Audi R8 USB port (replaces AUX port)
This USB port is to be used in conjunction with the Audi R8 stereo upgrade kit. It replaces the AUX port in the armrest and can be plugged into the USB port that is provided with you aftermarket stereo. This will enable you to plug your device into this port for charging and data transfer to the stereo, rather than having a loose cable.
Please check that you have an original AUX port present within the armrest. This can be installed if one isn't present, however, you will need to cut a hole for this to mount into.
