I recently purchased an RNS-E from ebay. Let me start off by saying I own a 2006 A4 (B7) with the Symphony II radio, no phone, no changer. I ordered the adapter through Deventer, Rum who came recommended through this site and very convenient since he's in Germany. I plug the adapter in and the brown oem plug doesn't fit into any of the connectors. Also, I hear the fuse from the cars main fuse box blow. So I go to replace the fuse and it blows again. I connect the attenna to the radio thinking maybe it needs to be grounded; still blowing fuses. I've written him back to see if he sent the wrong adapter but for now I have no idea what to do. I have searched and have researched and bookmarked pages and I just can't find an answer. Please help if you can.
