I have the double din on my 2004 Audi A3 TDI and looking at getting a new climate control unit and buttons to freshen it up due to the common worn and marked buttons. I was thinking of changing to the newer climate control unit (chrome switches) and the newer bank of switches located above climate control unit? (ESP, airbag light etc). Question is: Can either of these be just simply swapped over or is it not as simple as that? Am I right in thinking the bank of switches and bezel can be just swapped over to the never version but the climate control is a different size and shape and won't fit. Pic of current set up with signs of button wear etc and pic of wished set up.
