TracBack Navifiation
Another method of navigating to a destination is by
using the TracBack function, TracBack allows you to
quickly and easily retrace your path using the track log
automatically stored in the receiver’s memor>t The advan­
tage of TracBack is to eliminate the need to mark way-
points along the way and manually create and activate a
route back to where you began your trip.
The TracBack route is created by reducing your cur­
rent track log into a route of up to 30 waypoints, and acti­
vating an inverted route along those points. Once activat­
ed, a TracBack route 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 your current trip
before you take off.
To clear the track log and define a starting point for a
TracBack route:
1. From the setup menu or map configuration page, high­
light the 'TRACK LOG' option. Press to access the
track log page.
2. Use the up arrow key to highlight the 'CLEAR TRACK
LOG?'option.
3. Press ^0. The clear log confirmation page will
appear. Use the left arrow key to highlight the 'Yes?'
prompt and press
To activate a TracBack route:
1. From the the setup menu or map configuration page,
highlight the 'TRACK LOG' option. Press CB to access
the track log page.
2. Highlight the 'TRACBACK?' option and press ^0.
Once TracBack has been activated, the unit will take
the track log currently stored in memory and divide it
into segments called degsT Up to 30 temporary way-
points (e.g., TOOT) will be created to mark the most sig­
nificant features of the track log in order to duplicate your
exact path as closely as possible. A TracBack route from
your present position to the oldest track log point will be
created as the active route (the active route page will
appear), and provide steering guidance to each waypoint
back to the starting point of your track log.
