Hey folks, I jut swapped my S3 (8P) with RNS-E and Bose, for an A4 (B7) with RNS-E and non-Bose. I connect my iPod through a Dension GW100 and this seems to just be a straight swap between the cars. Dension quote the same part-no in their compatibility lists, but, I'm sure something isn't quite right, the sound seems like it's missing all the mid-range and the bass is lacking punch. Is this normal for what I've got? Am I likely to need to get a different harness? If I was going to upgrade to improve the situation, what way would be best? The seller advertised the car as having a Harmon Kardon system, but all I could find was a "Harmon" sticker on the amp I found in the boot. Can anyone shed any light on what this is all about?? Thanks all!
