We have had this problem since day 1. The dealer will not address it, saying that the camera is aftermarket equipment and not factory installed. This is true, but we did purchase it as a factory option. It was installed by a local stereo shop. We went there - they were great. They ended up replacing everything over several visits, camera, controller, wiring harness, connectors, and they updated the software as well. I assume the dealership paid for all of this under warranty, as we were not charged. Nothing fixed the problem Its still there. Works OK about 80% of the time. The other 20% it takes several minutes to come to life. I assume its in the head end display unit in the van. Dealer won't help with it any further though.
