6 Troubleshooting Questions
1. How do I charge my device? The WorldNav 3100 can be charged with an AC/DC adapter or the included
car power jack. AC/DC adapters can be purchased at the TeleType GPS website.
2. I can't get my device attached to the windshield. Place the suction cup firmly on the window and flip the
black switch which draws suction from the cup to attach the device. In cooler or drier conditions, you may
need to warm the windshield or moisten the suction cup for maximum seal.
3. When I touch the screen, the proper button doesn't light up. The screen may need to be
recalibrated. Please see the 'Calibration' section under 'Hardware Settings' for how to calibrate
your touch screen.
4. Does the USB cable charge the device? The USB cable is for connectivity. It cannot charge
the GPS.
5. I can't get power on my car adapter. If you can get power on the 110V cable but not in your car,
it is likely that the fuse inside the adapter is blown. Twist to unscrew the cover (the part that sticks
into the lighter) and replace the fuse with a fresh one.
6. My device is making a buzzing noise and is difficult to power up. How can I get the GPS to
turn on? This may occur if the 3100 battery dips below 15%. Follow this procedure to correct the
situation:
1.Remove SD card (by gently pressing the card into the device, it will then spring back out).
2.Connect the 12v power cord provided with the device while the motor is running in your car.
3.Press Reset (found on the back of the device).
4.Re-insert the SD card (make sure you hear a clicking sound that indicates the SD card was
inserted fully).
5.Press reset again. Let the device charge in the car.
Before removing the device from the car you may want to check the battery remaining indicator.
To check the battery life press the Menu button on the hardware that will bring you to the start up
screen. Press <Settings> and tap the <Battery> tab. This will display a bar that represents your
remaining battery life. If the bar appears to be continuously refilling, the battery is charging.
