wow! ..I am retrofitting the 7T2 ...as I thought maps would be the same .... to retrofit 7T2 is much easier than the 7T6 MMI 3G ...for which I have to change Screen , touch pad , main unit 5F , cable back to the screen and maybe more thing ...is more $ expensive and more complicated I think ?? - so I bought a Delphi Radio 7T2 ...and still waiting to check if any chance to get the maps somewhere and somehow ... in the future I think Audi´s suppliers , like Delphi must release some cartography for their unit and the aftermarket sales ...? maybe ....
