you pan and scroll to other map areas,
determine the distance and bearing to a position, and perform various route
and waypoint functions. The GPSMAP system has a built-in worldwide
database to 64 n.m. (see Appendix F for built-in coverage map), with more
detailed coverage available through the use of G-chartTM data cartridges (see
Section 10 for installing and using G-chartTM cartridges).
Your boat’s position is represented by a wedge
icon, with your track plot shown as a dotted
line (GPSMAP215) or a solid yellow line
(GPSMAP225).
To select what chart features are displayed
on a particular chart scale, refer to the Map
Configuration section on pages 23-24.

The map display uses the cursor keypad and a set of hard keys to control
most map display functions. The L, A, C and E keys, combined
with the K keypad lets you select zoom ranges, move the cursor and display
chart outlines. Two basic map operating modes determine what cartography is
shown on the map display: boat mode and cursor mode. Boat mode pans the
cartography to keep the present position marker within the display area, while
cursor mode pans the cartography to keep the cursor within the display area.
The GPSMAP system will always power up in the boat mode, with your
vessel centered on the map display. In boat navigation mode:
• Your movement is shown by the map scrolling past the centered boat.
• Whenever sufficient map coverage is not available to keep the boat centered,
the boat icon will move toward the edge of the display.
• If the boat icon attempts to go off the display, the zoom level may need to be
adjusted to keep cartography on screen.
Boat Mode
Whenever the K keypad is pressed, the GPSMAP will enter cursor mode.
In cursor mode:
• The cursor can be moved over the map display using the K keypad.
• Whenever the cursor reaches the edge of the display, the map will scroll
forward under the cursor. Keep in mind that the boat icon will move with the
map scrolling, and may go off the display screen (you may not be able to see
your present position).
• When the cursor is stationary, a fixed coordinate position will appear in the
position field. Note that the distance and bearing, displayed in the destination
field, will change as your boat’s position changes.

As you move the cursor, the distance and bearing from your present
position to the cursor, will be displayed in the data window, with the cursor’s
position coordinates shown in the position field. Keep in mind that when the
cursor is stationary, the distance and bearing from your present position will
change as your boat moves.
The cursor may also be used to ‘snap’ to on-screen waypoints and navaids,
allowing you to review the selected position directly from the map display
To select an on-screen waypoint or navaid with the cursor:
Snapping to an on-screen waypoint
1. Use the K keypad to move the cursor to the desired waypoint or navaid.

scale displayed at the bottom of the data window.
To select a map scale:
1. Press the arrow icon on the right or left side of the L key to zoom in or out.
The GPSMAP will display cartography as long as there is chart information
available for the range you’ve selected. Zooming operation will conform to the
following default settings:
• When the selected zoom range is covered by either the internal database or a
G-chartTM data cartridge, cartography will be displayed.
• When the selected zoom range is covered by both the internal database and
a G-chartTM cartridge, cartography will be displayed using the data with the
best resolution.
Overzoom Mode
• When the selected zoom range exceeds the resolution of the chart in use by
up to two settings, OVERZOOM cartography will be displayed. The display
will not show any filled landmass areas, and an ‘Ovr Zm’ warning will appear
in the scale field and the lat/lon grid will be turned on regardless of the map
configuration setting. Although OVERZOOM cartography provides some level of
map detail, additional caution should be used while navigating.
• When the selected zoom range exceeds the resolution of the chart in use by
more than two settings, a ‘No Map’ warning will appear and all cartography will
be replaced by a TRACK PLOT display. The lat/lon grid will be displayed regardless of the map configuration setting. Additional caution should be used while

The second section of the Map Page is the data window, located at the right
side of the screen display. The data window provides a digital display of
navigation data in relation to your present position, the cursor position or a
particular waypoint.
The top area of the data window includes the destination fields, which
display the bearing and distance to the destination waypoint indicated, with
crosstrack error (XTK) and turn value (TRN) shown at the bottom. If there is
not an active destination waypoint, ‘Not Active’ will be indicated above the
destination fields. The XTK value is the distance you are off a desired course,
while TRN represents the direction in degrees between your course over
ground (COG) and the bearing to your destination. Whenever the cursor is in
use, the destination field will display the distance and bearing from your
present position to the cursor.
The speed and course fields, located below the destination fields, display
your present speed and course over ground (SOG and COG). Directly below
these fields are the arrival and status fields. The arrival fields display your
velocity made good (VMG) and estimated time enroute (ETE). VMG is the
speed you are closing in on a destination along the desired track, with the ETE
representing the total time left to your destination based on your current
VMG. Whenever the cursor is in use, the arrival fields will be replaced by a
position field, which displays the coordinates of the cursor.
The status field, located directly below the arrival field, indicates the
operating mode and map scale currently in use. When the cursor is used to
‘snap’ to an on-screen waypoint or navaid, the arrival and status fields will be
replaced with a waypoint review field, showing the name, position, icon and
comment for the selected on-screen position.

Map Calibrations
WARNING!
The map calibration function is valid only in
a limited range. The further you are away
from the point of correction, the larger the
position error will be. Keep in mind that
Selective Availability can cause position
errors up to 330 feet (100 m).
24
The map calibration function should NEVER
be used to attempt SA corrections. Any incorrect use of the calibration function can seriously affect the accuracy of your unit.
Note that geographic names and navaid text can’t be displayed simultaneously at range scales greater than 2 n.m. (4 km) and that navaid text is always
available in the review window by highlighting the navaid with the cursor.
Waypoint names and lat/lon labels cannot be displayed unless the waypoints
or lat/lon grid options have been selected. The lat/lon grid will always appear
in Overzoom and No Map modes, regardless of the configuration selection.
The map display configuration windows also feature a map calibration softkey to provide access to a user-defined map correction function. This function
allows you to calibrate the map display to match your exact physical position
(see left for Selective Availability warning) or correct data from older charts.
If your GPSMAP is not providing an accurate display of your position
(within the estimated position error noted on the Satellite Status Page), check to see
that your GPSMAP map datum matches the datum on the chart(s) you are
using (see Section 9 for selecting a map datum). To calibrate the map display,
you must know exactly where you are, and understand that the correction is
generally valid only in a limited range from the point of correction. You
should also only perform a map calibration when your boat is not moving.
The maximum correction is 16,400 feet (5000m). Note that all map calibration
offsets will stay in effect until they are cancelled!
To perform a map calibration from the map configuration window:
1. Press the MAP CAL softkey.
2. Use the K key to move the arrow cursor from the satellite position (indicated
by the satellite icon) to your exact position. The bearing, distance, and horizontal and vertical offset will be indicated at the top of the data window, with the
position coordinates indicated in the position field.
3. Press C to confirm the offset, and EXIT to return to the configuration window.
4. To cancel a map calibration offset, press the MAP CAL softkey. When the map
display appears, press the CLEAR softkey, followed by the EXIT softkey.

The GARMIN GPSMAP system stores over 1900 alphanumeric waypoints
with a user-defined icon and comment available for each waypoint. Waypoints
can be created, reviewed, moved or deleted right from the Map Page using the
target cursor to select positions and waypoints, and are managed through the
WAYPOINTS softkey. Once you are in the waypoint mode, you can also create,
edit and review waypoints through the waypoints list and the nearest
waypoints windows. Let’s cover the graphic waypoint functions first.
To create a waypoint from the map display:
1. Press the WAYPTS softkey. The target cursor will appear as an arrow pointer.
2. Use the K keypad to move the arrow cursor to the desired waypoint position.

The GARMIN GPSMAP system lets you create and store up to 20 reversible
routes with up to 50 waypoints each. Routes can be created and modified right
from the Map Page, allowing you to see each route graphically on-screen as
you create, review, modify or navigate the route. The GARMIN route system is
a powerful and extremely flexible system that you’ll want to master to get the
most out of your GPSMAP system.

Waypoint 1
(“active from” waypoint)
When a route is activated or inverted, it is copied into Route 0. The original route
remains intact in its original storage route.
Each route in the GPSMAP system has its own route number. Routes 1
through 19 are used as storage routes, with Route 0 always serving as the
active route you are navigating. When you activate a route, the storage route
you are activating is simply copied into Route 0, the active route.
This feature lets you modify your active route while you navigate, without
changing the storage route you activated. When you are finished navigating
the active route, simply delete Route 0 by pressing the DELETE softkey (you
still have the original route in storage) to stop navigating the active route. To
store a modified Active Route, copy Route 0 to an empty storage route.
Routes are broken down and navigated in
smaller segments called ‘legs’. The waypoint
you are going to in a leg is called the ‘active
to’ waypoint, and the waypoint immediately
behind you is called the ‘active from’
waypoint. The line connecting the ‘active to’
and ‘active from’ waypoint is referred to as
the ‘active leg’.
When a route is activated in the GPSMAP
system, the route leg closest to your position is
automatically selected as the ‘active leg’.

appearing as an arrow pointer. To add waypoints to the route, use the K keypad to move the arrow cursor to the desired position and press the C key.
HINT: Once the map display is in route creation mode, you can use the arrow
cursor to ‘snap to’ existing on-screen waypoints or navaids, or create new
waypoint positions. Existing waypoint positions will be added to the route without
confirmation. Whenever you are adding a new route waypoint not currently
stored in memory, you’ll be asked to save the new waypoint.
4. Press C to confirm the ‘OK’ prompt.
5. Once you’ve entered all the desired route waypoints, press the EXIT softkey.
The map display will now return to the map review mode, where you

Recording Interval defines the frequency with which the track plot is recorded:
Time– records track plot based upon a user-defined time interval.
Distance– records track plot based upon a user-defined distance between points.
Resolution– records track plot based upon a user-defined variance from your
course over the ground. This setting is recommended for the most efficient use
of track memory and TracBack performance. The distance value (entered in the

TracBack
Page 60
Start TracBack allows you to retrace your path using the track plot automatically
stored in the receiver’s memory. This eliminates the need to manually store waypoints along the way. A track plot is an electronic breadcrumb trail, showing the
path you have travelled. Your GPSMAP can be set to automatically record track
plot points any time the receiver is on and locked onto satellites (see page 59).
TracBack routes are created by reducing your track plot into a route of up to 50
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 plot point
stored in memory, so it’s a good idea to erase the track memory at the beginning of
your current trip (e.g., at the dock), before you get started (see page 59).
To create and activate a TracBack route:
1. Enable track plot recording and leave the GPSMAP on to automatically
record track log positions while underway (see page 59).
2. Select the Start TracBack option from the track recording submenu and
press C to create/activate the TracBack route. (A message box will appear
while the GPSMAP analyzes the data and creates the route.)
60
The TracBack route will contain waypoints (labeled ‘T###’, e.g. ‘T001’) which
mark the most significant features of the original track plot 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 plot at the point you wish to return to (ramp, dock, etc.)
• The Recording Status must be set to ‘Wrap’ or ‘Fill’.
• There must be at least two track plot points stored in memory to create a route.
• If the Recording Interval is set to ‘Time’ or ‘Distance’, the route may not closely
follow your path. Use ‘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.

Reading through the entire installation section before starting your installation will
help you get the most out of your GARMIN navigation system. An improper or poorly
planned installation can affect the GPS receiver’s accuracy, overall performance
and your ability to satisfactorily use the GPSMAP system.
WARNING!
The GPSMAP system has no user-serviceable
parts, and you should never attempt any
repairs yourself. The unit is gasket-sealed to
prevent moisture penetration. Opening the
case or loosening any fittings may expose
internal components to moisture and will
void the manufacturer’s warranty!
For warranty and service details, see page iii
at the front of this manual.

Installation
CAUTION!
Cutting or modifying the antenna(s)
may result in undesired operation
of the GPS. If the standard cable is
not long enough for your application, see your dealer for the proper
GARMIN cable extension. When in
doubt, seek the assistance of a
qualified installation technician.
66
To begin installation, you’ll need to select a suitable mounting position for
the antenna(s) and the GPSMAP unit. Once you’ve identified the best mounting
locations for your application, install the antenna(s) and its cable(s) first, then
the unit and power/data cable.
Mounting the antenna(s)
The GPS antenna should be mounted in a location that has a clear,
unobstructed view of the sky in all directions to ensure the best reception in all
conditions. Avoid mounting the antenna where it will be shaded by the boat’s
superstructure, a radome antenna, or mast.
The beacon antenna provides more flexibility in mounting locations.
Mounting near objects which partially shade its field of view is not a critical
concern, however large metal objects may create enough obstruction to degrade
reception and performance. As a general rule, mount the antenna at least 3 feet.
from all other antennas and the vessel’s alternator/ignition system components. A
ground strap is attached to the antenna coupler, except on the GA 23 H-field
antenna. For proper operation, the ground strap must be connected to a vessel (earth)
ground. Do not ground the coupler to the electrical system.
GARMIN antennas screw directly onto any standard 1” x 14 thread antenna
mount. If you need to raise an antenna to avoid shading, try using a 1” x 14
thread extension mast available at most marine dealers.
To install the antenna(s):
1. Screw the antenna directly onto the 1” x 14 thread mount.
2. Route the cable to the mounting location of the display unit, using the appropriate tie-wraps, escutcheon plates and sealant to secure the cable along the route
and through any bulkhead or deck.
3. Once the GPSMAP unit has been installed, connect the cable to the antenna
connector on the back of the unit. Make sure that you turn the antenna 1/4 turn
clockwise to lock the cable into place. (For models purchased with built-in
DGPS, connect each antenna cable to the Antenna Combiner. Then use the supplied short cable to connect the Antenna Combiner to the back of the unit.)

Antenna connection for GPSMAP system without built-in DGPS:
GPSMAP systems without the built-in DGPS beacon receiver do not include
the antenna combiner and antenna coupler. The GPS antenna is connected
directly to the BNC connector on the back of the unit. DGPS capability can be
added, as an option, by purchasing an external beacon receiver—such as
GARMIN’s GBR 21/23.
Connections to an external beacon receiver are made using the NMEA IN,
NMEA OUT (for GBR 21/23 only) and GROUND connections on the supplied
power/data cable. See the beacon receiver owner’s manual for connection
information not covered in the above diagram.
A second 1” x 14 thread antenna mount is needed
when installing a GPSMAP with built-in DGPS
beacon receiver. The second mount is used for the
antenna coupler and whip antenna.
Connect the antenna coupler’s ground strap to a vessel
(earth) ground. An earth ground connection can
usually be made by connecting to a thru-hull fitting,
engine block, dynaplate or body of a metal vehicle.
Note: The GA 23 H-field antenna does not require
grounding.

Installation
Mounting the GPSMAP unit
The GARMIN GPSMAP’s fully gasketed and sealed case is suitable for mounting in exposed locations or at the nav station. The unit comes with a gimbal
bracket that can be used for surface or overhead mounting. When choosing a
location for the display unit, make sure you consider the following conditions:
• There should be at least 3.25” (8.25 cm) clearance behind the case to
allow connection of the antenna and power/data cables.
• Provide adequate clearance for the G-chart cartridge cover to swing
open freely. You may swivel the unit to get a firm grip on the cartridge.
• The mounting surface should be heavy enough to support the unit and
protect it from excessive vibration and shock.
• The GPSMAP 215 screen will provide crisp contrast in most lighting
conditions, even in full sunlight. Because of the technology used in TFT
screens, the GPSMAP 225 performs best in shaded conditions, protected from direct sunlight.
WARNING!
The temperature range for GPSMAP units
is from -4 to +158ºF (-20- 70ºC). Extended
exposure to temperatures exceeding this range
(in storage or operating conditions) may cause
failure of the LCD screen. This type of failure
and related consequences ARE NOT covered
by the manufacturer’s warranty.
68
To install the GPSMAP unit:
1. Place the mounting bracket in the desired location.
2. Mark and drill the four mounting holes for the fasteners you are using.
3. Fasten the bracket to the surface using the appropriate fasteners.
4. Insert the GPSMAP into the mounting bracket. The bracket is designed for a
tight fit to provide additional support when swiveling the unit.
5. Screw the two mounting knobs through the bracket and into the display case.
6. Connect the power/data and antenna cables to the back of the unit, making
sure the locking rings are fully tightened on both connectors.

A simple way to determine your local time
offset is how many hours you are behind
or ahead of UTC (also called ‘Greenwich’
or ‘zulu’ time).
Example: EST(Eastern Standard Time) is
5 hours behind UTC, so your offset would
be -5. Adding one hour for daylight
savings would make EDT(Eastern
Daylight Time) -4. Subtract an hour for
each time zone as you travel west.
Offsets for Continental U.S. would be:

Almanac Data—Satellite constellation information (including location and health of
satellites) that is transmitted to your receiver from every GPS satellite. Almanac data
must be acquired before GPS navigation can begin.
Bearing—The compass direction from your position to a destination.
APPENDIX
Glossary
SECTION
G
Course Over Ground (COG)—Direction of movement relative to a ground position.
Crosstrack Error (XTK)—The distance you are off a desired course in either
direction.
Desired Track (DTK)—The compass course between the ‘from’ and ‘to’ waypoints.
Differential GPS (DGPS)—An extension of the GPS system that uses land-based
radio beacons to transmit position corrections to GPS receivers.
Estimated Time of Arrival (ETA)—The time of day of your arrival at a destination.
Estimated Time Enroute (ETE)—The time left to your destination at your present
speed.
Grid—A coordinate system that projects the earth on a flat surface, using square zones
for position measurements.
Ground Speed—The velocity you are travelling relative to a ground position.
Latitude—A north/south measurement of position perpendicular to the earth’s
polar axis.
Longitude—An east/west measurement of position in relation to the Prime Meridian,
an imaginary circle that passes through the north and south poles.
Position—An exact, unique location based on a geographic coordinate system.

Turn (TRN)— The difference and direction in degrees between the bearing to your
destination and your course over ground. The TRN value is used to indicate what
direction and how many degrees to turn to get back on course.
Universal Time Coordinated (UTC)— The time of day at the prime meridian
(0º longitude) in Greenwich, England.
Universal Transverse Mercator- (UTM)— A grid coordinate system that projects
global sections onto a flat surface to measure position in specific zones.
Velocity Made Good (VMG)—The speed you are closing in on a destination along a
desired course.

Loran TD System
LORAN C is a radio navigation aid operated and maintained in the United States
by the United States Coast Guard. The name LORAN is an acronym for "LOng
RAnge Navigation". The LORAN system covers the entire United States and the
U.S. Coastal Confluence Zone. From the perspective of a mariner, the system is
used for ocean and coastal navigation. It can be used as a supplemental system for
harbor and harbor approach navigation, and it is used for inland navigation by
recreational vehicles.

Loran TDs
LORAN TD Feature
The LORAN TD(Time Delay) feature eases the transition from using LORAN to
using GPS. The GPSMAP unit automatically converts GPS coordinates to LORAN
TDs for those who have a collection of LORAN fixes for favorite fishing spots and
other waypoints recorded as TDs. You can display your position as a TD or enter
waypoints as TDs. The accuracy to be expected from this conversion is approximately thirty meters. When the unit is placed in the LORAN TD format mode, it
simulates the operation of a LORAN receiver. Position coordinates may be
displayed as TDs, and all navigation functions may be used as if the unit were
actually receiving LORAN signals.
Using the LORAN TD Format
When creating new waypoints using LORAN TD coordinates you must set the
correct LORAN chain number and secondary stations in the Setup TD field before
storing the waypoint. After the waypoint is stored in unit memory, it will always
reference the LORAN chain number and secondary stations currently selected in
the Setup TD field. If you enter a different LORAN chain number, change the
secondary stations or offsets in the Setup TD field, the active waypoint

information will reflect those changes. Since the GPSMAP unit does not rely on
the LORAN signal for navigation, it can reference a different GRI chain and/or
secondary stations and still navigate to the location stored in memory.
The LORAN Position Format field is located in the Navigation Setup Menu. After
the 'LORAN TD' format is selected, a new option will appear over the M key
called 'Setup TD'. The 'LORAN Setup' page contains the fields where the
LORAN GRI-Chain Number, Primary & Secondary Stations and TD Offsets are
selected.
To change the “Setup TD” settings:
1. Press the M under SETUP TD.
2. Use the K key to select the field to change and press C.
3. Use the K key to highlight the new setting and press C.
4. When done, press the M key under the word EXIT to exit.

If the active GRI Chain, secondary stations or offsets have been changed since the waypoint
was created, the waypoint will now reference the active GRI-chain and secondary stations
and the TD coordinates will be adjusted accordingly. Remember that the GPS is not relying on
the LORAN signal for navigation and actually converts the TD coordinate to a useful LAT/LON
coordinate (in the background) before storing the waypoint in unit memory or using it for
navigation. Because of this the unit can navigate to a TD coordinate anywhere in the world.
