I'm replacing the 15 year old aftermarket Panasonic Bluetooth/Back-up camera radio on my Suburban with the single DIN Boss BVCP9700A . Using existing wiring harness, running wires for new back-up camera and adding front camera(parking assist). Everything works until Reverse Input connected. Radio locks up on back-up camera and sets off relay under steering column. Have to factory reset radio and unplug relay(not sure what it goes to) in order to get radio to work again. Without Reverse input connected, back-up camera will not automatically come on when shifting into reverse. (Desired effect.)
