Garmin 496 Manuale Proprietario

The TracBack function allows you to retrace your path using the 

track log automatically stored in the receiver’s memory, which 

eliminates the need to store waypoints along the way. TracBack 

routes are created by reducing your track log into a route with up to 

300 turns and activating an inverted route along those points. When 

activated, a TracBack route leads you back to the oldest stored track 

log point, so it is a good idea to clear the existing track log before 

you start your current trip. You must save an active track log before 

you can navigate it as a TracBack. 

1.  Press 

Direct To  , then highlight Navigate Track, and 

press 

ENTER.

2.  Highlight the track you want to navigate, and press 

ENTER.

3.  Use the 

ROCKER to select the point you want to navigate to 

(TracBack to), and press 

ENTER.

When a TracBack has been started, the GPSMAP 496 divides the 

track into segments called legs. Up to 300 temporary turns are 

created to mark the most significant features of the track in order to 

duplicate your exact path as closely as possible. To get the most out 

of the TracBack feature, remember these tips:

•  Always clear the track log at the point that you want to go 

back to (such as a dock or campsite).

•  The Record Mode option on the Active Track tab must be set 

to Fill or Wrap.

•  If the track log Interval option on the Active tab is set to 

the Time option, the route may not navigate 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 draws a straight line between any 

point where coverage was lost and where it resumed.

•  If the changes in distance and direction of your track are too 

complex, 300 waypoints may not mark your path accurately. 

The receiver then uses the most significant points of your 

track so there are fewer changes in direction.
