A while back we got a new Audi A1. At the time the dealer implied that because we had the all singing/dancing sound system, we only needed to buy an SD Card with the Maps on to enable the Sat-Nav option. As we had a TomTom, I had no desire to grease the dealer's sticky palms any further and I assumed that it would be simple enough to "acquire" a Map SD from somewhere else. The TomTom is rapidly becoming an expensive compass, so I've done a bit of digging into trying to get the Map SD and found some apparent flaws in my plan. a) Techno-Witch-Craft means that you can't just download the maps and copy/paste them onto any old SD Card - you need to buy a special one (£60 on fleabay) b) [Slightly contradictory] Due to Audi Techno-Witch-Craft the SD cards are linked to the VIN and therefore must be bought from a dealer (c£100-150) c) Despite having everything installed (according to the original dealer) and buying a SD Card, you then need to pay a dealer c£300 so that some spotty 19 year old can spend 30 second in your car with a laptop to switch on the satnav option. Can anyone confirm/deny my research? Any help or tips out there?
