Problem Solution

My device is not acquiring

satellite signals

• Select Settings > System > GPS Simulator > Off.

• Make sure your device is out of parking garages and away from tall buildings

and trees.

• Remain stationary for several minutes.

The suction cup will not

stay on my windshield.

• Clean the suction cup and windshield with rubbing alcohol.

• Dry with a clean, dry cloth.

• Mount the suction cup (page 1).

The device does not

charge in my vehicle.

• Check the fuse in the vehicle power cable (page 22).

• Verify the vehicle is turned on and is supplying power to the power outlet.

• Your device can only charge between 32° and 113°F (between 0° and 45°C). If

the device is placed in direct sunlight or in a hot environment, it cannot charge.

My battery does not stay

charged for very long.

To maximize the time between charges, turn down the backlight (page 18).

My battery gauge does not

seem accurate.

Allow the unit to fully discharge, and fully charge it (without interrupting the charge

cycle).

How do I know my device

is in USB mass storage

mode?

When your device is in USB mass storage mode, a picture of a device connected

to a computer is shown on the device screen. Also, you should see one or two new

removable disk drives listed in My Computer.
