Anyone out there found any differences in retrofitting a EU version RNS-E into a 2003 model A4 cabriolet WITH BOSE vs standard A4 installation. I've heard of some magic Bose pin, and also a difference in VAG coding. I'm guessing this has something to do with Audi automatically changing volume with top down/up/

Any ideas?

So far nobody has found a real difference between the 8E0 (A4 Sedan/Avant) and 8H0 (A4 Cabriolet) RNS-E. As long as the RNS-E is configured properly for your car it should work just fine.

The Bose pin is on all versions of the RNS-E and tells the RNS-E to disable the front speaker outputs (a Bose system is fully amplified) - not that magic really.
