Hi all I am new to the site so be gentle with me. I have a proble that I wonder if anyone has come across before or knows how to get around. I have the Audi Concert setup in my car with the iPod interface factory fitted but I have been unable to get it to work. When I connect the iPod it lights up, so it recognises a connection. But when I press CDC on the head unit, I just get the message 'NO CDC' flash up, so it is not recognising the iPod. I have tried a number of different iPods/iPhones but get the same conclusion. Does anybody have any suggestions as to what the problem might be?
