I was driving down the road going to work and as I was driving my Sync 3 screen I noticed it slowly kept getting darker and darker until it eventually turned all the way off and I couldn't get it to come back on. I would tap the screen and the beeps would make the beep noise but the screen was still black. When I got to my destination I turned off the car and opened the door so it would shut off everything and I turned the car back on and it seemed to work properly. Maybe this is a glitch with Sync 3?
