To start a TracBack using the NAV key:
1. Press NAV, highlight TracBack, and press ENTER.
2. To stop TracBack navigation, press NAV, highlight Stop
Navigation, and press ENTER.
When a TracBack is active, the GPSMAP 392/398/492/498
takes the track log currently stored in memory and divides it
into segments called legs. Up to 300 temporary turns (BEGIN,
TURN 1, TURN 2, TURN 3,...., TURN X, END) are created
to mark the most significant 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 starting point.
• Set the Record Mode option on the track log setup page to
Fill or Wrap.
• The track log memory must contain at least two points to
create a TracBack route.
• If the track log interval is set to the Time option, the route
can not follow your exact path. For best performance, keep
the interval set to Resolution.
• 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 track log's changes in distance and direction are
too complex, 300 waypoints might not mark your path
accurately. The receiver then assigns the 300 waypoints
to the most significant points of your track, and simplifies
segments with fewer changes in direction.
For more information on setting up the Track options and saved
tracks, see page 57.
