2011 Roadster. I fitted front and rear camera using the auxiliary input socket. It worked but cut out when the car moved. Nissan don’t like the facility to be used for DVDs so there is a circuit interrupter by the handbrake stoping the auxiliary circuit working when the handbrake is off. That’s easy, I’ve put a bypass in it, but it still cuts out when the car moves so the sneaky blighters must have put another cut out device somewhere. Any suggestions?
