We own a 2006 Monaco Diplomat that had an Aladdin System. We've had problems with our rear camera since we bought the Diplomat 2 years ago. Sometimes the camera works perfectly & other times it doesn't work at all, then other times it works intermittenly. The side cameras work fine. No one has been able to figure it out. I read somewhere that in some systems the wiring heats up & causes the problem, but we aren't good at that stuff so we just bear with it.

Full timing & loving it!
