*NOT* IN THE BOX (see 3rd photo)
- cable to take power from car stereo wiring to handsfree
- AUX-IN cable to take audio from handsfree to the car stereo wiring
- these cables are usually combined... this varies by car model
- to see examples search eBay for genuine vw quadlock
- ask VW or your cable supplier which cable(s) you require
- some VW stereos eg RCD 210/300/310/500/510, RNS 510 etc
only need a single, cheap, easy-fit, cable like item 403165046250
