TracBack Navigation (Follow Track)
The TracBack function allows you to retrace your path using the track log automatically stored in
the receiver’s memory, which eliminates 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 leads you back to the oldest stored track log point, so it’s
a good idea to clear the existing track log before you start your current trip.
To clear the track log and defi ne 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 highlight ‘Erase’ and press
ENTER
.
4. Highlight ‘OK’ and press
ENTER
.
You must fi rst save the track log before you can use the ‘Follow Track’ feature. The Save feature
allows you to store up to 15 track logs from certain times and dates.
To save a track log:
1. From the Main Menu, use the
ARROW KEYPAD
to highlight the ‘Track’ tab, then highlight the
‘Active’ tab to the right.
