Shame about your experience with DS Techs. I dealt with Mem, who helped me out a bit. Result on the 8500! Hope it works out for you after all this agro
After my experiences with Autoleads, I would not touch their wiring harnesses with a bargepole TBH. Connects2 are much better quality and seem to work better with Audi's weird audio systems.
Anyway, your's is a half-amped system. The non Bose systems might be Blaupunkt (open to be corrected here), which is what I had on my previous 2004 A4 S-Line (non-Bose). The Connects2 harness with the Active Plus box worked out really well on my current 8P S3. It allows you to adjust the signal per speaker/channel and really reduce the hissing and removes any popping sounds you sometimes get with Audi amped speakers and aftermarket HUs.
These keys should work for you - http://www.dynamicsounds.co.uk/auto...a3-a4-a6-a8-tt-radio-removal-keys-2-sets.html
As far as radio is concerned, if my memory serves me right, you might have a two aerial connections, one is a fakra and one is ISO. They look like this:
Fakra:
ISO:
So what you will probably need to do is have a dual fakra adapter with an extra converter cable to convert the car's male ISO/DIN connector to a fakra and plug both, fakra and converted ISO, into the dual fakra adapter, then the single ISO into the HU. (not sure if that makes sense, but the end result should look like this).
The second aerial adapter should look like this:
I've Googled ("Female Fakra To Female ISO") and found one on eBay.
Like you I had no end of problems with the aerial setup on the A4 and the 8L S3 before that. It seems that the strange combination of ISO and a fakra plugs on these cars is not addressed by any one adapter that I saw, which is a shame
