Video is fairly good through direct inputs. A/V input requires the 4 contact connector; tip and 2nd segment are audio, third segment is ground and base is video. I seem to get a buzz when I connect video only, no matter installed or on batt. (Could be my source: Nikon Coolpix.) I have the parking brake indicator grounded and get the "distraction warning" when the car begins to move. Seems only to require the warning once per startup, perhaps again if you toggle the A/V input. Rear-View works as well but the "Mirror Image" disclaimer is annoying.
