Garmin GPS II Owner's Manual page 49

To activate a TracBack route:
1. Press GOTO, and highlight 'TRACBACK?' (Fig. 43a).
2. Press ENTER.
Once the TracBack function has been activated, the GPS II will take the track log
currently stored in memory and divide it into segments called legs (Fig. 43b). 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 possible.
The active route page will appear, showing a route from your present position to
the oldest track log point in memory. Steering guidance to each waypoint will be pro-
vided back to the starting point of your track log (Fig. 43c).
