Hello, I have an A4 B7 Quatttro V6. I have removed the old Symphony II radio and put in an RNS-E unit, and used a wiring harness I bought from a company in Germany. The radio works but I think I have CANBUS problems because, no radio info is displayed on the instrument panel as it used to, and crucially, it does not power off when I remove the key. Is this because it needs coding? If so, who could I pay to do this for me. I live near Bath in SW England.
Thanks
Thanks
