Hello guys. I’m new here have already read a lot, but now I’ve re-enforced myself because I just don’t know any more First time to the vehicle it’s a Bmw E65 735i Bj 2004 So now to the problem. It all of a sudden started that the radio so said sound didn’t go any more, left the column for Fm,Am and Cd still stood there. I could also choose with the Idrive but he didn’t show any radio stations. First of all nothing thought about and started the journey home of about 150km. Dan to About 80km the radio is ‘jumped’ again. But soon it went out again, since the radio ‘dead’ So now this is 2 days and since yesterday loud noise from all loudspeakers. Partially the Idrive ‘dead’ it is possible to operate completely normal up to Navi, clock settings and just radio and it is constantly very loud. So now I went to the friendly today and it came out when error reading out the (Kcan line error) there were even more errors, so around the 20 but the Friendly everyone said they all came from this Kcan line error. Will definitely go to another branch because everything from de mechanic seemed a little funny to me. But well now I hope for solutions, tips and experiences am despairing because you can’t drive constantly with noises especially because that’s not exactly a benefit for the speakers. I thank you in advance already with your greetings from Fürth in Bavaria.
