Are you sure you need to reboot? I've had MCU freeze with AC full blast (in my case, always when switching around in my 12K+ USB song library). When it happens, I can wait a few seconds and it comes back on its own. I haven't tried to use the onboard manual with everyone reporting these issues, but even then, I found it to be more difficult that other methods.
To call this a safety hazard is a bit of stretch.
- One should never rely on just one method of verifying your surroundings: the camera should never be used as the sole method.
- If you knew you knew the backup camera was having an issue on that instance of backing up, only a fool would trust the camera AT ALL for the balance of that instance. You, as the operator of a 4,000+ vehicle, are ultimately responsible for what happens with it.
