Thanks
i would buy a COMAND NTG4.5 unit and screen via ebay with the money you'll save on skipping the star diagnosis
there shouldn't be any recoding to the kombi instrument.
the unit itself should be plug & play but its possible you'll need a new screen since i don't know the screen type of an audio 20 unit in a facelift
