I got my ML 500 in 2003, and everything has been working perfectly up until this past year.

My GPS navigation system screen is completely frozen. When I press the on button, it has a WAIT in the center of the screen. However the system is frozen, so waiting a whole day or even more won't even do.

I can't use my GPS, radio, cd player at all because it is frozen.

Is there a way that I can reset this? Or any way I can fix this?

Thanks
