Hi all, thanks to this forum I have read up on, bought, fitted and coded an RNS-E into my A3. I have even managed to flash the firmware to include SDS and make the Aux active (the Black Edition comes with and Aux in socket). Massive thank you to all that helped - you know who you are!! Just need to bite the bullet and cut the mic cable and splice in the RNS-E to finish the installation (waiting for the bits from Audi). If anyone has any questions on this install let me know and I would be happy to try and help. I have to say the RNS-E transforms the interior of the car. It makes it look and feel much more premium. I think it sounds better too - but that may be my mind playing tricks on me! LOL I've only owned the car a fortnight and I've started modding it already. This doesn't bode well.
