Initializing the GPS Receiver
The GPSMAP 176/176C must be initialized before it can be used
for navigation. 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 176/176C 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. If
the unit has not been used for several months or has moved over six
hundred miles between uses, the Almanac can become “cold.” If the
Almanac is “cold,” the orbital data is no longer valid and your unit
may take longer to lock on to satellites while updating the Almanac.

TracBack Navigation (Navigating a Track)
TracBack allows you to retrace your path using the track log
automatically stored in the receiver’s memory. This eliminates the
need to store waypoints along the way. TracBack routes are created
by reducing your track log to a route of up to 50 turns and activating
an inverted route along those points. Once activated, a TracBack route
leads you back to the oldest stored track log point, so it is a good idea
to clear the existing track log before you of your current trip. Refer to
the “Track Tab” on page 55 for more information.

If there are no saved tracks, the Navigate Track option is disabled.
Once a TracBack has been activated, the GPSMAP 176/176C takes
the track currently stored in memory and divides it into segments
called “legs.” Up to 50 temporary “turns” are created to mark the
most significant features of the track in order to duplicate your path as
closely as possible.
28 GPSMAP 176/176C Owner’s Manual
B OASIC PERATION > G OING TO A ESTINATION D
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 return
to, such as the camp site or dock.
• Set the Record Mode Fill option on the track log setup page to
or .Wrap
• At least two track log points must be stored in memory to
create a TracBack route.
• If the track log interval is set to Time, 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, TracBack draws 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.
To stop TracBack navigation, press NAV. Highlight Stop Navigation
and press . For more information on setting up the Track ENTER
options and saving tracks, see pages 55-56.

Compass Page
Whenever a Go To Navigate Track Navigate Route, (TracBack), or
is activated, the Compass page guides you to your destination with
digital readouts and a graphic compass display, which includes a
bearing pointer. Use this page when travelling at slower speeds,
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 are 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.
The bearing pointer and compass ring may point in NOTE:
various directions when you are stationary or at very low speeds.
Once you start moving, the pointer is correct.
Compass Page Options
The Compass page features a menu page that provides access to
layout and data field options. The data window, located at the top
of the page, provides a user-selectable layout of various types of
useful data. Each data field can be configured to display several data
options. The data window layout can also be changed to display
more/less data fields and change the actual size of the data displayed.

provides digital and graphic steering guidance to the destination. The
right side of the Highway page features user-selectable data fields that
display useful navigation information. A compass ribbon is displayed
at the top of the page to show your current heading along with a dark,
vertical bar which indicates the bearing to your course. To stay on
course, steer towards the dark, vertical indicator (or arrows) until it
lines up with the lighter gray bar in the middle. The bottom section
of the screen provides visual guidance to the waypoint on a graphic
highway display. The line down the center of the highway represents
your heading.
As you head toward your destination, the highway perspective moves
to indicate your progress to the waypoint and which direction you
should steer to stay on course. If you are navigating a route, the
Highway page shows each route waypoint in sequence connected
by a black road with a white line down the middle, which is your
desired track line. Nearby waypoints not in the active route can also

M M > AIN ENU GPS TAB
GPS Tab
The GPS tab provides a visual reference of satellite acquisition,
receiver status, and position accuracy. The status information shows
what the receiver is doing at any given moment. The sky view and
signal strength bars give 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. As the receiver locks onto satellites, a signal strength
bar appears for each satellite in view, with the appropriate satellite
number underneath each bar.
The progress of satellite acquisition is shown in three stages:
• No signal strength bars—the receiver is looking for the
satellites indicated.
• 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 176/176C has collected the necessary data
from the best satellites in view to calculate a x, the status eld
indicates 2D or 3D status. The unit then updates the position, date,
and time.
You can use the sky view to help determine whether any satellites
are being blocked, and whether you have a current position x
(indicated by a , , , or 2D 2D Differential 3D 3D Differential in the
status eld). 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 conguration, causing the top of
the sky view to align along your current track heading.
WAAS Capability
The GPSMAP 176/176C 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 benet 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 Pacic Ocean,
in a geostationary 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.
