My back-up camera and monitor were working great since picking up my new 2552 on Monday, but when we went out this AM it showed just a blue screen with “no signal” on it. I contacted Dave at PC and told him about the problem, he say he had never heard about it before and told me to have the local shop look at it when they fix the bathroom wall, under warranty. It will be interesting to find out what the local shop determines the problem to be. If I had the time I would be driving back to Elkhart to get these issues addressed.
