PAC's RP4-VW11 wiring interface lets you replace the factory radio in select 2002-up Volkswagen vehicles. You'll retain your factory steering wheel audio controls, the full entertainment system, and the use of your factory amplifier, if present. The interface supplies all navigation outputs and accessory power. Warranty: 1 year.

Installation Notes: 

  • 2002-2005 Vehicles: This interface only works when the factory radio is a double-DIN (4" tall) radio, and does not provide a reverse output trigger.
  • 2004-2007 Touareg:  If your VW has factory navigation, this interface will not work with your digital amplified sound system.

I haven't installed a stereo in over 25 years - I don't think they made stuff like this back then. Not having to deal with a soldering iron or shrink-wrap made this a 20 minute install start to finish with no rework.

Pros: Dead simple to install

Does It's Job

Ed from Westchester, NY on 10/15/2018

2006 Volkswagen GTI

Verified customer (What's this?)
Verified employee purchase (What's this?)

It's a steering wheel control (SWC) that works fine for my 2006 VW GTI MKV. The one I received was one firmware update behind the latest version. Unfortunately, firmware updates require the purchase of an additional $40-$50 dongle and connection to a Windows PC to apply the update.

Pros: Integrates steering wheel controls on my 2006 VW GTI MKV. Default SWC values for radio brand selected work well. Can utilize short and long presses for each button to control two functions. Periodic firmware updates available.

Cons: Firmware updates require purchase of another $40-$50 dongle and connection to a Windoze PC.

PAC RP4-VW11

Crutchfield customer from Plymouth Mtng, PA on 12/17/2017

2007 Volkswagen Passat

Verified customer (What's this?)
Verified employee purchase (What's this?)

Adapter works OK and basic connections for power and ground all work as they should. My only disappointment is that in my application (a Red screen 2007 Passat), only the steering wheel controls for volume work properly. Although the track up/down arrows do control the head unit, they also control the screen in the cluster at the same time (scrolling through your mpgs etc when you don't want to, or changing the track when you want to check your mpgs). You can un-program it, but that means you still spent more money just to be able to control volume only. Although the description of the product does tell you this, it is somewhat hidden in the details page among a lot of other information. It would have been nice to have it tell me this limitation on the screen where it asks if you want the basic or the upgraded interface. The information is in the details screen, and I entered my car info, so the ordering system should be able to combine the two and give buyers these details more obviously before they purchase and are surprised and disappointed after the fact.

PAC RP4-VW11 Wiring Interface

BryanG from Texas on 1/18/2016

2011 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

I've only had this hooked up a few days but so far it's working well enough. There wasn't a ton of information in the manual, but I was able to follow a few different online videos on installation to get it done in a reasonable amount of time. My SWC maybe don't operate correctly 100% of the time but it's still effective (I may hit volume up 5x and it goes up 3 type thing). Another review on a 2011 Jetta explained that the phone button in the steering wheel won't work but he also talks about how the PAC can be reprogrammed to work with your buttons. I have no idea how that works. Maybe ask that guy.

Pros: Steering Wheel Controls mostly work. Installation is reasonable.

Cons: I believe it's made for multiple vehicle manufacturers so it's not 100% perfect on the VW Jetta.

Middle of the road

ArwinR from Indiana on 1/18/2016

2008 Volkswagen R32

Verified customer (What's this?)
Verified employee purchase (What's this?)

So far this unit did what I needed. The steering wheel volume and phone buttons work fine. Although I was able to complete the installation on the first try with no errors, the instructions left much to be desired. The "schematic" in the instructions was useless. The instruction sheet says the Retained Accessory Power would work, but it doesn't. I contacted the company and they said this was a cut and paste error in the instructions. My car doesn't have an accessory position for the ignition. If I ever need to do a firmware update on the head unit, I'll have to do it with the car running. According to Kenwood a firmware update can take 30 minutes. In that time the headlights might drain the battery since they would be on with the ignition switch in the on position. From time to time the volume at the head unit is louder than where I left it when I start the car. Maybe it is a problem with the head unit, but I doubt it. If these limitations aren't a concern to you then this accessory would be worth buying. For me I think MAYBE it wasn't worth it.

Pros: The volume and phone buttons work.

Cons: Poor installation instructions No Retained Accessory Power despite claim in the instruction sheet Possible bogus volume setting when the car is started

Confusing Instructions

More Details Needed from South Carolina on 2/16/2015

2007 Volkswagen GTI

Verified customer (What's this?)
Verified employee purchase (What's this?)

Requiring this option to retain controls from a factory perspective should include details as to what each connection is for. The instructions sent are basic gives you high level descirptions but detail oriented people such as myself would have a much easier time following the instructions if more details were included.

Pros: Retains factory functions

Cons: No detailed instructions, what is sent may make sense to someone who installs these daily but for the one time installer, mass confusion for connecting to a different harness and in vehicle.

Terrible quality control

Liam from California on 12/9/2014

2004 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

I would give .0000001 Stars. two of these were shipped to me and both were bad before I ever got them. There seems to be a lack of quality control. It has taken more than a month and the stereo I bought is still not in and working due to the failure of this simple part. After being assured repeatedly that I needed this item, the tech after several phone calls tells me there is a much less expensive and better suited modle for my car. I never needed steering controls because my car does not have them. What a waste of time.!

Pros: DOn't know any , never got a working model.

Cons: No Quality control . The tech admitted they do not test them before sending them out. They really may not be necessary for your car, it seems like a scam to get more of your money. I doubt they will ever print this review.

Crutchfield response on 12/9/2014
We always encourage customers to call us before ordering to make sure they're getting the best options for their needs. If you don't need the steering wheel control adapter, then yes, there's a much less expensive option for installing a stereo in this car. We're glad that the other adapter finally got the job done.

Great Fit...However, an easy fix for VW should be included

Ches from Phoenix, AZ on 11/25/2014

2004 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

Excellent product. Wire to wire hookup is a breeze. However, you have to attach the power antenna wire even if you do not have a power antenna in your VW. This will serve as your AM antenna. I did not know that so I had it all done and I switched it over to AM to listen to a game. Just static. I called customer service. To Crutchfield's credit, they answered the phone immediately and answered it clearly and I was able to correct the mistake. But what gets me is that the customer service rep says he gets this call all of the time. Well, if numberous customers make this mistake (and it is an easy one to make, I don't have a power antenna so I do not connect those wires), include something in the directions. You know the make, model, and year of the vehicle. When the order is placed and the directions are printed, at a page for the VW power antenna being the AM radio booster. One sentence...happier customers.

Pros: color coding makes it easy

Cons: Power antenna means AM radio booster in VW.

Perfect Fit...but

colnago888 from White Rock, BC on 11/11/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

This was a recommended harness which is supposed to work perfectly with your existing VW MKV electronics including the steering wheel controls (SWC). Minimalist in design and fairly easy to use. The module which has switches depending on the make/model of the stereo works with just about every model out there. First impression with my first install is good as I have not re-programmed any of my SWC. There are instructions with the RP4, but it is for experienced installers and not the average DIY person. Again, Crutchfield Tech Support is there to help out if you need them. Not sure how this compares with the others (ENFIG, etc).

Pros: Simple and minimalist in design. Instruction manual is nice and concise, not too overwhelming. Make sure you use the Crutchfield Tech Support before putting the unit back in, or you may need to remove the stereo and face plate if you need to reprogram (like I did).

Cons: Instruction manual not for the faint of heart. Splicing instructions are fine, but re-programming is a nightmare, at least for me. Call Crutchfield Tech support and enjoy the rest of your day.

Wow!!!! This was the best interface I could ever had bought. Before looking in to this I was told that if I wanted a new head unit I would have to swap out my stock amp and speakers. Well this gem will allow you to keep everything and if you have radio controls then you can keep those too!

Pros: Awesome! It just works and was easy to install.

Cons: Took me some time to. Figure out how to. Connect the power to the antenna as the same wire its also used as the amp remote. After doing some research and reviewing my installation I had to splice and connect the wires three way. I expected better instructions.

Verified employee purchase (What's this?)

I am new to car audio wiring and was able to successfully connect the PAC RP4-VW11 to my Alpine radio harness. There are wires marked for Navigation in a taped bundle that had to be used to make my radio work with my 2010 VW Jetta. If you are not sure which wires, I suggest contacting Crutchfield support like I did and they walked me right through my wiring questions. I contacted support late into the evening - 11PM and got all the help I needed. I recommend this product and Crutchfield.

Pros: Easy to work with Intuitive connections

Cons: Instructions that came with the PAC are not very detailed, but worked fine

Works great for VW w/ Monsoon, but NOT plug n play!

darren from redwood city, ca on 10/12/2014

2003 Volkswagen Passat

Verified customer (What's this?)
Verified employee purchase (What's this?)

I either spent too much time or not enough reading the VW forums on replacing my Monsoon head unit. I got this with my new Sony head unit thinking it would all plugin together and allow me to use the existing factory harness. Which is does - kind of - but you still have to strip, solder, and heat shrink tube wires to install a new head unit. 4 stars for allowing me to retain accessory power and not have to rip out old factory amp, etc. Minus 1 star for wishing there had been better product description. I would buy it again.

Pros: Allows you to replace VW factory head unit without too much hassle

Cons: You still have to solder (or crimp) wires and tape/heat shrink them to install it.

PAC RP4-VW11 Wiring Interface

Crutchfield customer from Albany, NY on 8/29/2014

2003 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

The wiring interface is critical to installing an aftermarket radio in a VW. The interface eventually worked like a charm, but I had significant difficulties getting the wires to properly set within the harness itself. The unit would sometimes turn on, and sometimes would not power on. After many aggravating attempts to fix the problem (along with many calls to Crutchfield- who were great), I gave up and took it to a local shop. They had to re-seat some of the wires within the harness, and then the unit worked great again. So the sum of it is- the interface works great if it works. If it doesnt, it leads to endless aggravation and a waste of time (and money, if you give up like I did).

2006 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

Paired this with a Kenwood receiver in my daughter's Jetta. Install was easy and it works great. It has the ability to program some features in order to assign 2 functions to each button of the steering wheel controls (short touch and touch and hotd). Also, on her particular vehicle with a multi function display (MFD) there is a slight issue in that cycling between the pages of the MFD also skips tracks (iPhone, Pandora) or preset stations (FM, AM, SAT). This can be avoided by removing the program function for the steering buttons to change the track, or preset.

Pros: Easy install, good value.

Cons: None so far

Excellent Adapter

alphaseinor from Denton, TX on 7/17/2014

2002 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

I purchased this because I needed to keep the existing Monsoon amplifier, and wanted to keep the controls on the steering wheel. Everything worked, except in a 2001 Jetta I needed to provide switched power to the radio. It's unfortunate they figured out all of the CAN bus stuff for the steering wheel, but not the VW specific key power issue. Not difficult to rectify, so still gets 4 stars, I just ran a fused connection to the radio bypassing the harness connector.

Pros: Relatively simple installation Steering wheel controls were maintained Factory Amplifer turns off when instructed

Cons: No switched power built into the adapter.

anon from Vancouver, BC on 6/20/2014

2005 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

2005 VW Jetta: I didn't realize it when I bought it but this adapter isn't just for the steering wheel controls. It also provides the wiring to connect your head unit's speaker and power wires to the factory harness. In other words, I didn't have to do any soldering or crimping in the car. I just soldered the new head unit's wires to the PAC adapter's wires in the comfort of my work bench. Installing the head unit in the car was literally plug n play. The VW Jetta doesn't have an accessory or switched power wire so it was great that PAC's adapter provided one. It's only rated for 1 amp but it was enough for my Pioneer deck. The only downside is that the PAC adapter does take up some room, so you will have to be careful to move things around so there is room behind the deck when you slide it back into the dash. Oh, and the steering wheel controls work perfectly with my Pioneer, too. I thought $79 was pretty expensive but it did save me time, make the install very easy, and allowed me to continue to use my steering wheel's stereo controls. So, in retrospect, I'd definitely buy it again.

Pros: Makes installation very, very easy. Steering wheel controls are usable!

Cons: A bit bulky, requiring careful arrangement of where the PAC adapter fits behind the dash.

This went in a 2013 VW Jetta TDI and worked fine with an Alpine and then a Kenwood. I'm sure theres a way for the back and forward buttons on the steering wheel to scroll through presets but thats not the way it comes setup.

2011 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

This product allowed me to retain my 2011 VW Jetta SWC with my new Kenwood head unit. The instructions were adequate for me to get things going the first time, but I have quite a bit of experience with electronics and this type of installs, so your mileage may vary. The unit came with everything I needed to connect the Kenwood harness to the VW connector in the dash. The default program supported basic volume, next/previous track and radio station switching, but not the phone control. When changing my VW Multifunction Display mode from MPG to Time or speed display the head unit changes folder when in the USB mode which is not desirable in the least. The PAC device is made for many car models so I can expect there to be some imperfections out-of-the-box. Luckily PAC foresaw this problem and allows you to reprogram each button to a specific function. If you want to retain all SWC functionality, and want to avoid weird things happening when you press buttons, you may want to reprogram the unit, so plan on it before you close everything up like I did. Overall, I'm happy with the PAC unit and would recommend it to VW Jetta owners.

Pros: Flexible programming interface that allows custom configurations to suit specific needs. Comes with everything needed for installation. Works well.

Cons: Instruction manual may not provide enough information for inexperienced installers.

Verified employee purchase (What's this?)

Easy plug and play. I don't have a Steering wheel control so I cant say anything about that. I have a 2003 VW Jetta with the Monsoon system. I have always read about people car battery draining after a new head unit install. That's because the monsoon factory amp doesn't have a remote turn on wire. I uses a low voltage signal from speaker wire. But for the amp to turn off it needs to ground out. That's where this device comes in. no dead battery.

Pros: works like a charm. killer discount when you buy a head unit from Crutchfield

Cons: have to butt connect wires or solder. finding a place to tuck it away behind dash.

Worked great. Instructions were sparse, but a little time to get it right was worth the investment.

Pros: Steering wheel controls worked great, easy to program. Love the speed output and reverse output. Made wiring those into the radio MUCH easier.

Cons: Lost audio menu on Steering Wheel control. Wish this kept the audio menu in the multifunction display so it wouldn't trigger station changes when I really just want to see my average MPG. FW update?

Perfect adapter for VW but confusion on need for SWC adapter in VW without SWC functions

Pros: Outstanding build qualty and adapter

Cons: Very poor instructions for wiring and Steering Wheel Control (SWC) on vehicle with no SWC; need instructions to be consolidated rather than multiple conflicting instructions

This is why I love buying from Crutchfield...they have everything I need to make my install quick and painless and saves me the time from shopping around for custom installation parts.

Pros: Worked without any further modifications

Cons: A little on the bulky side, made fitting all the wires, adapter, and control box back into the dash with the DD receiver a chore. Would benefit from a plug N Play type of between harness and radio deck

Perfect fit. No need to cut the factory wiring harness. The only thing that took so long to install was conecting it to the radio harness using solder and shrink wrap for a professional install look. Great product.

Pros: Everything about it.

Cons: Nothing about it.

Works as promised, but be careful!

Verified employee purchase (What's this?)

2003 VW Passat Wagon GLX 4MotionDevice works as promised. Steering controls volume and radio, cd, bluetooth/pandora and iPod flawlessly.

Pros: Does everything it is supposed to do. Installation requires attention to detail. Take care of the easy ones (speakers, power, antenna, etc.), and the hard ones (remote, illumination, and the blue wires) become easy too!

Cons: To paraphrase Sherlock Holmes, "eliminate the impossible and the results, no matter how improbable, must be the truth". There are connections that are easy (simple color matches). Tackle those first. The remaining connections may be on the Navigation trunk or those pesky blue cords (remote, antenna, etc.). Also, if you use butt connectors and heat guns, you run the risk of melting the unit. I did, but it still works. Lastly, as others pointed out, there is a lot of bulk behind the HU!

Tee adapter interfaces the steering wheel controls with the aftermarket stereo. Allows for factory settings or to reprogran switches for other functions. The adapter was simple to install, however, could use a better wiring diagram to ease in the installation.

Pros: Simplicity, size, function

Cons: better wiring schematic.

necessary evil

Dave from E WVa on 7/26/2013

2004 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

It's a shame that some factory stereos require a 3rd-party addon like this in order to use an aftermarket stereo. Once you start accepting that, this device works as advertised. As a bonus, it lets you keep your steering wheel audio controls (if your car has them). And it DOES work in a VW Jetta, at least the Mk4 series with the Monsoon system.

Pros: Does exactly what it says on the box. Has all the documentation for getting it to work with all major aftermarket brands.

Cons: Bulky; had to cut some supports out of the dashboard in order to make room for everything. Not crazy about the price either, but at least Crutchfield gives you a big discount if you buy this with the radio.

I installed this into a 2009 VW Jetta TDI with a Bluetooth after market head unit. The steering wheel controls that interface to the PAC unit worked perfectly the first time. I would highly recommend this interface unit to anyone replacing their OEM unit and want to keep the steering wheel radio and phone controls working with their new radio head unit.

Pros: Easy plug and play installation, compact unit fits behind the new head unit in the dash with now problems.

Cons: None, even the price isn't bad

Installed this in my 09 Jetta with the new head unit. Made all factory interfaces with the OEM unit work flawlessly. I took the time before installing to solder all wire connections to the OEM wire connection adapter and head unit wire harness so install was literally plug and play.

Pros: Makes all OEM functions work with new head unit. Easy install

Cons: Directions can be confusing as it is an all in one unit and has settings for multiple different manufacturers. A bit pricey (if you wait to buy it separately)

Blade from Gilbert, AZ on 5/5/2013

2013 Volkswagen Jetta

Verified customer (What's this?)
Verified employee purchase (What's this?)

I've never installed a car stereo before. In addition to this harness having the steering wheel controls, it also had the wires to send the power on signal to the amp/sub even though I have can bus. It prevented me from having to built some wacky fuse tap (insert mass confusion here) Everything worked the first time and my install is amazing. programming for SWC is possible.

Pros: all-in-one for my MK6 VW Jetta clear instructions includes SWC programmable

Cons: on bundle of wires marked as "nav system" when two of the wires were necessary for systems OUTSIDE of the nav system, confused me for a long while. sort of expensive for a harness SWC programming instructions aren't too clear on the steps.

Gave it only three stars because some of the functions won't work correctly. Spent a long time with Crutchfield support. The steering wheel buttons work and nice having use of the "phone" button on the wheel. It is not putting out the P-brake signal, reciever shows it the brake being "on" all the time. It makes 1/3 of the Alpines features useless untill the car is driven a ways. Need to run the reciever's P-brake wire directly to the PB switch itself. Wished it had a foot brake wire coming out of the box too, but would it work correctly?

Product Research

Features

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

Passat 2002-2013
Rabbit 2006-2011
Tiguan 2009-2013
Touareg 2005-2010
Notes:
  • 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.

# Dial Radio Manufacturer
1 Alpine
2 JVC

Note:

  • 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.

Multi Function Display (MFD) Compatible: When used in any of the following vehicles equipped with a Multi Function Display (MFD)..

  • 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.
