TracBack Navigation
The third method of navigating to a destination is by TracBack. TracBack
allows you to retrace your path by using the track log automatically stored in the
receiver’s memory, which will eliminate the need to store waypoints along the way.

waypoints and activating an inverted route along those points.
To clear the track log and define a starting point for a TracBack route:
1. Press the O key twice to display the main menu page.
2. Highlight the ‘Track’ option and press T .
3. Select the ‘Delete Track?’ option and press T .
4. Highlight the ‘Yes’ field and press T .
To turn on a TracBack route:
1. Press the G key, followed by the O key. Highlight the ‘Start TracBack?’ option and
press T .
