  • 2004-2007 Touareg:  If your VW has factory navigation, this interface will not work with your digital amplified sound system.

Product Research


Radio Replacement Interface (for Volkswagen): The PAC RadioPRO 4 Radio Replacement Interface (RP4-VW11) allows the replacement of the original factory radio in select Volkswagen vehicles with an upgraded aftermarket head unit. It has been engineered to interface seamlessly with the automobile's computer data bus system, as well as retain important safety and convenience features; such as:

  • Factory amplified audio systems (including Dynaudio & Fender)
  • Steering wheel controls (SWC)
  • Rear seat entertainment (RSE)
  • Navigation based outputs (including vehicle speed sensor, reverse, & parking brake).
  • Retained accessory power (RAP)

Vehicle Compatibility: The RadioPRO 4 (RP4-VW11) is compatible with select 2002-2013 Volkswagen vehicles with factory LSFT-CAN databus radios. Compatible vehicles as of 3/12/2013 include:

Make Model Year
Beetle 2012-2013
CC 2009-2013
EOS 2006-2012
Golf 2002-2013
GTI 2006-2013
Jetta 2002-2013
Passat 2002-2013
Rabbit 2006-2011
Tiguan 2009-2013
Touareg 2005-2010
  • Premium Amplified Systems: 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. The RAP feature is not available in 2010+ vehicles equipped with a premium amplified system.
  • 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 digital audio amplified system seen when the vehicle is equipped with a factory navigation radio.

Radio Select Switch: The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle.

  • 2009+ CC, 2010+ EOS/Golf/GTI/Jetta/Passat/Rabbit, 2011+ Tiguan: These vehicles equipped with a Multi Function Display (MFD),  the screen must be set to audio mode for all buttons to program correctly. The OK & Back buttons can be programmed, but they will also control the MFD.
  • 2004-2010 Touareg: You can only program the Volume Up/Down buttons.

SWC Compatible: The interface comes pre-programmed for all of the vehicle's factory SWC functions and does not require programming, unless you wish to re-assign the SWC functions to different buttons. The SWC functions can be easily programmed; see control settings and functions below.  The interface retains programming even if your vehicle's battery is disconnected.

Note: The SWC harness contains a Blue/Yellow wire and a 3.5mm connector. You will only use one of the connectors, based on your type of aftermarket radio. The Blue/Yellow wire supports Kenwood, Newer JVC, OEM and Blaupunkt radios. The 3.5mm jack supports Alpine, Jensen, Older JVC, Clarion, Pioneer, Sony, Valor, and Dual radios. Not compatible with Soundstream head units.

  • 2009+ CC, 2010+ EOS/Golf/GTI/Jetta/Passat/Rabbit, 2011+ Tiguan: ..the audio screen will display the SWC functions as they are pressed on the steering wheel. It will also display "Programming Mode" whenever the programming  button on the side of the interface is pressed. The Blue/White remote input wire must be hooked up and the MFD must be in .audio mode for these features to be displayed.
  • 2006-2009 Golf/GTI/Jetta/Passat, 2007-2009 EOS/Rabbit: ..the up & down arrows on the SWC that also control  the MFD come programmed with functions but the SWC will control both the radio and the MFD. These buttons can be removed  by reprogramming the interface and not programming these buttons
Notes: In vehicles equipped with factory Bluetooth, the factory telematics module must be disconnected in order to use the Phone & Voice buttons. Not disconnecting the telematics module will result in the MFD switching to phone mode every time the Phone or Voice  buttons are pressed. The telematics module can usually be found under the passenger seat.

Customer Q&A

9 questions already asked

Radio won't turn on?
[ Angel  May 15, 2020 ]
3 answers
Thats a very vague question. I would first check your fuse. If that is ok i would then plug in the harness without the additional control box to see if the radio is working or not. If radio turns on then its the wiring on the control box. If it doesn't come on then it's the wiring on the harness. Most likely the wiring got mixed up somewhere during installation. Also if your fuse is blown then again, most likely a wiring issue
[ Jacob  May 16, 2020 ]
I had no issues with my PAC radio interface. I did have an issue with the other brand originally supplied (don't remember what ti was - it's been a while). It required a phone call to Crutchfield Customer Service. I received excellent telephone service from them and it was determined the original interface was not working properly and they sent me the PAC model which wired in and worked for me with no issues.Give them a call, it's worth the wait.
[ Charles  May 15, 2020 ]
sounds like something is wired incorrectly. Did you pay the extra for the pre-wiring?
[ Ed  May 15, 2020 ]
Will this allow me to retain the factory mic?

My 2009 VW EOS didn't have a factory mic I had to use the mic that came with the new radio and it works fine with my phone using Apple Car play
[ Ken  Oct 22, 2019 ]
How in the world do you install this thing? I have a Pioneer FH-X720BT.

For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.
[ Krissy  Oct 13, 2015 ]  Staff
Can anyone advise as to where the 2nd b/w wire "Remote On Input" should be wired to? The Pioneer AVH dash unit only has 1 blue/white wire for amp on.
[ Gerard  Jun 14, 2014 ]

Remote antenna
[ Juan  Sep 24, 2016 ]
I believe I had the same question about 18 months ago. I called Crutchfield support and the guy walked me through the wiring thing in about 15 seconds. Sorry, I don't recall the answer though.
