When I was parking at work today, the reversing camera showed naught but for the white lines predicting my car's path. I gave it a few seconds, but it never came 'online', as it were. I am still capable of using the old Mark I Eyeball fortunately, and was able to park without further incident, but is this a common problem? When I head out to lunch today, if it's still happening, I'll try a soft reboot, but if that doesn't bring my camera back is there anything further I can do rather than add an item to my already-scheduled service appointment next week for an unrelated issue?
