i recently bought the blitsafe ipod interface for my B6 a4. it wokred great but my cable shorted out. i called the car stereo shop and they say i have to buy a whole new interface?!?! its a 4ft 8 pin DIN cable goes from the interface to the dock at the bottom of the ipod. my interface box is fine. does anyone know where i can find this cable and not pay another 80 bucks for a new interface. pls help. thanks
