My backup camera stopped working for no obvious reason. This is yet another issue I've been having with the electronics since I picked the car up 2 months ago. The Sensus screen intermittently (3 times per week) goes out (completely black) until the system reboots after 2-3 minutes. I brought it to the dealer who couldn't find an issue. Not sure if the 2 issues are related but VERY frustrating. Any ideas?
