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 ....

Hi, I retrofitted a navi 4G0 035 193 E (7T2) in 2012 C7 / A6. (Removed 4G0 035 180 A)

Once installed the dealer removed CP lock and the nice is recognized. So; everything is fine so far.

Now I'd like to install (new) navi software (the official way) at the dealer but the system has blocked the process because the PR code (72) is not recognized in the (AUDI) car software database.

In other words: The software can not be uploaded in a retrofit system.

Any ideas how to solve this problem?

Should the PR code also be 7T2 and not 72?
