Reason I ask is I'm trying to figure out what my 2007 S3 should have. I'm pretty sure my dash has been tampered with a bit, I have single din cage which is damaged, fitted with double din climate control unit! I also have a switch for DRL when the car has xenons! Could you even get this age of S3 with DRL? And to top it all off the single din stereo fitted didn't work, on further inspection it turns out that all the wires at the back are cut so now have no OEM plugs to attach stereo to! Please help, I have no idea what best solution is I just want a radio that works!!!!! Thanks in advance.
