Have just ordered a B8 A4 Avant with AMI and been told that I need to buy an additional cable for £30 to use it! It would seem that weather you spent 30k or 70k youve still gota buy one! Unbelievable! Can anyone tell me about the cable? Is it required to connect an ipod or just for usb drive?? Has anyone tried making there own based on the audi one yet? It must be a generic cable - Isnt it? There must be an aftermarket one about by now? s8craig Could this be a new venture?
