Hi guys, Currently an Audi A3 owner but my dad has just bought a late 2010 A6 2.0 TDI. As the title suggests I'm wondering how easy it would be to retrofit the DAB module and how I can check if the required windows are installed for the aerial. It has the HDD navigation system and both rear side windows look like they have the integrated aerials. I'm unaware which MMI version it is, most likely to be 3G. Let me know if anyone can help. Failing that we'll probably pay for a professional retrofit service, obviously this will be significantly more expensive though... :/ Cheers!
