Hi guys, I received a LED RNSE for my B7 A4 today and as the sticker on the unit is an Audi one I didn't need to switch any pins like on Seat units. Anyways obviously it unplugged and plugged in fine and after changing the language to English I had a wee play with and all seems to work ok. So I then tried to code it thru VCDS with my Genuine Ross Tech cable however clicking on the Navigation or the Radio buttons I just get a unit not found error. Any suggestions or help on this available? What am I doing wrong?
