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.
Why does GPS not work near buildings and other tall objects?
Your device requires signals from GPS satellites in order to work, so it needs a clear view of the sky. Dense materials
(such as concrete, rock, steel, heavy wood), tall buildings, terrain features (like mountains, ridges, and cliffs), and large
trees can block or degrade GPS signals and may make it impossible to determine your location.
GPS satellites are not always immediately overhead and could be anywhere in the skies at any time, even low on the
horizon; however, there are enough satellites in orbit so that four or more will be view of your device if not blocked by
large objects, terrain, or dense materials.
How do I know that my device is receiving GPS signals?
TeleNav GPS Navigator alerts you if your device is not receiving GPS signals. If this happens, move to an area where
there is a clear view of the sky so your device can receive 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.
Will I be able to get a route when there is no GPS?
Smartly-cached map data on your handset allows you to navigate and get turn-by-turn re-routing directions even when
you have traveled a small distance outside the carrier’s coverage area.
How do I delete my list of “Recent Places?”
You may remove multiple addresses by logging into your TeleNav GPS Navigator account online at
.
In Recent Places, check the addresses you want to remove. You may also do this from your
handset by choosing Delete All in the Recent Places menu.
I have recently changed phone numbers. How do I move my subscription over to my new phone number?
Contact your carrier to change the phone number.
How do I reinstall the application on my device?
Contact your carrier to obtain the latest build for TeleNav GPS Navigator.
How often are your maps updated?
Our maps are updated quarterly.
I noticed there are stars next to some restaurants I have viewed or saved. How is popularity rated?
Popularity is calculated by the user-generated ratings, averaged by considering the scores of the ratings and the number
of users that have rated the location. A location accrues points based on how many stars it is given by TeleNav GPS
Navigator users. When a location consistently achieves above-average ratings, its popularity count increases. Negative
ratings lower the popularity count of the location.
