When I bought the car it was all installed. When it turns on it says "front ok" then "rear n/a" The rear sensor is on (it goes on the rear plate) and looks to be wired. Does anyone know, does the rear sensor hook up to the box in the front of the car, or just straight to the warning device inside the car? Im thinking its ether not hooked up or not getting power.
question on built in passport radar???
