Hey guys! Just upgraded my CCC unit in my M3 but I think they are the same for 3 series. If not, someone let me know and I'll delete this. So I have the headunit, screen, controller, and center console trim (6MT) for sale. Nav sometimes will say "DVD Playback error" but was reading just may need an upgraded Nav disc. Didn't really investigate it much because I just upgraded the full system. Will sell as a whole or part out. DM me an offer!
