2010 Sedona EX. The rear view camera doesn't work - sometimes. When it works, shift to R, it beeps then video comes on and the green light is solid on. When it doesn't work it beeps and the green light blinks - no video. It does this often (except when I take it to the dealer). They tried hard to diagnose it during three oil change visits but it is hard to fix something when it works. Anyone else have this problem? Other than the camera, it is an excellent vehicle; nothing wrong with it. Not a heat problem (live in FL). It will happen when I drive out of the garage in the morning.
