For Golf, GTI, Rabbit, Jetta, GLI, EOS, and Passat 2004+ Plus cars with Multifunction Steering Wheel (Single Phone Button) Also works with Touareg with Volume buttons on Steering Wheel (Touaregs without a phone button can be used with just the volume button to answer and end a call) Installing this kit will allow you to use the “phone” and “volume” buttons on your steering wheel to control the functions of a Voice prompted Bluetooth module made for us by Parrot - the leader in bluetooth integration. It requires no splicing of wires and can be removed without a trace at any time. There are no wires to cut, splice or tap for factory-like bluetooth and with nothing to mount on the dash! The steering wheel phone button does all the work! Note: Tiguans require a different wiring harness. Please state in comment section if you have a Tiguan.
