i am having a problem my image is jumping in both dvd and back up camara my installer is sayng it the doms unit and the video signal is messed up anyone explerence similar problem its 05 rl.

 

I'm sure your installer checked but make sure he tried to wire both Video 1 and Video 2 to ensure they both DO NOT work. Also see if he used a different video cable just to ensure it was not his video cable that was the problem.
