$249.00 RP4-VW11

All-in-one radio replacement and SWC interface

  • 2002-2005 Vehicles: In these year vehicles the RP4-VW11 does not provide a Reverse output trigger. This signal is unavailable on the data bus. You must be replacing a factory Double-DIN radio. If the vehicle came equipped with a Single-DIN radio, the RP4-VW11 is not compatible.
  • 2004-2007 Touareg: Does not retain amplified system when the vehicles is equipped with factory navigation radio
  • In Premium Amplified Systems only two input channels can be used from the aftermarket radio, therefore there will be no fading capability of the aftermarket stereo.
