Sitting at the lights minding my own business when the nav screen starts opening and closing repeatedly. A message on the screen reads "turning off monitor due to high temperature". Screen didn't feel that warm, been on for say 30 mins. So why is it opening and closing, looks like it's trying to fan itself to keep cool

. Is this anything you guys have seen or is it just F.U.B.A.R.
