At the end of the day the official advice from Audi is:
-You need an active / valid Audi Connect subscription which is now chargeable. No sub = no service.
-You need a MY17 vehicle with Technology Pack with the exception of Audi A6, A7 and A8 vehicles which are excluded.
While the A6, 7 and 8 have the correct hardware my understanding is that Audi will not extend the satellite view licence for related VIN numbers.
In reality I have updated vehicles which Audi said were not possible, with Model Years earlier than listed, including non tech pack cars all via official procedures.
