For those with MIB2 High / Technology Pack systems there is a replacement service via a new provider. The graphics are downloaded and stored on demand but you need an update and a valid Audi Connect Licence.
VAG Car Coding is able to perform the needed update, has been rolling this out for a while actually, via genuine firmware and authorised access to the VW Group online service tool to the following vehicles and related models such as S and RS cars:
Updates are ONLY for model year 2017 (MY17) and onwards vehicles ONLY.
A6 and A7 vehicles are not eligible. Currently awning further information re TT and R8 vehicles however we did have an R8 gen 2 v10 working with no issues the other day.
Those with MIB1 and MMI3G Plus or High / Technology Pack systems, Google Earth Overlay is no longer available and there is no replacement solution.
