What is an ideal GPS environment?
A GPS receiver works optimally with a wide, clear view of the sky. Buildings, covered parking areas, tunnels and dense foliage can block the GPS satellite signals, disabling the receiver's ability to produce a location. If you are parked in a covered parking lot or near a tall building, you should move into a wide, open area before starting the TeleNav service. Similarly, you should place the GPS receiver in your car so that it has an unobstructed view of the sky. You may need to give the external GPS receiver 40 to 60 seconds to find its location if it has not been used for more than 4 hours.

How can I ensure my receiver will receive GPS signals?
Your GPS receiver should have an unobstructed view of the sky. The GPS signals are not affected by weather and will go through clouds, plastic and glass (with the exception of metal-coated, wire-mesh, and bulletproof glass).
Buildings, overhangs, tunnels, heavy foliage, and materials such as metal, concrete, and stone will block GPS signals.
In an automobile, it is best to place your GPS receiver on or near the dashboard so that it can receive GPS signals through the windshield.

How long will my battery last while TeleNav is running?
Running on a BlackBerry with no interruptions by voice calls, a fully charged standard battery will sustain TeleNav (with the backlight on) for about 150 minutes without a charging cable. Most mobile phones produce similar results.
If you use BlackBerry, you can gain additional time by choosing the power saver mode from Preferences, which dims the backlight except when audible instructions are being played.
The TeleNav Bluetooth GPS receiver will run more than 10 hours on a single charge. Bluetooth has a range about 10 meters. If you move your mobile device away from the GPS receiver more than 10 minutes, the Bluetooth GPS receiver will stop operating to save power.
