TracBack NavigationAnother method of navigating to a destination is byusing the TracBack function. TracBack allows you toquickly and easily retrace your path using the track logautomatically stored in the receiver’s memory. The advan-tage of TracBack is to eliminate the need to mark way-points along the way and manually create and activate aroute back to where you began your trip.The TracBack route is created by reducing your cur-rent track log into a route of up to 30 waypoints, and acti-vating an inverted route along those points. Once activat-ed, a TracBack route will lead you back to the oldest tracklog point stored in memory, so it’s usually a good idea toclear the existing track log at the start of your current tripbefore you take off.To clear the track log and define a starting point for aTracBack route:1. From the map option page (see page 44), highlight the‘TRACK LOG’ option. Press E to access the tracksetup page.2. Use the up arrow key to highlight the ‘CLEAR LOG?’option.3. Press E.

Press E to access the track setup page.2. Highlight the ‘TRACBACK?’ option and press E.Once TracBack has been activated, the unit will takethe track log currently stored in memory and divide itinto segments called “legs”. Up to 30 temporary way-points (e.g., ‘T001’) will be created to mark the most sig-nificant features of the track log in order to duplicate youroriginal path as closely as possible. A TracBack route fromyour present position to the oldest track log point will becreated as the active route (the active route page willappear), and provide steering guidance to each waypointback to the starting point of your track log.To begin navigation of aTracBack route, highlightthe ‘TRACBACK?’ promptand press ENTER.To define the starting pointfor TracBack navigation,clear the track log at thebeginning of each trip.TracBackNavigationReference31
