Garmin releases a new GPS receiver that is compatible with King mobile data system at approximately 1/2 of the original GPS35 price - NOTE: The GPS18pc comes with cigarette lighter power cord, unlike the GPS35pc you can't cut off the connector and wire into the vehicles power (this will damage the GPS receiver beyond repair) - this is because the voltage regulator is contained within the connector of the GPS18pc. You must get a female cigarette lighter connector or plug into the vehicle's cigarette/accessory connector. Garmin GPS18PC
