GPS Origin Refinement
If you are using GPS navigation and you are in a parking lot or similar area where your location does not exactly
map to a specific street, you may see a page that shows TeleNav GPS Navigator’s best estimate of which street
you are on. This gives you the opportunity to change the starting street.
If you elect to change the starting street, a list of neighboring streets appears, and you can make an alternate
selection from the list. If you do nothing, the page disappears after a few seconds, and TeleNav GPS Navigator
uses the default street as the starting location.
If you are not sure which street you are on, simply start driving. TeleNav GPS Navigator detects your current
location and recalculates your driving directions as needed.
Audible Guidance Tones
The TeleNav GPS Navigator application delivers spoken audible directions. A preparatory audible tone is typically
heard no less than 30 seconds before reaching a turn, and an action audible tone is typically heard no less than 10
seconds before reaching a turn. The preparatory audible tone may not be sounded if the distance to the next turn
only allows time for the action tone.
The lead times for the audible guidance tones are increased proportionally to your driving speed. For example, this
allows more time for changing lanes before a turn if you are driving at highway speeds as opposed to driving more
slowly on local streets.
Miss a Turn?
Whenever you miss a turn, turn the wrong way, turn too early or too late, or otherwise get off the planned route to
your destination, TeleNav GPS Navigator automatically creates a new route to your desired destination and an
audible tone announces that a new set of instructions is available.
If you realize you have missed a turn or have otherwise gotten off the route, just keeping driving. TeleNav GPS
Navigator detects your current location and recalculates a new set of driving directions to get you back on track.
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 your carrier’s network, if you are off route and outside of the
carrier’s coverage area, you must return to your carrier’s coverage area in order for TeleNav GPS Navigator to
recalculate your route.
