Garmin GPS II - Manual (Page 51)

• If the receiver is turned off or you lose satellite coverage during your trip, the
TracBack route will simply draw a straight line between any point where coverage
was lost and where it resumed.
• If the changes in direction and distance of your track log are very complex, 30
waypoints may not be enough to accurately mark your exact path. The receiver will
then assign the 30 waypoints to the most significant points of your track, and sim-
plify segments with fewer changes in direction.
• If you want to save a TracBack route, copy route 0 to an open storage route before
activating another TracBack. Activating another TracBack or storage route will over-
write the existing TracBack route. (We’ll cover more on route management in the
following pages.)
• Whenever a TracBack route is activated, the receiver will automatically erase any
temporary waypoints (e.g., ‘T001’) that are not contained in routes 1-19. If there
are temporary waypoints stored in routes 1-19, the receiver will create any new
temporary waypoints using the first three-digit number available.
