As you navigate with the receiver and pass individual track points, the legs will switch and countdown until you reach LEG 0 which is your final destination. The track points will be overwritten once the receiver records new position fixes. This activates BACKTRACK Route by saving the Track History as a 30 leg route and activating it. There may be some track points that are close to each other causing the receiver to skip 1 or more of these legs. 34 Magellan GPS 315/GPS 320 Auxiliary Functions Working with Sun/Moon and Fish/Hunt The Sun/Moon function displays solar and lunar calculations and the Fish/Hunt function displays times for excellent and good Fishing/Hunting.
