Does TeleNav use up my voice plan minutes?
TeleNav uses data to provide the navigation function. Using data does not use any of your voice minutes.
However, calling the Voice Address Input System does use about 75 seconds per address entered, and this
includes the Voice Call feature internal to the TeleNav application.
How accurate is the GPS?
GPS accuracy can range from 20m to 100m, however most of the time the GPS is accurate to less than 50 meters.
What is ideal GPS environment?
The GPS requires an open, clear view of the sky. Buildings, covered parking areas, tunnels and dense foliage can
cause the GPS to be unable to locate you or have an extended initialization time (time to first fix).
If you are parked in a covered parking lot or near a tall building, it is recommended that you move into an open area
and then begin to use the TeleNav service.
How do I know that the GPS has a signal?
The TeleNav application on your handheld will alert you if the GPS does not have a valid signal. If this happens,
move to an area where there is a clear view of the sky so that your device can hear the GPS signals from space.
Why does the GPS not work near buildings and other tall objects?
The GPS uses satellite signals from space to find out where it is. Therefore it needs a clear view of the sky. Tall
buildings and other objects that block your device from view to the sky make it infeasible to determine your location.
Sometimes the satellites are not overhead but near the horizon; in these cases the GPS must have a clear view of
the horizon.
