I want to connect a Pure Highway to my 2008 RNS-E so I can get DAB in-car, plus play Spotify & have hands-free calling, but it needs an aux-in. I bought a cable off eBay and have connected it to the back of the unit and fed it through to the glove box but aux-in doesn't appear on the source menu. My local main Audi dealer didn't want to know, and a so-called specialist independent couldn't do it either. I've trawled around the web and have seen some code hack that you might be able to do if I can find someone local with VCDS, but I also saw somewhere that a software update will magically enable the aux-in. If I buy a later nav DVD, will that automatically update the software and will that give me my aux-in? If so, what year do I need and where's the best place to get hold of one? Any other suggestions? I'm in Cornwall, between Truro & St Austell Many thanks.
