Reference TracBack Navigation Default Track name Total Distance Change color of track line Check this box to display track Total number of points To activate a TracBack using the NAV key: 1. Press the NAV key, then highlight the `Follow Track' option and press ENTER. Highlight the track you wish to follow and press ENTER. Choose either `Original', which navigates you from the start to the end of your trip, or `Reverse', which navigates you from the end to the start of your trip and press ENTER. Once a TracBack has been activated, the GPSMAP 178/178C takes the track log currently stored in memory and divides it into segments called `legs'. Up to 50 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 point that you want to go back to (dock, etc. ). · 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. You must first save a track before using the `Follow Track' option. If there are no saved tracks, the message "There are no saved Tracks to follow" appears after you select `Follow Track. ' 55 Reference TracBack Navigation/ MOB: Man OverBoard · If the track log interval is set to the `Time' option, the route may not follow 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 your track log's changes in distance and direction are too complex, 50 waypoints may not mark your path accurately. The receiver then assigns the 50 waypoints to the most significant points of your track, and simplifies segments with fewer changes in direction. To stop TracBack navigation: 1. Press the NAV key, highlight `Stop Navigation' and press ENTER. For more information on setting up the Track options and saved tracks, see page 75.
