Our take on the CRUX SWRVW-52 Wiring Interface

by Dave Delamere
CRUX

Wire in a new radio

Crux's SWRVW-52 interface ensures that you can keep the steering wheel audio controls and the factory amplifier (if present) in your Volkswagen when you replace the factory radio. Once you connect this interface to the wires on your new stereo's wiring harness, you've covered the power, ground, and factory speaker connections for your new stereo.

The SWRVW-52 interface also offers the reverse, illumination, and Vehicle Speed Sensor (V.S.S.) outputs that you'll need if you're installing a navigation receiver. The Crux interface is designed to work with the factory Volkswagen CAN-bus systems.

Note: This interface will retain steering wheel audio controls when used with Alpine, Clarion, JVC, Kenwood, Pioneer, or Sony receivers.

Features

Volkswagen Radio Replacement Interface: The CRUX SWRVW-52 is a radio replacement interface for select 2002-up Volkswagen vehicles (w/ CAN bus systems). It facilitates the integration of an aftermarket radio to enable retention of factory features when replacing a factory installed radio in select Volkswagen cars (with or without factory-installed amps). This interface is also pre-programmed for retention of steering wheel controls.

Compatibility: The CRUX SWRVW-52 is supported by the following 2002-up Volkswagen vehicles with CAN bus systems and non-amplified or amplified factory audio systems.

Note: Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible and what additional installation accessories will be needed.

Steering Wheel Control Retention: The CRUX SWRVW-52 also features a steering wheel control output for Alpine, Clarion, JVC, Kenwood, Pioneer, and Sony aftermarket head units. The steering wheel control output consists of a right-angle 3.5mm connector and a light blue/yellow wire (use the connection that your aftermarket head unit is fitted with). The SWRVW-52 interface module will work with any of the listed aftermarket head units, by setting its three dip-switches (see owner's manual for appropriate setting).

Note: The steering wheel control harness features two 4-pin connectors, two 3.5mm connectors (labeled Pioneer/Sony and Alpine/Clarion), and one blue/yellow wire (labeled Kenwood/JVC). You will only plug in one of the 4-pin connectors to the interface module and one of the 3.5mm connectors or blue/yellow wire into your aftermarket head unit you are installing.

Navigation Outputs: The CRUX SWRVW-52 radio replacement interface module provides a VSS (vehicle speed sense) and a Reverse Gear output to make installing an aftermarket Navigation radio simpler and less time consuming.

Amp Turn-On: The CRUX SWRVW-52 provides an amplifier turn-on lead for your vehicle's factory amplifiers (if equipped).

Wiring Harness: The included wiring harness features a 40-pin connector which plugs into your vehicle's factory radio harness, plus a 12-pin connector which plugs into the SWRVW-52 interface module. The wiring harness also provides the following bare-wire leads which will need to be hardwired to your aftermarket head unit's wiring harness.

Works well

Written By Jonny, Ames, IA on Thursday, August 14, 2014
Crutchfield Customer Review (What's this?)
 
I had read that without this, the radio could drain the battery with the car off. Not sure how true that is, but picked it up anyway. The packaging says it doesn't support the factory fender amp, but mine is definitely still working. (Based on a little research, the factory amp turns on when 6VDC is on the front passenger speaker.) It was a little difficult to fit everything behind the stereo, but I got it all in WITHOUT breaking out any of the factory plastic. Overall a pretty easy install. My car doesn't have steering wheel controls, so I can't comment on that. Instructions were clear enough for me, but this isn't my first install. I think it's a bit overpriced for what it is, but I'm satisfied.
Pros:
Sufficient instructions, easy install.
Cons:
A bit bulky and pricey.

Crux SWRVW-52

Written By AndyB, Santa Rosa, CA on Wednesday, June 25, 2014
Crutchfield Customer Review (What's this?)
 
The adapter performs all of it's basic functions well. It simplifies the installation of a 3rd party receiver by allowing a direct connection to the factory wiring harness. It retains the function of the factory amplifier and subwoofer (My car has DynAudio and I wanted to retain this). It also retains the factory Steering Wheel Controls function... SORT OF. This is why I submitted a 1 Star review, like Michael from Arizona - None of my steering wheel control functions were mapped to the correct buttons. There definitely appears to be an issue with this adapter in SOME installations ?

So Ask yourself: Do you want to take a chance ... or should you just order another SWC adapter ?
Pros:
Basic functions work as expected.
Cons:
Steering wheel controls appear to work well for some, but not for others ... Do you feel lucky ?

It works as advertised, maintained my steering wheel controls with my kenwood DDX371. NOTE: you will still need to splice the wires from this with the wires out of your new headunit....make sure you pick up some 16ga butt connectors or something before you start the install
Pros:
works
Cons:
instructions could be a little more clear

perfect solution for vw with monsoon systems

Written By carytown, Richmond VA on Thursday, May 08, 2014
Crutchfield Customer Review (What's this?)
 
It works! Mates the replacement head unit with the OEM amp and speakers. The Monsoon system in my old 2003 Golf still sounded great. I just wanted to add some features like bluetooth phone integration, iPod, Siri hands-free and HD radio to update my vehicle.
Pros:
Turns the OEM amp on/off with key and head unit power so no battery drain. No running hot wires from the fuse box. Retains the VW stereo-on-until-key-removed functionality Very easy installation.

For the money not completely satisfied. The car has factory Bluetooth but the adapter does not utilize the factory microphone for the aftermarket stereo the phone button on the steering wheel doesn't activate the phone feature as I figure out the factory wiring I'll determine if they can actually improve their controller!

Great kit

Written By PeteM, Saint Paul, MN on Thursday, March 13, 2014
Crutchfield Customer Review (What's this?)
 
This adapter was used with a KenwoodDPX300U in a 2008 VW Jetta without steering wheel controls. The instructions were pretty straightforward. However, I did have a few questions about which wire from the Kenwood unit harness matched up with the Crux adapter. Particularly the power antenna adapter wire and the wire for the stock VW amplifier. Crutchfield's customer service was very helpful and had me soldering wires in no time. This adapter fits perfectly with the stock VW radio harness plug. Adapter and wires tuck in nicely behind radio and take up very little space. This adapter saves a ton of time, it will take you longer to solder the wires than it will to hook it up in your car.
Pros:
Easy to follow instructions and perfect fit to stock wiring harness.
Cons:
None.

If you have a VW - get this adapter

Written By sdj, Orlando, FL on Friday, March 07, 2014
Crutchfield Customer Review (What's this?)
 
I read a ton of reviews on this adapter on a lot of VW forums and I would say most are negative or that you simply don't need the adapter. While that may be true, this adapter is made the installation unbelievably easy and you don't have splice wires and run wires to your fuse panel, etc. Why would you buy a nice head unit and not get this adapter, which if you purchase through Crutchfield, is half price when combined with a head unit? I have a monsoon system in my car and wanted to retain the factory speakers and amp because they sounded great. Well they sounded even better with the Kenwood head unit and I was able to simply run one set of RCAs from the sub out plugs to my amp. Sound separation using the factory installed amp and speakers with MB Quart subs and amp is unreal. I have roughly $500 into a system that sounds better than most +$1000 systems. Don't be cheap, buy this adapter if you have a VW!
Pros:
Everything about it - made installation a breeze and the wire colors on the adapter match the wire colors on the new head units. Could not have been easier!
Cons:
None

CRUX SWR

Written By Michael, Arizona on Thursday, February 06, 2014
 
This unit did retain my steering wheel controls, but not as I had expected. Volume is now controlled by the Seek/Search buttons on my steering wheel, and Seek/Search is controlled by the phone buttons. The old volume buttons now control source and band. I called Crutchfield and Audionics, the manufacturer, and in both cases the technicians simply read to me from the instructions that came with the unit, which I had already studied. No one seemed able or willing to help me correct this disappointing malfunction.
Pros:
Steering wheel controls have been retained, though not as expected.
Cons:
Inadequate instructions. No way to reprogram or customize the controls.

Does what it's supposed to

Written By Hunter, Baton Rouge, LA on Sunday, November 10, 2013
Crutchfield Customer Review (What's this?)
 
Operates as advertised. Allows you to keep premium amps from OEM system. You do have to make sure you don't connect unnecessary wires (I.e. Steering wheel control wire if controls are not present and this will cause new head unit to ignore the remote).
Pros:
Works as advertised
Cons:
None
