TracBack Navigation
The third method of navigating to a destination is
by using the GARMIN’S patented TracBack feature. The
TracBack function allows you to quickly and easily
retrace your path using the track log automatically
stored in the receiver’s memory. The advantage of the
TracBack feature is to eliminate the need to mark way-
points along the way and manually create and activate
a route back to where you began your trip.
The TracBack route is created by reducing your
current track log into a route of up to 30 waypoints,
and activating an inverted route along those points.
Once activated, a TracBack route will lead you back to
the oldest track log point stored in memory, so it’s usu-
ally a good idea to clear the existing track log at the
starting point of your current trip (e.g. your car or the
dock) before you get started.
To clear the track log and define a starting point
for a TracBack route:
1. From the Menu Page, highlight ‘TRACK LOG’.
2. Press
F
to access the track log page.
3. Use the
U
key to highlight the ‘CLEAR LOG?’ option.
4. Press
F
. A confirmation page will appear.
5. Use
L
to highlight the ‘Yes?’ prompt and press
F
.
To activate a TracBack route:
1. From the Menu Page, highlight ‘TRACK LOG’ option.
2. Press
F
to access the track log page.
3. Highlight the ‘TRACBACK?’ option and press
F
.
Once the TracBack function has been activated, the
GPS 120XL will take the track log currently stored in
memory and divide it into segments called legs. Up to
30 temporary waypoints (e.g., ‘T001’) will be created to
mark the most significant features of the track log in
order to duplicate your exact path as closely as possi-
ble. A TracBack route from your present position to the
oldest track log point will be created as the active route
(the active route page will appear), and provide steer-
ing guidance to each waypoint back to the starting
point of your track log.
