This guide will help you isolate the problem if the unit is at fault.

The vehicle's position is erroneous. Reset the unit and drive the vehicle in an area of good GPS reception to allow the unit to recalibrate itself. Move to a location where strong GPS reception is possible. No operation · Moisture condensation · Ambient temperature over 113°F (45°C) · Blown fuse ➔ Allow enough time for the condensation to evaporate (about 1 hour). ➔ Lower the temperature in the vehicle to below 113°F (45°C) by driving with the windows open or air conditioner on. ➔ Replace with a fuse of the prescribed rating (2A glass-type fuse located in the head of the cigarette lighter adapter). The unit is taking a long time to acquire GPS signal. It may take a long time for the unit to acquire GPS signal if it has been powered on in an area that is more than 200 miles from the area where it was last powered off.

Low RDS Traffic Signal (for Traffic Service Users) In order to improve the RDS Traffic signal strength, you may need to separate the RDS antenna away from the power cord on the Cradle. Carefully follow these instructions: 1 Power off the unit and unplug the Cigarette Lighter Charger. 2 Identify the RDS antenna. It is the thin, black, insulated wire that runs the fulllength of the thicker power cord. (See diagram on page 9) 3 Carefully cut the thin RDS antenna at the point where it enters the connector that attaches it to the Cigarette Lighter Charger. 4 Slowly peel the antenna away from the power cord to leave about 50 inches of the antenna separated and hanging free. 5 Place antenna on the vehicle dashboard or for best results, mount the antenna to the windshield using the provided suction cups (please see suction cup instructions for details) 36
