To activate a TracBack route:
1. Press GOTO, highlight ‘TRACBACK?’ (Fig. 43a), and 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 will be created to mark the most significant features of
the track log in order to duplicate your exact path as closely as possible. These
points will be indicated by a ‘T001’ number on the waypoint list, and by a “T” sym-
bol on the Map Page (Fig. 43c).
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. Note: You may delete a TrackBack
waypoint from a route, but only if the route is not active.
