TracBack Navigation
4.  Next, the track will begin saving and then display the ‘Saved Track’ window when done. The default name, 
distance and number of points (1000 max) will be displayed. To change the name of the saved track, 
highlight the name fi eld and press ENTER/MARK, make your changes and press ENTER/MARK again. 
If you wish for the saved track to be displayed on the Map and Highway page, highlight the check box 
to the left of ‘Show on Map and Highway’ and press ENTER/MARK. Highlight ‘OK’ and ENTER/MARK 
press to save the track.
To activate a TracBack using the NAV key:
1.  Press the NAV key, then highlight the ‘Follow Track’ option and press ENTER/MARK.
2.  Highlight the track you wish to follow and press ENTER/MARK.
3.  If you wish to navigate from the end to the beginning (reverse) of your trip, press the ‘Invert’ SOFT KEY.
Once a TracBack has been activated, the GPSMAP 2006/2010 will take the track log currently stored in 
memory and divide it into segments called ‘legs’. Up to 50 temporary ‘turns’ will be created to mark the 
most signifi cant features of the track log in order to duplicate your exact path as closely as possible. To get 
the most out of the TracBack feature, remember the following tips:
    •  Always clear the track log at the beginning of your trip.
    •  The ‘Record Mode’ option on the track log setup page must be set to ‘Fill’ or ‘Wrap’.
    •  There must be at least two track log points stored in memory to create a TracBack route.
    •  If the track log interval is set to the ‘Time’ option, the route may not follow your exact path (keep 
  the interval set to ‘resolution’ for best performance).
    •  If the receiver is turned off or satellite coverage is lost during your trip, the TracBack will draw a 
  straight line between any point where coverage was lost and where it resumed.
    •  If your track log’s changes in distance and direction are too complex, 50 points may not mark 
  your path accurately. The receiver then assigns the 50 points to the most signifi cant points of 
  your track, and simplifi es segments with fewer changes in direction.
To stop TracBack navigation:
1.  Press the NAV key, highlight ‘Stop Navigation’ and press ENTER/MARK.
