15. FAQs
Why do I need the carrier’s data service?
The data plan allows you to access nationwide routes, maps, and Directory content from the TeleNav GPS
Navigator servers using the data communication features of your phone. These services are different from your
cellular airtime. To order a data plan from TeleNav, please contact Customer Support.
Does TeleNav GPS Navigator use up my voice plan minutes?
TeleNav GPS Navigator uses data to provide its navigation functions. Using data does not use any of your voice
minutes. However, when you place a call to a business from within the TeleNav GPS Navigator application, your
voice minutes will be affected.
How do I increase or decrease the voice prompt volume and control the backlighting?
The backlight can be controlled from within TeleNav GPS Navigator’s Share & More >> Preferences >>
Navigation menu. Speaker volume can be controlled with the volume buttons on side of the device. If the speaker
volume is set to at least mid-range and you are still not receiving audio prompts, verify that your phone profile is
not set to vibrate or quiet.
How accurate is the GPS?
GPS accuracy can range from 20m (approx. 65 ft) to 100m (approx. 328 ft). Most of the time, the GPS is accurate
to less than 50 meters (approx. 164 ft).
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 receiver to be unable to locate a GPS satellite or may cause extended initialization time (time
to first GPS 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 GPS Navigator service.
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.
I noticed there are stars in the Detail screen of some restaurants I have viewed or saved. How is
popularity rated?
