Garmin GPS 12XL Owner's Manual (Software Version 2.00-3.62) - Page 28

REFERENCE TracBack WARNING: Setting the track recording to OFF will disable the TracBack function. Highlight 'TRACBACK?' and press ENTER to begin TracBack navigation. 24 TracBack Navigation GARMIN's patented TracBack feature allows you to quickly retrace your path using the track log automatically stored in the receiver. This feature eliminates the need to mark waypoints along the way and manually create and activate a route back to where you began your trip. Three track recording options are available: Off-no plot will be recorded. Fill-a track plot will be recorded until track memory is full. Wrap-a track plot will be continuously recorded, wrapping through the available memory (replacing the oldest data with new data). To select a track log option: 1. Highlight the 'RECORD' field, press E, select an option, and press E. Once a TracBack route is activated, it will lead you back to the oldest track log point stored in memory, so it's usually a good idea to clear the existing track log at the start of each trip. To clear the track log and define a starting point for a TracBack route: 1. From the Map Page, press E, highlight the 'TRACK SETUP' option, and press E. 2. Highlight 'CLEAR LOG?', press E, highlight 'Yes?', and press E. To activate a TracBack route: 1. Press G, highlight 'TRACBACK?', and press E. Once the TracBack function has been activated, the GPS 12XL will take the track log currently stored in memory and divide it into segments called legs. 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' symbol on the Map Page. 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 provided back to the starting point of your track log. Note: You may delete a TracBack waypoint from a route, but only if the route is not active.
