I've put it all in. Works very nicely. Found a button combination online that resets the flaps. The AC still needs doing so I won't use that until Monday when I'm getting someone with VCDS to do the reset for me. The fans seem to cycle on and off which I'm told means the compressor wants initialising or something.
VERY happy overall, RCD510 looks lovely and the DAB works well with a glass mounted aerial which is quite discrete. Did the pin swap and the ipod connection in the arm rest is working too
