Question 1:
2000ml 320: When loading cds th3 changer reads cd 1 then the message "changer error, please check changer" Is this a common problem that can be fixed or does the changer need to be replaced ? ( Bose system )

Question 2:
Will the wire harness brake light system for a hitch from a 1998 ml 320 fit on a 2000 ml 320 ?
