I've had my Mk 7.5 for a couple of weeks now and I have to say I'm loving the AID. There are a number of nice little touches that I keep discovering, like how the fuel gauge changes slightly when you hit the red to show you more detail about how much you have left, and how in Navigation view you get a graphical representation of how far you are through your journey - they left dial gets 4 blue quadrants that gradually decrease as your journey progresses.
That said, there is a bit of information duplication, and I wish it would show more verbose DAB info (such as song name) when in audio view - the head unit shows it, so I'm not sure why the AID can't!
