Hey there compatrioate, what I can tell you is that if you have driver assistant plus like i do, the new model steering wheel won't work out of the box for cruise control and "wheel-auto-steering". I don't know if it can be made to work, looking into it now.
Next-prev track buttons will work out of the box.
Heated steering wheel retrofit doesn't work out of the box, but may be solvable with a control unit upgrade. I'll know in about a month.
If you want headache mode off, I'd advise that you stick with the old model that we both have in our idrive 6 cars.
