17. 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 T-Mobile, please contact their customer support directly:
How long after I apply for the data service until I can use my TeleNav system?
Generally, it takes until the following business morning before the data services are fully provisioned. If you already have
data services, it should be no more than 4 hours before an added TeleNav plan is active.
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, calling the Voice Address Input System does use about 75 seconds per address entered. The Voice
Call feature internal to the TeleNav GPS Navigator application also uses voice minutes.
How do I increase or decrease the voice prompt volume and control the backlighting?
The backlight and speaker volume levels can be controlled from within TeleNav’s Tools & More >> Preferences >>
Navigation menu. Speaker volume can also be controlled with the volume buttons on the right-hand side of the phone. 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.
