Hi, I got my CD changer today, which I bought from Ebay. The previous owner was a Conert + changer in it. But which he has expanded both. I have a chorus (according to Audi only installed from 2001) see picture. The stupid is only that the changer (parts No. 4B0 035 111A) is somehow not compatible with the radio. On the radio also does not radio the lighting when you turn on the light, but the display already. My TT EZ: 9/99 but model year 2000 controls that where I don’t like the new models from 2001 and therefore the lighting doesn’t work (I don’t think so). Was it really the opinion that every Audi changer is broadcasting with every Audi radio… do I now have the wrong changer or the wrong radio? Because if I connect it, nothing in the changer doesn’t even work out the compartment! Only when I’m playing from the radio of the red plug, where 2 cables are not occupied and I give the brown cable of it mass, does it play and al les, but there’s no Musi… can anyone help me out there????
