In conjunction with a current JVC KD-xy USB / CD Receiver in a Golf III to this Adapter is totally unnecessary. JVC has its supplied cable designed to be the necessary cable, ie red and yellow cable, can change easily, as they are equipped with an appropriate connector. Even for me, as an absolute auto electronics layman who changing cables and installation was managed without difficulty. And without additional adapter does my JVC receiver exactly as I want.
The AIV 510614 Radiopezifischer Adapter - JVC I do not even have to unpack, so it goes back unopened.
