I'm getting frequent problems in my MY04's CD player, where the CD will suddenly stop playing, and the unit will flash DISC in the display. According to the manual, this indicates that the unit is unable to focus, likely culprit being a dirty or damaged CD. My CD is of course perfectly clean and without scratches... I'm guessing that I need to clean the lens.

Has anyone had experience cleaning the CD lens in their car stereo? Do the typical CD lens cleaner kits work?
