As theres a thread bout headunits il ask about mine!!!
Have a Kenwood mask 7021se, firtsly there was a horrible crackling coming thro the speakers, if you increased the volume then it seemed to clear it!! Secondly the motor on the mask has packed up, werent a problem at first as you could coax it to turn/edject a cd, but now theres no motor noise at all!!
Im guessing its fucked but thought id ask if its repairable!!
Cheers
