If you have bought the car used from a VW dealer, you should insist that they supply the cables as they are an integral part of the "Approved Used" car. They often go missing and many used cars get sold without them. I kicked up a fuss when I picked up the GT, as there were no cables or mats. They were standard fit items with the car when it was new, so as an "Approved Used" car, it should be complete.
