Ok, so I'm driving down the road using my navigation system and playing a cd fairly loud, but not THAT loud. All of a sudden the nav screen says "the monitor has been turned off due to high temperature" and then it open, closes, opens, closes, etc. and does not stop moving. It even continued for about 20 seconds after I pulled over and turned off the vehicle completely. I waited a minute and restarted... and all was back to normal. By the way, it was 40 degrees outside, so certainly there were no high temperatures. I thought maybe the screen kept opening and closing itself in an effort to fan itself for cooler air, haha! Seriously, has anyone seen this before or have any guesses what happened?
