Thanks for the picture. I only have the AUX plug and not the USB beside it. The previous owner opted for the 6 CD changer instead of the combined AUX/USB (like in your picture).

Do you need a retrofit kit and can you not just plug in the USB port in the armrest glovebox and change the adaptor from AUX to AUX/USB port? I assume the plug connects right to the back of the head unit?

Thanks in advance.
