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

Navigation, and press ENTER.

When a TracBack is active, the GPSMAP 182/182C takes the

track log currently stored in memory and divides it into segments

called legs. Up to 254 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.
• 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

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, 254 waypoints may not mark your path accurately.

The receiver then assigns the 254 waypoints to the most

significant points of your track, and simplifies segments with

fewer changes in direction.

tracks, see page 59.
