With regard to HUD... yes Audi have it, but the availability of features and options flows down both through a manufacturers range and also across the group - because VAG have a hierarchy, off which, VW is tier #2.
Yes, I was talking about a Mk7.5 AID with the km/h clock issue.
I've not heard of the AID going blank yet - it was my fear when it came along, given how the MIB can crash and burn...
The Mk8 might look a bit different in AID, but I doubt it will have anything amazing. The amazing in the Mk8 will be the other panel that replaces the switches... be amazed as you like about that... I'm not gripped personally.
