So recently my reversing camera stopped working so thought it be the camera like I've had in the past with cheap £10 camera from amazon so ordered a new one swapped out now my head unit is just saying no signal when reverse is selected I thought oh I got a dodgy new camera so bought two new cameras each different makes and tried them still the same have replaced all the wiring from the rear light taps and still every time I put the van in reverse I get no signal I'm starting to loose my mind as my camera worked fine for two years prior this event with occasional camera swap out due to water ingress I also have just tried a power relay and still no luck and the headunit is new also.
Any help appreciated.
