8.2 My Itinerary
Main Menu ->My Data ->My Itinerary
You can retrieve a planned itinerary by pressing Load Button . After having a loaded
itinerary (current itinerary), you can add, edit or save the itinerary. If a route already
exists before you retrieve an itinerary, a warning message will be shown.
8.3 My Trail
Main Menu ->My Data ->My Trail
You can show a trail on the map screen by pressing Show Button. Show/Hide is
toggled.
Trail settings allow you to record and name the travel tracks/routes you have taken to
your destination when you have a valid GPS fix for future reference. You can save
these and load (display) them at a later date. This is particular useful for off-road
situations where no route can be calculated to your destination. Only one trail can be
displayed at any time.
