My screen is black and won't turn back on. I've tried rebooting by holding the scroll wheels and brake for 30 seconds. I've removed all USB devices.
I'm reading that it's possible to disconnect the 12V battery and the connector underneath the rear passenger seats, but all instructions say to turn off the car first. How can I do that if the screen won't turn on?
