So - lived with the car for just over a year and so far so good although I have noticed a few undocumented features in the MMI system
1: DAB Radio Station selection goes quiet - does not lose tune and if you tune away and back it comes straight on
2: Turn off car and open drivers door and MMI does not always shut down leaving screen up and radio playing
3: Reversing sensors (not camera version) when I reverse then drive away the parking sensor screen does not turn off despite going over the speed set to shut down parking assist.
Was wondering if anyone else has noticed these or other bugs regarding MMI.
