Tx for the recommend.
The standard MMI with virtual cockpit and wireless Apple Car Play gives me all the functionality I need - I generally use the Tom Tom app for big screen Nav - a step up from Waze with neat little features like automatically tracking and calculating you average velocity in speed average zones and a slightly less glitzy GUI than Waze.
The Google earth images are also available via the Google nav app on Apple Car Play - its the driver's display which has reverted to the pretty average map display that disappoints.
Booked in for 'upgrade' at next/second service at Audi CC.

Happy New Year all.
