Hi! I found in archive this post http://e30-talk.com/topic/67919-aux-in-anschlussklinkenstecker-line-out-an-originalen-bmw-radios-nachr%C3%BCsten/?hl=%2Bumr%C3%BCstung+%2Beines+%2Bbusiness+%2Bcd+%2Bauf+%2Baux-in+%2Bzum+%2Banschluss+%2Beines+%2Bmp3players%3A&do=findComment&comment=872938 I have bavcaria c2 - and am trying to make propper line in. Soldered L+, R+ and - as in the pictures, but I have still one problem - there is a little mix mp3+radio. Is it because the - is soldered to the corpuss of radio - and it should be instead soldered to point "mass fur cassete" ? I don't understand german at all, so if You are answering could You please do it in english :) Maybe some of You have bavaria c2 for spares, mine is missing tone regulator button, and I have made a crack into display
