Getting Started
Initializing the Receiver
The GPS 152’s keypad system is designed to allow for fast, convenient selection of navigation
options and data entry. The Getting Started Tour will introduce you to the keypad and provide a
‘hands-on’ lesson in using the GPS 152.
The GPS 152 Quick Reference Guide contains helpful tips on using the unit and performing
various navigation tasks. It’s a good idea to keep the Quick Reference Guide nearby whenever you’re
operating your new GPS 152.
Initializing the Receiver
GPS 152 Self-Test Screen
The first time you power up your new GPS 152, the receiver must be given an opportunity to
collect satellite data and establish its present position. To ensure proper initialization, the GPS 152 is
shipped from the factory in AutoLocate mode, which will allow the receiver to “find itself” anywhere in
the world. To speed up the initialization process, we recommend using the graphic initialization process
described on the next page, which will usually provide a position fix within a few minutes.
Before you initialize, make sure the GPS 152 unit and antenna have been correctly installed on
your vessel according to the instructions in Appendix G. The antenna needs to be in a clear and
unobstructed view of the sky to receive satellite signals.
GPS 152 Warning Screen
To turn the GPS 152 on:
1. Press and hold the POWER key until the power tone sounds and the display comes on, then
release the POWER key.
The welcome page will appear while the unit conducts a self-test. Once the internal test is
complete, a warning page will appear, asking you to read and acknowledge important information
regarding the proper use of the unit.
To acknowledge the warning:
4
The satellite status screen displays until you
press QUIT or ENTER or a fix is acquired.
1. After reading the warning, press the ENTER/MARK key if you agree.
To graphically initialize the GPS 152:
1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until
the ‘GPS’ tab is highlighted, then press the MENU key once.
Getting Started
Initializing the Receiver
2. Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER/MARK to initialize
the receiver from the map. The Initialize Position Page will appear, prompting you to select your
approximate location with the map cursor.
3. Use the ARROW KEYPAD to move the map cursor and point to your approximate location within
200 miles. If you have difficulty identifying your position, press and release the IN key to zoom in
to see the next lower map scale.
4. Once you have determined your approximate location on the map, press the ENTER/MARK key.
I
This does not “calibrate” the unit in any way, but rather helps to speed up the initial
satellite acquisition. If the unit switches to the Map Page or displays ‘2D’ or ‘3D
Navigation’ during this process, it is not necessary to initialize the unit.
Point to your approximate location
and press ENTER/MARK.
The GPS 152 will now begin searching for the appropriate satellites for your region and should
acquire a fix within a few minutes. When viewing the ‘GPS’ tab on the Main Menu, a signal strength
bar for each satellite in view will appear on the top middle of the page, with the appropriate satellite
number under 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 indicated satellite(s) and is collecting data.
A satellite’s strength bar will turn
black when it’s ready for use.
• Solid signal strength bars— the receiver has collected the necessary data and the satellite(s) are
ready for use.
Once the receiver has collected information from at least three satellites, the top of the screen will
display either “2D or 3D Navigation”, and the GPS 152 is ready for use.
A Lost Satellite message appears on any
screen if the navigation signal is lost.

Getting Started
Power On/Screen Contrast
GPS 152 Getting Started Tour
The GARMIN GPS 152 is a powerful electronic navigation system that provides convenient control
of many advanced features right from the screen display. This tour is designed to take you through
the basic pages and functions of the system using the simulator mode. 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.
The Getting Started tour assumes that the receiver has been properly installed and initialized, and
you have not changed any of the default unit 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.
To turn the GPS 152 on:
1. Press and hold the POWER key until the power tone sounds, then release the POWER key. The
Welcome Page will appear while the unit conducts a self-test.
2. Once the self-test is complete, press the ENTER/MARK key, if you agree, to acknowledge the
warning.
The Map Page will appear as the receiver begins acquiring satellites. From the Map Page or any
other page, you may also adjust the screen contrast and backlighting.
To adjust the screen contrast:
To adjust the screen contrast,
press LEFT or RIGHT on the
ARROW KEYPAD to move
the contrast slider.

1. Press POWER and the Light and Contrast window will appear.
2. To decrease or increase the screen contrast, press left or right on the ARROW KEYPAD.
3. Press the ENTER/MARK key to finish.
The GPS 152’s adjustable screen backlighting is controlled with the POWER key, and may be
adjusted at any time from any page. The backlight can cycle through off, user-defined, and maximum
backlight levels by repeatedly pressing the POWER key.
To turn on and adjust the backlighting:
1. Press POWER and the Light and Contrast window will appear.
2. Press POWER again and the user-defined level of backlighting will activate. You may adjust this
level by pressing UP or DOWN on the ARROW KEYPAD. If you press POWER one more time, the
backlighting will be at the maximum setting.
Getting Started
Backlighting/
Simulator Mode
3. Press ENTER/MARK or QUIT when done.
The backlight will now cycle through off, the user-defined, and maximum backlight levels by
repeatedly pressing the POWER key.
Each page and the Main Menu of the GPS 152’s system also feature menu options, which gives you
access to other functions and features that relate to the screen you are viewing. To get a feel for how the
option menus work, let’s put the GPS 152 into simulator mode.
To place the GPS 152 in simulator mode:
Press UP or DOWN on the
ARROW KEYPAD to move
the backlighting slider up for
brighter or down for dimmer
backlighting.
1. From any page, press the MENU key twice. The Main Menu will appear, displaying a tab style list
of options and functions.
2. Use the ARROW KEYPAD to highlight the ‘Sys’ (System) tab, then press RIGHT then DOWN until
the field below the word ‘System Mode’ is highlighted and press ENTER/MARK.
3. Highlight ‘Simulator’ and press ENTER/MARK. Press ENTER/MARK again to confirm the ‘Running
Simulator’ message that appears at the bottom of the display.
Once the simulator has been started, the lower left corner will display a ‘S’ in a box on the main
pages to show “Simulating Navigation” status. Now you’re ready to continue the rest of the simulated
tour. Keep in mind that the GPS 152 does not track satellites in simulator mode, and this
mode should never be used for actual navigation. All the waypoint and route planning done in
simulator mode will still be retained in memory for future use.
When the unit is in simulator mode,
an ‘S’ will appear in the lower left
corner of every screen to show “Simulating Navigation.”

The GPS 152’s Map Page combines trackplotting with a user-selectable display of navigation data. It
will also be the page you use most to create and edit waypoints and routes. Before we take off on our
practice route, let’s take a brief look at its various features and displays.
The map display shows your “boat” as a triangle marker. City names (Larger than 200,000
population), marine markers and buoys (for the Americas only, preloaded from the factory) are also
shown. Additionally, it displays your track, routes and nearby waypoints. An on-screen cursor lets you
pan to other map areas, determine the range and bearing to a position, and perform various waypoint
and route functions.
The data window, located on the right side of the page, provides a user-selectable display of
various navigation data, including course, speed over ground, and bearing and distance to a particular
waypoint. The current map scale setting is located at the bottom right of the map window.
Getting Started
Using the Map Cursor
Working from 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 to pan to
other map locations, mark and edit waypoints and routes, and review position data of on-screen map
items and waypoints.
Map Cursor
To get a feel for using the Map Page and using the cursor, try the following exercise:
1. Use the IN/OUT keys to set the map scale to the 50 nm setting. Your boat should be near the center
of the map, at the receiver’s last known position. (If your boat isn’t where it should be, make sure
that you have initialized the receiver and acquired a position as described on pages 1-2.)
2. Use the ARROW KEYPAD to move the cursor. Notice how another data field appears at the
top of the page, showing the bearing and distance from your boat to the cursor, along with the
latitude/longitude of the cursor.
Current position
Map Scale
3. Press the QUIT key to remove the cursor and re-center your boat on the map display.
As you become more familiar with the cursor, you’ll see that the map display actively scrolls or
‘pans’, letting you explore areas around the world and create waypoints and routes. Wherever you
move the cursor, you’ll always be just one QUIT keystroke away from returning the map to your
present position.
Now that you’ve seen how the GPS tab and Map Page can be used to monitor satellite acquisition
and your present location, let’s take a minute to learn how to mark and store your present position as
a waypoint. (Since you’re in simulator mode, the present position displayed will be the last position
calculated by the receiver, which should be the spot where you’ve initialized the unit.) This will also
give you an opportunity to see how the GPS 152’s keypad and ENTER/MARK key are used for data
entry and changing the waypoint name and symbol.

Getting Started
Going to a Destination
GPS is all about marking positions as waypoints and navigating to them using the receiver’s steering
guidance and map displays. We’ve already seen how to use the ENTER/MARK key to store our present
position, so it’s time to move on to the fun part—going to a destination.
The NAV/MOB key, located on the left side of the keypad below the PAGE key, is the primary
tool used to select a destination waypoint, TracBack, or a route to navigate. The NAV/MOB key can
be used in three primary ways:
• Pressing NAV/MOB once displays a list of options from which you can select ‘Go To Waypoint’,
‘Follow Route’, ‘Follow Track’, or ‘Stop Navigation’.
• Holding down NAV/MOB, or pressing the key 2 times, activates the MOB (Man OverBoard) feature.
This marks the point at which the MOB was activated as a waypoint named “MOB” and also
establishes it as an active “Go To” point.
• Highlighting an on-screen waypoint or map item as a destination directly from the Map Page and
pressing NAV/MOB allows you to graphically select points to “Go To”.

1. Press NAV/MOB. The option list page will appear. (If we were selecting a single waypoint to navigate
to rather than a route, we could highlight the waypoint on the map, press NAV/MOB and then
press ENTER/MARK.)
2. Use the ARROW KEYPAD to highlight the ‘Follow Route’ option. Press ENTER/MARK to confirm.
3. The Select Route page will appear, with the ‘GPS TOUR’ route highlighted.
4. Press ENTER/MARK then highlight ‘Activate’ and press ENTER/MARK again.
To get a better view of what’s going on, zoom in to a closer map scale.
1. Repeatedly press the IN key until you select the 5 nm scale.
You can also Invert a route to follow
it in reverse.
Note: You may also hold the IN or OUT keys down to quickly scroll through the map scales. The
Map Page should now display the first three waypoints chained together in a simple route, with your
boat at the first route waypoint.
A data field at the top of the page will now display the speed, distance to the second route waypoint,
and a pointer which shows you which way to go. To get started, let’s enter a speed for our vessel, which
we can do from the Main Menu Page.
To enter a boat speed:
1. Press the MENU key twice to display the Main Menu Page.
2. Use the ARROW KEYPAD to highlight the ‘Sys’ tab, then press RIGHT, UP, then RIGHT until the ‘Set

5. Press ENTER/MARK to finish, and QUIT until you return to the Map Page.
Once a speed has been entered, you’ll notice that the map will automatically begin to move slowly,
keeping your boat centered on the display. The direction of movement, also called ‘track’, will be
controlled by the simulator.
You’ll now have a clearer picture of the route you are navigating. Press the IN key to zoom in to the
2 nm scale. Now that you’ve zoomed in a little closer to your route, you can pan ahead of your vessel
with the cursor to review map items and create on-screen waypoints. Try moving the cursor to highlight
the ‘TOUR3’ waypoint— just use the ARROW KEYPAD to move the cursor as close as possible to the
waypoint. (To move the cursor in small increments, try a series of short key presses.)
Once the cursor is over the TOUR3 waypoint, you’ll notice that the waypoint symbol and name will
become highlighted. The data field at the top of the page will display the waypoint name, the range and
bearing from your present position, and the coordinates for the waypoint.

Now that we’re navigating to an actual destination, let’s move on to the GPS 152 navigation pages
by pressing the PAGE key.
The GPS 152 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 next waypoint as well as the pointer to the next waypoint are
displayed on the right side 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. When you
are not navigating to a waypoint, the compass will show your direction of travel as you move but
the arrow will not appear.
Let’s move on to the Highway page by pressing the PAGE key.

Zoom Scale
The GPS 152’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 steer toward the center of the highway or “keep it on the road”. The four default data fields on
the right side of the page indicate speed and distance to the next destination (or the next waypoint in
a route), along with a pointer arrow which points the next waypoint and the compass track you are
heading. Use the Highway Page as your primary navigation page (in lieu of the Compass Page) when
your main concern is following a defined course.
If you get off course, the highway will move to give you graphic guidance to get back on course.
You can zoom in or out on the Highway display for a smaller or larger view. Five available settings
range from 1X to 16X, with a default setting of 8X. The current scale will appear in the bottom
right of the display.

The GPS 152’s Map Page provides a display of plotting and navigational data. The unit is preloaded
from the factory with a worldwide database of cities greater than 200,000 in population and marine
navaids, for the Americas only. 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.
When the cursor is active, an additional data window will appear below the data fields to indicate
the position, range and bearing to the cursor or a selected waypoint or map item. The map scale displays
at the bottom right of the map window.
The IN and OUT keys, combined with the ARROW KEYPAD, let you select zoom ranges and move
the cursor. Two basic map operating modes, position mode and cursor mode, determine what is shown
on the map display. Position mode pans the map to keep the present position marker within the display
area, while cursor mode pans the map to keep the cursor within the display area.
The GPS system will always power up in the position mode, with your vessel centered on the
map display.
When the ARROW KEYPAD is pressed, the GPS 152 will enter cursor mode. In cursor mode:
• The cursor can be moved over the map display using the ARROW 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 will change as the boat’s position changes.
• Whenever you zoom in cursor mode, the cursor will be centered on screen.
• To return to position mode, press the QUIT key.

Compass Page
The GPS 152 features two different navigation pages: Compass and Highway. Whenever a NAV/
MOB, Follow Track (TracBack) or Follow Route have been activated, the GPS 152’s Compass Page will
guide you to your destination with digital readouts and a graphic compass display, which includes
a bearing pointer. Use this page (instead of the Highway Page) when travelling at slower speeds,
when making frequent directional changes, or where straight-line 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.

Creating Waypoints
Creating and Using Waypoints
The GARMIN GPS 152 stores up to 500 alphanumeric waypoints with a user-defined icon and
depth available for each waypoint. Waypoints can be created using three basic methods:
• ENTER/MARK key– used primarily for marking your present position, the ENTER/MARK key also
provides options that allow you to select a map position or map item from the map display.
• Graphically– allows you to define a new waypoint position from the map display using the ARROW
KEYPAD.
• Text Entry– allows you to enter a new waypoint’s position coordinates manually (from a chart, etc.).
ENTER/MARK Key
Press ENTER/MARK to use the
default name and symbol.
The GARMIN GPS 152’s ENTER/MARK key lets you quickly capture your present position— or
cursor or map item position— in order to create a new waypoint. You must have a valid position (2D or
3D) fix to mark your present position. This can be determined by looking at the GPS Main Menu tab.
When you move the cursor over a map item, you will see a highlighted description of that item.
To mark your present position:
1. Press and hold the ENTER/MARK key until the ‘New Waypoint’ window appears then release it.
You will see a default three-digit name and symbol for the new waypoint.
2. To accept the waypoint with the default name and symbol, press ENTER/MARK to confirm the
highlighted ‘OK’ prompt.
3. To enter a different name, highlight the name field and press the ENTER/MARK key, then use the
ARROW KEYPAD to enter the new letter/numbers and press ENTER/MARK when done. Note: You
may use up to 10 alphanumeric characters for the name.
Highlight a field and press ENTER/
MARK to enter a new symbol, name
or depth.
28
4. To enter a different symbol, highlight the symbol field to the left of the name and press the
ENTER/MARK key, then use the ARROW KEYPAD to highlight the new symbol and press
ENTER/MARK.
5. To enter an optional depth, highlight the “Depth” field to the right of the position coordinates
and press the ENTER/MARK key, then use the ARROW KEYPAD to enter a value and press
ENTER/MARK. If you are receiving valid sonar NMEA input (pg. 79) , the depth field will
automatically fill in. Otherwise, you must manually enter a depth.

Creating Waypoints
6. When done, use the ARROW KEYPAD to highlight the ‘OK’ prompt and press ENTER/MARK to
save the waypoint into memory.
Creating Waypoints Graphically
Waypoints may also be quickly created from the map display, which allows you to ‘point and shoot’
at any map position to create a new waypoint. To mark a map item, select the desired map item with
the cursor. The GPS 152 will use the map item text shown on the cartography as the default name.
When selecting a map item, the option ‘Create Waypoint’ will appear in addition to a description of that
point and its distance and bearing from your current position.
Map waypoint from non-map item.
To create a new waypoint graphically:
1. Use the ARROW KEYPAD to move the cursor to the desired map position. If you want to create the
new waypoint at an on-screen map item, highlight the map item on the map display.
2. Press the ENTER/MARK key.
If you are not using a map item to create a waypoint, go to step 4.
3. Highlight ‘Create Waypoint’ or ‘OK’ and press the ENTER/MARK key.
4. To accept the waypoint with the default name and symbol, press ENTER/MARK. If you are creating
a waypoint from an on-screen map item, the name and symbol will automatically reflect the
selected map item’s name and symbol.
5. To change the name, symbol or enter a depth, highlight the appropriate field and press
ENTER/MARK. Make your changes and press ENTER/MARK when done.
6. After entering and confirming your changes, move the field highlight back to the ‘OK’ prompt and
press ENTER/MARK.

Going to a Destination
Going to a Destination
Using the NAV/MOB key, the GPS 152 provides four ways to navigate to a destination: Go To
Waypoint, Follow Route, Follow Track (TracBack), and MOB (Man OverBoard) navigation. Once you
are actively navigating, you will see a straight line that always runs from your current location to the
destination. The easiest method for selecting a destination is the ‘Go To’ function, which lets you
select a destination waypoint and quickly sets a direct course from your present position. If you have
a waypoint highlighted on a list or the map, ‘Go To <waypoint name>’ will appear in addition to
‘Go To Waypoint’. The ‘Go To’ function can be accessed from a list of waypoints or graphically from
the map display.
To activate a ‘Go To’ from the waypoint list:
1. Press the NAV/MOB key.
2. Use the ARROW KEYPAD to highlight ‘Go To Waypoint’ and press ENTER/MARK.
Choose from a waypoint from either
the ‘By Name’ or ‘Nearest’ tab list.
3. To select a waypoint from the waypoint lists, use the ARROW KEYPAD to highlight either the ‘By
Name’ or ‘Nearest’ tab, select a waypoint and press ENTER/MARK.
To select a waypoint from the map, highlight either the ‘By Name’ or ‘Nearest’ tab and press
MENU. With ‘Select From Map’ highlighted, press ENTER/MARK. Use the zoom IN and OUT
buttons and the ARROW KEYPAD to select a waypoint, then press ENTER/MARK.
36
Selecting a ‘Go To’ Graphically
A graphical ‘Go To’ may be used to select one of three items from the map display: an existing
waypoint, an on-screen map item (roads, rivers, cities, navaids, etc..), or a new map point (non-map
item). If you are selecting a map item as the ‘Go To’ destination, the GPS 152 will automatically use
the name of the map item, but the point will not be stored in the waypoint list. See page 29 for
creating waypoints using map items. If you are selecting a new map point (non-map item) as the
‘Go To’ destination, the GPS 152 will automatically create or move a waypoint named ‘MAP’ at the
cursor position.
Reference
Going to a Destination
To activate an existing waypoint or map item as a ‘Go To’ from the map display:
1. Use the ARROW KEYPAD to highlight the waypoint or map item on screen and press NAV/MOB.

TracBack Navigation
TracBack Navigation (Follow Track)
The second method of navigating to a destination is by using the TracBack feature. The TracBack
function allows you to retrace your path using the track log automatically stored in the receiver’s
memory, which will eliminate the need to store waypoints along the way. TracBack routes are created
by reducing your track log into a route of up to 30 turns and activating an inverted route along those
points. Once activated, a TracBack route will lead you back to the oldest stored track log point, so it’s
good idea to clear the existing track log at the start of your current trip before you get started.
To clear the track log and define a starting point for a TracBack route:
1. Press the MENU key twice to display the Main Menu page.
2. Using the ARROW KEYPAD, highlight the ‘Trk’ tab, then highlight the ‘Active’ tab to the right.
Trk (Track) Tab
3. Press the MENU key, then use the ARROW KEYPAD to select the ‘Clear’ option and press

4. Highlight the ‘OK’ field and press ENTER/MARK.
You must first save the track log before you can use the ‘Follow Track’ feature. The Save feature
allows you to store a track log from certain times and dates.
To save a track log:
1. From the Main Menu, use the ARROW KEYPAD to highlight the ‘Trk’ tab, then highlight the
‘Active’ tab to the right.
2. Press the MENU key, then use the ARROW KEYPAD to select the ‘Save’ option and press

3. From the ‘Save Back Through’ window, highlight the desired time, date, or ‘Entire Log’ and press
ENTER/MARK.
4. Next, the track will begin saving and then display the ‘Saved Track’ window when done. The default
name, distance and number of points will be displayed. Highlight ‘OK’ and ENTER/MARK press
to save the track.

2. Highlight the track you wish to follow and press ENTER/MARK.
3. Choose either ‘Original’, which will navigate you from the end to the start of your trip, or ‘Reverse’,
which will navigate you from the start to the end of your trip and press ENTER/MARK.
Once a TracBack has been activated, the GPS 152 takes the track log currently stored in memory
and divides it into segments. Up to 30 temporary ‘turns’ are created, named BEGIN, Turn1, Turn2,
Turn3, etc. and END, to mark the most significant features of the track log, duplicating your exact path
as closely as possible. To get the most out of the TracBack feature, remember the following tips:
Default
Track
name
Total
number
of points
• Always clear the track log at the point that you want to go back to (dock, etc..).
• The ‘Record Mode’ option on the track log setup page must be set to ‘Fill’ or ‘Wrap’.
• There must be at least two track log points stored in memory to create a TracBack route.
Total
Distance
Check this box to
display track
• If the track log interval is set to the ‘Time’ option, the route may not follow your exact path (keep the
interval set to ‘resolution’ for best performance).
• If the receiver is turned off or satellite coverage is lost during your trip, the TracBack will draw a
straight line between any point where coverage was lost and where it resumed.
• If your track log’s changes in distance and direction are too complex, 30 waypoints may not mark
your path accurately. The receiver then assigns the 30 waypoints to the most significant points of
your track, and simplifies segments with fewer changes in direction.
To stop TracBack navigation:
1. Press the NAV/MOB key, highlight ‘Stop Navigation’ and press ENTER/MARK.
2. Choose either ‘Yes’ or ‘No’ and press ENTER/MARK to confirm.

As soon as the GPS 152 has collected the necessary data from the best satellites in view to calculate
a fix, the status field will indicate a 2D or 3D status. The unit will then update the position, date
and time.
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’,’2D Diff Navigation’,‘3D Navigation’, or ’3D
Diff Navigation’ in the status field). 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 (see figure to the
left). 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.
WAAS Capability
The GPS 152 is capable of receiving WAAS (Wide Area Augmentation System) satellite signals.
WAAS is an FAA (Federal Aviation Administration) funded project to improve the overall accuracy and
integrity of the GPS signal for aviation use, but land/sea based users may also benefit from this system.
At this time the system is still in the development stage and is not fully operational. There are currently
two WAAS satellites that can be received in the U.S.A., one over the Atlantic Ocean and one over the
Pacific Ocean, in a geo-stationary orbit over the equator. Effective use of the WAAS satellite signal may
be limited by your geographic location in relation to those satellites, now in developmental service.
WAAS satellite signal reception requires an absolute clear view of the sky and works best when there
are no nearby obstructions such as buildings, mountains, etc.. WAAs satellites will be numbered 33 or
higher when viewing the sky view on your GPS 152. Initial reception of the WAAS signal may take up
to 15-20 minutes, then 1-2 minutes afterwards. When WAAS differential correction has been received
for GPS satellites (numbers 32 or below), a ‘D’ will appear in the signal bar of the sky view and ‘2D
or 3D Diff Navigation’ will appear in the receiver status. To learn more about the WAAS system, its
satellite positions and current state of development, visit the FAA web site (http://gps.faa.gov). Since
WAAS requires CPU resources of the GPS 152 to search for and track the satellites, you may disable the
WAAS feature to improve unit performance if WAAS reception is not available in your area.

Receiver Status, Accuracy and DOP
Receiver status is indicated at the top field of the page, with the current Accuracy and Dilution Of
Precision (DOP) below the sky view. DOP is an indication of satellite geometry quality measured on a
scale of one to ten (lowest numbers the best, highest numbers the poorest). Accuracy uses DOP and
other factors to calculate horizontal position accuracy in feet or meters. The status field will show one
of the following conditions:
• Looking For Satellites— the receiver is looking for any satellites.
• AutoLocate— the receiver is looking for any satellite whose almanac has been collected. This
process can take up to five minutes.
• Acquiring Satellites— the receiver is looking for and collecting data from satellites visible at its last
known or initialized position, but has not collected enough data to calculate a fix.
• 2D Navigation— at least three satellites with good geometry have been acquired and a 2 dimensional

position fix (latitude and longitude) is being calculated. ‘2D Differential Navigation’ will appear
when you are receiving DGPS or WAAS corrections in 2D mode and a ‘D’ will show on the strength
bar of satellites being corrected.

The Differential SNR (Signal to Noise Ratio) indicates, on a scale to 0-30db with 30db being the
best, the strength of the DGPS signal being received. If no optional DGPS receiver is used with the
GPS 152, the ‘DGPS Rcvr’ field will display ‘Off’ and the ‘DGPS SNR’ field will be blank. The SNR
will depend upon the mounting of your DGPS receiver and the distance from the DGPS transmitting
station.

Appendix A
Loran TD
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 TD Feature
You may change to Loran TD from either the
Map Page or Units Tab on the Main Menu.
The LORAN TD (Time Delay) feature eases the transition from using LORAN to using GPS. The
GPS 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 was 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 GPS 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.
66
The LORAN Position Format field is located under the Units tab in the Main Menu. The ‘LORAN
TD Setup’ window contains the fields to select the Loran GRI-Chain Number, Primary and Secondary
Stations, and TD Offsets.
To setup Loran TD from the Main Menu:
1. Using the ARROW KEYPAD, highlight the “Units” tab and then the “Position Format” field press
ENTER/MARK.

3. When done, press the QUIT key to return to the Map Page.
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 adjust the
TD coordinates 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 to memory or using it for navigation. Because of this the unit can navigate to a
TD coordinate anywhere in the world.

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.

Antenna Installation
Installing the GPS 152
The GPS 152 must be properly installed according to the following instructions to get the
best possible performance. If you have the 152 with the built-in internal bail mount antenna
(010-00227-10), you may skip this section and proceed to the next page. For unit’s purchased with the
external GA 29 antenna (010-00227-00), follow the instructions below. To complete the installation,
you’ll need the appropriate fasteners and a 1” x 14-thread marine antenna mount available at most
marine dealers.
Mounting the GPS Antenna
The antenna should be mounted in a location that has a clear, unobstructed view of the sky in all
directions and as far away from interference as possible to ensure the best reception. Avoid mounting
the antenna where it will be shaded by the boat’s superstructure, a radome antenna, or mast. Sailboat
users should avoid mounting the antenna high on the mast to prevent inaccurate speed readings caused
by excessive heeling. Most marine VHF and LORAN antennas should not seriously degrade the GPS
antenna’s reception. It is a good idea to temporarily place the antenna and unit in the desired mounting
location and test any other nearby electronics to see if they interfere with the GPS unit. Never paint
the antenna or clean it with harsh solvents.
The GARMIN antenna screws directly onto any standard 1” x 14-thread antenna mount. If you
need to raise the antenna to avoid shading, try using a 1” x 14-thread extension mast available at
most marine dealers.
To install the GPS antenna:
It is possible to route the coaxial cable either through,
or outside the antenna mount. The BNC connector on
the coaxial cable can be removed, and the coaxial cable
shortened to ease installation. If the BNC connector is
removed it must be replaced with a new BNC connector.
76
1. Screw the antenna directly onto the 1” x 14-thread mount.
2. Route the cable to the mounting location of the display unit. Use the appropriate tie-wraps,
fasteners and sealant to secure the cable along the route and through any bulkhead or deck.
3. Once the GPS 152 unit has been installed, connect the cable to the antenna connector on the
back of the display unit. Make sure that you turn the antenna cable connector 1/4 turn clockwise
to lock the cable into place.
Mounting the GPS 152 Unit
The GPS 152’s compact, waterproof case is suitable for mounting in exposed locations or at the nav
station. The unit comes with a gimbal bracket and may be surface mounted or flush mounted. When
choosing a location for the display unit, make sure you consider the following conditions:
Appendix G
Unit Installation
• There should be at least a 3” (5 cm) clearance behind the case to allow connection of the
antenna (external antenna only), power/data cables.
• The mounting surface should be heavy enough to support the unit and protect it from excessive
vibration and shock.
• For unit’s with the built-in internal bail mount antenna (010-00227-10), it should be mounted in
a location that has the clearest, most unobstructed view of the sky in all directions to ensure the
best reception. Avoid mounting the unit where it will be blocked by the boat’s superstructure, a
radar arch, or mast.
I
The temperature range for the GPS 152 is 5°F to 158°F (-15°C to 70°C). 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 limited warranty.
To surface mount the GPS 152 unit:
1. Place the mounting bracket in the desired location.
2. Mark and drill the four mounting holes for the fastener you are using.
3. Fasten the bracket to the surface using the appropriate fastener.
4. Insert the GPS 152 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 (external antenna only) to the back of the unit, making
sure the locking rings are fully tightened on both connectors.
77
Appendix G
Unit Installation
The GPS 152 with external antenna (010-00227-00) can be flush mounted on a flat panel of
.08-.52” thickness using the cam lobe feature on its mounting bracket
To flush mount the GPS 152 unit:
1. Cut a 4.25”W x 4.25”H (108 x 108 mm) hole in the panel.
2. Place the GPS 152 into the hole from the front until the flange rests against the mounting surface.
3. From the back of the panel, loosely attach the bracket such that the slot in the ratchet area points
away from the mounting panel.
Figure 1
Pull bracket down until
cam lobe contacts surface.
4. Rotate the bracket downward until the panel is pinched tightly between the unit’s flange and
bracket lobe (figure 1).
5. Tighten the knobs and connect the power/data and antenna cables. Note: if the panel is too thick to
allow use of the supplied knobs, two M6 screws may be used to secure the bracket.
The International version of the GPS 152 (010-00227-20), with external antenna, can be flush
mounted on a flat panel using its existing mounting bracket.
To flush mount the International version GPS 152 unit:
1. Remove the four M5 screws from the back of the unit and remove the mounting bracket.
Figure 2
2. Using the mounting bracket as a template, outline the center relief hole and mark the location of
the four screw holes centers on your bulkhead or other surface (figure 2).
3. Cut the 2.75” (70 mm) relief hole from the panel and drill the four 0.20” (5.08 mm) screw holes.
4. Front the front, place the GPS 152 into the relief hole until it rests flush against the mounting
surface.
Figure 3
78
5. Secure the unit to the mounting surface using the M5 screws. For thick mounting surfaces, insert the
M5 screws directly thru the drilled holes (figure 3). For thin panels, place the mounting bracket on
the back side of the panel for more support. Connect the power/data and antenna cables.
Connecting the Power/Data
The power/data cable connects the GPS 152 to a 10-40 volt DC system and provides interface
capabilities for connecting external devices. The color code in the diagram below indicates the
appropriate harness connections. Replacement fuse is a AGC/3AG - 1.5 Amp fuse.
