The navigation dvd player in the trunk is making a high pitched noise. It stay on even when everything is shut off. The nav and stereo are working ok. Has anyone else had this happen?

 

Is it a distracting noise? Can you hear it over the car engine noise? If so, might want to clean out the drive with some compressed air. Might be a small particle in there causing it to whine like that.

I have noticed that mine does still spin sometimes when the car is off, but it quickly turns off.
