Navigating A Saved Track; Tracback Tips - Garmin GPSMAP 276C Owner's Manual

Navigating a Saved Track

You can save your track log to use later as a TracBack, which
reduces your track log into a route with up to 300 turns. When
initiated, a TracBack route leads you back to the oldest stored track
log point. It is a good idea to clear the existing track log before you
start your current trip. Also, you must save an active track log before
you can navigate it as a TracBack.
To start a TracBack using the NAV key:
1. Press NAV, highlight Navigate Track, and press ENTER.
2. Highlight the track you want to navigate, and press ENTER.
Selecting a saved track.
3. Select the point you want to navigate (TracBack) to, and
press ENTER.

TracBack Tips

When a TracBack is initiated, the GPSMAP 276C 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 which you want to
go back (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 might 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, 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 might not mark your path accurately.
The receiver then uses the most significant points of your
track so there are fewer changes in direction.
