The other day it was dark out and I started the B9. My display that shows all the audio / MPG info was blank as I was driving down the road. No lights at all as if the car was off (I have no NAV system just the DVD) I was at a loss for what was going on. I could hear the radio and was able to switch modes but no display. I hit one of the buttons (info I think) and it popped back on. I'm pretty sure I hit it before but maybe not. I did try the dim wheel and what not while it was off but nothing. It seemed to fix itself which makes me nervous. Anyone have this happen ever?
