You can reactivate google maps with a script that changes the URL being accessed, there is no technical reason for it not to work other than Audi choosing to disable it as it competes with the Here service they part-own. The reasons that Audi gave saying that the later higher resolution imagery is unsupported on the older technology is proven a total, utter lie.

Audi also turned off the MMI Online Destination query in October, this too was provided by google and folks are working on a script to change the URL.
You could say "Onine destination IKEA" and it would return a list of the nearest IKEAs - now it just says iinternet unreachable.
This is one reason to shun online smart technology in cars - little by little everything becomes unsupported and SSL certificates expire etc..
