• Lost or stolen unit tracking
The GPSMAP 176 uses GPS technology in order to find your
precise location. GPS stands for Global Positioning System, a
group of 24 satellites, circling the Earth twice a day, at an altitude
of about 12,000 miles. The satellites transmit very low power
radio signals containing position and time information, allowing
anyone with a GPS receiver to determine their location on the
Earth within 100 meters or better. For more detailed information
regarding GPS, we have prepared a booklet called “GPS Guide
for Beginners” which is available to you from our web site at
www.garmin.com.
GARMIN’s Product Support department can be reached Monday–Friday, 8 a.m. to 5 p.m. Central
Standard Time, by phone at 1-800-800-1020, or by e-mail at sales@garmin.com.

Introduction
Warnings and Cautions
WARNING: The GPS system is operated by the United States government, which is solely
responsible for its accuracy and maintenance. The system is subject to changes which could affect the
accuracy and performance of all GPS equipment. Although the GARMIN GPSMAP 176 is a precision
electronic NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted and, therefore,
become unsafe.
CAUTION: Use the GPSMAP 176 at your own risk. To reduce the risk of unsafe operation,
carefully review and understand all aspects of this Owner’s Manual—and thoroughly practice operation
using the simulator mode prior to actual use. When in actual use, carefully compare indications from
the GPSMAP 176 to all available navigation sources, including the information from other NAVAIDs,
visual sightings, charts, etc. For safety, always resolve any discrepancies before continuing navigation.
CAUTION: It is the user’s responsibility to use this product prudently. This product is intended to
be used only as a navigational aid and must not be used for any purpose requiring precise measurement
of direction, distance, location or topography.
NOTE: The electronic chart is an aid to navigation and is designed to facilitate the use of authorized
government charts, not replace them. Only official government charts and notices to mariners contain
all information needed for safe navigation – and, as always, the user is responsible for their prudent
use.
MAP DATA INFORMATION: One of the goals of GARMIN is to provide customers with the most
complete and accurate cartography that is available to us at a reasonable cost. We use a combination of
governmental and private data sources, which we identify as required in product literature and copyright messages displayed to the consumer. Virtually all data sources contain inaccurate or incomplete
data to some degree. This is particularly true outside the United States, where complete and accurate
digital data is either not available or prohibitively expensive.

This Reference Manual describes the Main Display pages and their options in detail. The Quick
Start Guide describes the basic functions of the GPSMAP 176 and the processes of navigating the Main
Display pages. While the Reference Manual will provide some direction on how to select an item, the
main purpose is to describe each Main Page and its Option Menu in detail.
Initializing the GPS Receiver
Reference
Initializing the GPS Receiver
Before the GPSMAP 176 can be used for GPS navigation, the GPS receiver must be initialized. The
GPS receiver only needs to be initialized the first time the unit is used, or if it has been stored for several
months. This process is automatic and should only take a few minutes.
The GPSMAP 176 stores orbital data for each satellite in an Almanac. The orbital data is supplied in
the satellite signals. Each time the unit receives satellite signals, the Almanac is updated. This is how
the GPSMAP 176 knows which satellites to search for. If you do not use the unit for several months, or
move the unit several hundred miles between uses, the Almanac can become “cold,” which means the
orbital data is no longer valid. If the Almanac is “cold,” your unit may take longer to lock on to satellites while it updates the Almanac with fresh data.
To initialize the GPS receiver:
1. With fresh batteries installed, take the unit outside where it will have an unobstructed view of the sky
and turn it on. Make sure the antenna is pointed up and not in the saved position.
GPS Information Page
2. The unit will search for satellite signals and begin to gather and save the information that it needs
to become operational. Following the screen prompts, press ENTER to display the GPS Information
page.
3. When the unit is able to navigate, the message ‘2D GPS Location’ or ‘3D GPS Location’ will be displayed at the top of the GPS Information page and/or the unit will automatically switch to the Map
Page.
If the unit is not able to gather the necessary satellite information, an options page will be displayed.
Select ‘New Location’ then ‘Automatic’ and allow the unit to continue initializing. This selection will
force the unit to search for all satellites and the unit may take a little longer to become operational using
this method.

Initializing the GPS Receiver
Initialization Options
If the GPSMAP 176 is unable to determine its location, an options menu will be displayed.
Depending on the situation, select the appropriate option to help the unit acquire satellites.
Start Simulator— This option will turn the GPS receiver Off. Select this option if you are indoors
and can not receive satellite signals, or if you wish to practice using the unit in simulator mode. This
options saves battery power and allows the map to redraw faster.
New Location— If you have moved to another state, province or country, and you are having
trouble locking on to satellites, select ‘New Location.’ Another menu will be displayed with the
options ‘Automatic’ or ‘Use Map.’ If ‘Automatic’ is selected, the unit switches to AutoLocate mode
and begins searching for satellites. If ‘Use Map’ is selected, use the pointer on the Map page to select
your approximate location and the unit will continue to acquire satellites normally. ‘Automatic’ may
take longer to acquire satellites.
Stored w/o Batteries— If you have stored the unit without batteries, the date stored in the GPS
may be incorrect. To check the date, highlight ‘Stored w/o Batteries’ and verify the date displayed
below the options menu. If the date is incorrect, select ‘Stored w/o Batteries’ and press ENTER to
search for satellites.
GPS Information Page Options
Continue Acquiring— Select this option if you are in an area where the satellites are temporarily
being blocked.
For more information on the GPS Information page, see pages 40-43.

Map Page
Reference
The GPSMAP 176’s Map Page provides a comprehensive display of electronic cartography, plotting
and navigational data. When using the unit with the optional BlueChart data or MapSource software, the map display shows your location on a digital chart, complete with geographic names, map
items, navaids 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.
Two basic map operating modes, position mode and cursor mode, determine what cartography is
shown on the map display. Position 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 176 will always power up in the position mode, with the last known location centered on the map display. When the ARROW KEYPAD is pressed, the GPSMAP 176 will enter cursor
mode.

When the cursor is active, an additional data window will appear at the top of the screen to indicate
the position, range and bearing to the cursor or a selected waypoint or map item.
Using the Cursor
The cursor allows you to pan away from your present position and scroll to other map areas around
the world (even outside of your current detail coverage). As you pan past the edge of the current map
display, the screen will actively scroll forward to provide continuous map coverage (keep in mind that
the boat icon will move with the scrolling map, and may not be visible on the display screen).

NOTE: When the cursor reaches the edge of the map, the unit may pause as it loads new
map data.

Map Page Cursor
As you move the cursor, the distance and bearing from your present position to the cursor will be
displayed in the data window, along with the cursor’s position coordinates. When you zoom in cursor
mode, the cursor will stay centered on the screen. When the cursor is stationary, a fixed coordinate
position will appear in the position field, and the distance and bearing from your present position will
change as your boat moves.
To eliminate the cursor and re-center your position on screen:
1. Press the QUIT key. The unit will return to position mode.
The cursor may also be used to ‘snap’ to on-screen waypoints and map items, allowing you to review
a selected position directly from the map display.
To select an on-screen waypoint or map item with the cursor:
1. Use the ARROW KEYPAD to move the cursor to the desired waypoint or map item (if there are
several waypoints grouped closely together, zoom in closer for a better view).

Data Card Information Screen and Options
Whenever a ‘Go To’, ‘Navigate Track’ (TracBack) or ‘Navigate Route’ have been activated, the
GPSMAP 176’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 and Using Waypoints
The GARMIN GPSMAP 176 stores up to 3000 alphanumeric waypoints with a user-defined icon,
comment, and depth available for each waypoint. Waypoints can be created using three basic methods:
• ENTER key— used primarily for marking your present position, the ENTER key also provides
options that allow you to select a map position or map item from the map display. You may also use
the ENTER key to create a waypoint projected from a user-defined position.
• 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.).
Reference
Creating Waypoints
Marking Your Present Position
The GARMIN GPSMAP 176’s ENTER key lets you quickly capture your present position to create a

Going to a Destination
Going to a Destination
Using the NAV key, the GPSMAP 176 provides four ways to navigate to a destination: Go To Point,
Navigate Route, Navigate 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 on the Map page. The easiest method is the ‘Go To’ function, which lets you select a destination
point and quickly sets a direct course from your present position. If you have a point highlighted on a
list or on the map and press NAV, ‘Go To <point name>’ will appear in addition to ‘Go To Point’. The
‘Go To’ function can be accessed from any list of points or graphically from the map display.
To activate a ‘Go To’ from the points list:
1. Press the NAV key.
2. Use the ARROW KEYPAD to highlight ‘Go To Point’ and press ENTER.
3. From the ‘Find’ menu, highlight ‘Waypoints’ and press ENTER. (You may also choose to go to other
points, such as Cities, Tide Stations, etc. from this list.)
Choose a waypoint from either the ‘By Name’ or ‘Nearest’ tab list.
4. Select a waypoint from the ‘By Name’ or ‘Nearest’ list then press ENTER. This will display the
Waypoint Review Page.
5. With the ‘Go To’ button highlighted, press ENTER to begin navigation.
To stop navigation:
1. Press the NAV key.
2. Use the ARROW KEYPAD to highlight ‘Stop Navigation’ and press ENTER.
Selecting a ‘Go To’ Graphically
The waypoint or map item name will automatically appear
when highlighted and NAV is pressed.
26
190-00185-10_0A.indd 26
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 GPSMAP 176 will automatically
use the name of the map item, but the point will not be stored in the waypoint list. See page 18 for
creating waypoints using map items. If you are selecting a new map point (non-map item) as the ‘Go
To’ destination, the GPSMAP 176 will automatically create or move a waypoint named ‘MAP’ at the
cursor position.
6/18/2002, 10:00:37 AM
To activate an existing waypoint or map item as a ‘Go To’ from the map display:

TracBack Navigation (Navigate Track)
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 50 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 a good idea to clear the existing track log before you start of your current trip.
‘Go To MAP Point’ allows you to navigate to a spot on the map
which is not a waypoint or map item.
To clear the track log and define a starting point for a TracBack route:
1. Press MENU twice to display the Main Menu page.
2. Using the ARROW KEYPAD, highlight the ‘Track’ tab, then highlight the ‘Active’ tab to the right.
3. Use the ARROW KEYPAD to select the ‘Clear’ button and press ENTER.
4. Highlight the ‘OK’ field and press ENTER. Press QUIT to exit.
You must first save the track log before you can use the ‘Navigate Track’ feature. The Save feature

which will navigate you from the end to the start of your trip (TracBack) and press ENTER.
You must first save a track before using the ‘Navigate Track’
option. If there are no saved tracks, the ‘Navigate Track’ option
will be disabled.
Once a TracBack has been activated, the GPSMAP 176 will take the track currently stored in
memory and divide it into segments called ‘legs’. Up to 50 temporary ‘turns’ will be created to mark the
most significant features of the track in order to duplicate your exact path as closely as possible. To get
the most out of the TracBack feature, remember these Navigating tips:
• 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’.
28
190-00185-10_0A.indd 28
6/18/2002, 10:00:39 AM
• There must be at least two track log points stored in memory to create a TracBack route.
• If the track log interval is set to the ‘Time’ option, the route may not Navigate 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’s changes in distance and direction are too complex, 50 waypoints may not mark your
path accurately. The receiver then assigns the 50 waypoints to the most significant points of your
track, and simplifies segments with fewer changes in direction.

The progress of satellite acquisition is shown in three stages:
• No signal strength bars— the receiver is looking for the satellites indicated.
• Light signal strength bars— the receiver has found the satellite(s) and is collecting data.
• Dark signal strength bars— the receiver has collected the necessary data and the satellite(s) are ready
for use.
As soon as the GPSMAP 176 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’, ‘2D Differential’, ‘3D’, or ‘3D Differential’ 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. 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 GPSMAP 176 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 GPSMAP 176. Initial reception of the WAAS signal may
take up to 15-20 minutes each day, 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 Differential’ 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 GPSMAP 176 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. The unit will not search for WAAS satellites if the unit is in the Battery Saver
mode.
From the Main Menu ‘Systm’ tab, highlight the WAAS field
and press ENTER to ‘Enable’ or ‘Disable’ WAAS.
To disable/enable WAAS capability:
1. From the ‘Systm’ tab, highlight the WAAS field, press ENTER and select either ‘Enabled’ or ‘Disabled’
and press ENTER.

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) to the right of 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:
When the GPSMAP 176 is using a differential correction signal
either WAAS or DGPS, a “D” is displayed in the signal strength
indicator bar for the satellites that are corrected.
• Searching the Sky— 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 GPS Location— at least three satellites with good geometry have been acquired and a 2 dimensional position fix (latitude and longitude) is being calculated. ‘2D Differential’ will appear when you
are receiving DGPS corrections in 2D mode and a ‘D’ will show on the strength bar of satellites
being corrected.
• 3D GPS Location— at least four satellites with good geometry have been acquired and your position
is now being calculated in latitude, longitude and altitude. ‘3D Differential’ will appear when you are
receiving DGPS corrections in 3D mode and a ‘D’ will show on the strength bar of satellites being corrected.
• Lost Satellite Reception— the receiver is no longer tracking enough satellites for a 2D or 3D fix.
• Receiver Not Usable— the receiver is unusable, possibly due to interference or abnormal satellite
conditions. Turn the unit off and back on to reset.
• Simulating GPS— the receiver is in simulator mode.
• GPS Off—the GPS receiver is turned off.

The Differential Receiver status will show one of the following:
• None— No optional beacon receiver is attached or enabled in the Comm tab (Main Menu) or WAAS
is turned Off
• Searching for WAAS— WAAS is enabled and the receiver is searching for WAAS signal
• Using WAAS— WAAS capability is enabled and the unit is receiving WAAS corrections
• Check Beacon Wiring— the DGPS setting is enabled in the Comm tab (Main Menu) but no DGPS
device is detected
• No Beacon Signal— DGPS receiver is attached, but not transmitting RTCM data to GPS
• Tuning Beacon— Receiver is tuning manual DGPS frequency
• Using Differential— Unit is receiving DGPS corrections
• Scanning for Beacon— DGPS receiver is scanning for available frequency
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
GPSMAP 176, the ‘DGPS Rcvr’ field will display ‘Off. The SNR will depend upon the mounting of your
DGPS receiver and the distance from the DGPS transmitting station.

Cleaning
The GPSMAP 176 is constructed of high quality materials and does not require user maintenance
other than cleaning. Clean the unit using a cloth dampened with a mild detergent solution and then
wipe dry. Avoid chemical cleaners and solvents that may damage plastic components.
,
Appendix A
Maintenance
WARNING: The GPSMAP 176 lens is coated with a special anti-reflective coating which is
very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING
AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the
lens using an eyeglass lens cleaner which is specified as safe for anti-reflective coatings
and a clean, lint-free cloth.
Storage
Storing alkaline batteries in the unit for long periods of time is not recommended. In order to
reduce the chance for battery leakage in the battery compartment and data card slot, remove the batteries when storing the unit for more than six months.
Do not store the GPSMAP 176 where prolonged exposure to temperature extremes may occur (such
as in the trunk of a car) as permanent damage may result. User information, such as waypoints, routes,
etc. will be retained in the unit’s memory without the need for external power. It is always a good
practice to back up important user data by manually recording it or downloading it to a PC (transferring
it to MapSource).
Water Immersion
The GPSMAP 176 is waterproof to IEC Standard 529 IPX7. It can withstand immersion in 1 meter
of water for 30 minutes. Prolonged submersion can cause damage to the unit. After submersion, be
certain to remove the batteries and data card and dry the compartments before reuse.
To resolve problems that cannot be remedied using this guide, contact GARMIN Customer Support
in the U.S.A. at 800-800-1020 or GARMIN Europe at 44-1794-519944.

LORAN TD System
Appendix G
LORAN TD Setup
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
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 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 GPSMAP 176 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 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.
66

6/18/2002, 10:01:15 AM
To set up Loran TD from the Main Menu:
1. Press the MENU key twice to display the Main Menu.
2. Using the ARROW KEYPAD, highlight the “Location Format” field on the ‘Units Tab” and press
ENTER.
3. Highlight ‘Loran TD’, press ENTER.
Appendix G
Loran TD Setup
4. Highlight the Setup Button located on the right side of the Position Format Field and press ENTER.
5. To change the settings of any of the five fields, highlight the field, press ENTER select/enter the
desired setting, then press ENTER.
6. When done, highlight the ‘Save’ button and press ENTER.
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 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.
You must know your GRI chain number, secondary stations to create a LORAN TD position. For
more information please read our LORAN TD Position Format Handbook, available at the GARMIN
web site, at www.garmin.com/support/userManual.html.
