21. FAQs
Why do I need the carrier’s data service?
The data plan allows you to access nationwide routes, maps, and Places content from the Telenav GPS Navigator
servers using the data communication features of your device. These services are different from your cellular airtime. To
order a data plan, please contact your wireless carrier.
How long after I apply for the data service until I can use my Telenav GPS Navigator system?
With data, you should be able to start using the Telenav GPS Navigator application right after it has been downloaded.
Why do I get the “GPS Location Settings” prompt when I first launch the application?
You need to turn on the Location settings so your GPS location can be detected, and for features such as navigation to
work within Telenav GPS Navigator. You will get a prompt message when you first launch the application with
instructions on where to change the Location settings. You must choose “Exit” and manually change the Location
settings.
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, the Speak It feature within the Telenav GPS Navigator application that allows you to make calls to
businesses does use voice minutes.
How do I increase or decrease the voice prompt volume and control the backlighting?
Speaker volume can be controlled with the volume buttons on the side of the device. The backlight can be controlled
from within Telenav GPS Navigator’s Menu >> Settings >> Navigation >> Backlight menu.
How do I conserve battery life on my device?
Set the backlight to “On at Turns” in Menu >> Settings >> Navigation >> Backlight menu. This option turns the
backlight on only when a turn is approaching.
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 are ideal conditions for GPS navigation?
Ideally, a device with a GPS receiver needs a clear view of the sky, starting from about five to ten degrees above the
horizon. Solid or massive obstructions can reduce accuracy or block GPS signals, and may cause extended initialization
time (time to first GPS fix). Common obstructions include tall buildings, covered parking lots, tunnels, trees, and terrain
features.
If you are parked in a covered parking lot or near a tall building, it is recommended that you move to an open area and
then begin to use Telenav GPS Navigator.
