what i thought i could do is take the voltage for the camera from the reverse lights then code it so when it goes into reverse the Tv switches to Av 1 and then the power comes from the reverse lights, or have it so that its live all the time so i can just switch to Av anytime and then see whats behind me even if im driving on a motor way ? do you think i would need anything else other than the camera the av cable and just wire it up ?
