Why does the GPS not work near buildings and other tall objects?
The GPS uses signals from satellites so it needs a clear view of the sky. Tall buildings and other objects that block the
GPS receiver’s view to the sky may make it impossible to determine your location. Sometimes the satellites are not
overhead but near the horizon; in these cases, the GPS receiver in your phone must have a clear view of the horizon.
How do I know that the GPS has a signal?
The TeleNav GPS Navigator application on your phone alerts you if you do not have a valid GPS signal. If this happens,
move to an area where there is a clear view of the sky so the receiver can hear the GPS signals from space.
What happens if I’m using TeleNav GPS Navigator for driving directions and I lose the GPS signal while driving
across a bridge or through a tunnel or lose the GPS signal for some other reason?
TeleNav GPS Navigator remembers the speed at which you were driving before losing the GPS signal. TeleNav GPS
Navigator continues to give you driving directions based on an estimate of the projected distance that you may have
traveled at your last recorded rate of speed. TeleNav GPS Navigator recalculates your current position when you regain
a GPS signal and adjusts your driving directions accordingly.
