Hi Cameron, trying to update my 2016 allroad - as I have MIB2 I should be able to get Android Auto and restore Google Earth with the K3663 Firmware... Just cant find anyone who has done it on an Aussie Model.
Cant find info much on international forums for our region and the fact we have limited to no Audi connect services here too.
With your maps Did you use the 20GB+ ROW version? the last lot I downloaded were around 5GB - likely AUS/NZ only.
