It may take approximately 15 to 30 seconds for TeleNav GPS Navigator to update your route. If during this process
you make additional deviations from your current route, TeleNav GPS Navigator may have to contact its servers for
another new route.
Since TeleNav GPS Navigator requires access AT&T’s network, if you are off route and outside of the coverage
area, you must return to AT&T’s coverage area in order for TeleNav GPS Navigator to recalculate your route.
Navigation Views
The default navigation view is 3D moving maps, but you may wish to use another
option when you are navigating. Pull over and stop your vehicle in a safe place
before changing navigation options. You may even wish to plan your trip before
you start by looking at other navigation views.
You can access other navigation views after you start a navigation session, for
example from the Drive To menu. Press the VIEW softkey to call up the menu.
When you are viewing a Moving Map with audio features, press the TALK key to
repeat an audio prompt.
Use the Up and Down navigation keys in the View menu to select the desired
navigation view. Then press OK.
