Hi, can anyone tell me if the RNS-E MK2 will retro fit a 2006 A4 3.0 tdi S line Quattro Cab? I have what I guess to be the MK1 fitted (OEM) with the 2012 map disc at present & the phone (bluetooth) voice dialing works really well from the steering wheel button & I don't want to compromise this function. There's a ebay seller who has a couple of MK2's for sale & he says it will retro fit ok as a few people have bought these & changed from MK1 to MK2. but he's a little unsure about the voice dialling function. I asked at my local dealer they said that they didn't think the MK2 would be compatible with my car but suggested I asked the question here. I've tried searching but I can't seem to find an answer. I like the fact that the MK2 will take 32GB sd cards & have a better screen etc. I just need to be sure before committing £500 plus & finding out it won't work.
