This is caused by a lack of power going to the device. The device should be plugged directly into the vehicle using the Rand McNally vehicle charger. If you are using a splitter, please remove it and plug the device directly into the vehicle. After re-connecting the device directly to the vehicle, press the reset button on the device. The device should power on and function normally.
If the screen does not display correctly after the reset, try another power source (a wall charger or another vehicle). You may need to press the reset button again.
If removing a splitter, resetting, and trying another power source do not resolve the problem, your device will require evaluation at our facility.
