GPS accuracy can range from 20m to 100m, however most of the time the GPS is accurate to less
than 50 meters. Our external GPS receiver also uses WAAS technology to further reduce the error.
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 either be unable to locate itself (fix) or have extended
initialization time (start-up fix).
If you are parked in a covered parking lot or near a tall building, it is recommended that you move away
till you have a clear view of the sky and then begin to use the TeleNav service.
You may need to give the GPS a few minutes to find its location.
How do I know that the GPS has a signal?
The TeleNav application on your phone will alert you if the GPS does not have a valid signal. If this
happens, drive to an area where there is a clear view of the sky so the GPS can find itself.
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 the receiver’s 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.
How do I enter my destination?
Your destination can be entered in three ways. The first way is to call 877-886-9762 or 408-523-1429
and “dictate” your destination address to the Voice Address Input System. Then you launch the
TeleNav application on your Java phone and this address automatically shows up in the recent
destinations list.
The second way to enter your destination is to type it in using the keypad. Details are provided above.
The third way is to go to www.telenav.com , log in, and then enter your destination address, or multiple
destination addresses (up to 10 since this is all the phone can display at once).
Why do I have to call in a phone number to enter a destination?
Typing on a small keyboard can be tedious and so TeleNav provides you an easy way to enter the
address you’re going to. All you have to do is speak in your address and then TeleNav will guide you to
it.
What are Static directions?
When the GPS is not available, TeleNav will give you “Static Directions” that you can navigate through
by using the soft keys on your phone. Unlike GPS-based directions, with static directions you have to
provide the origin address yourself, and advance the instructions as you complete the driving steps by
pressing the right side of the Navigation key on your Nextel phone. You can also press the left side of
the Navigation key to see the previous step.
Also if you get lost you will have to exit and re-launch TeleNav to get new instructions from your current
location.
Why can’t I receive calls when using TeleNav?
