You'll only be able to retain your steering wheel audio controls with a compatible car stereo made by Alpine, Blaupunkt, Clarion, Jensen, JVC, Kenwood, Pioneer, or Sony. No other brands are currently compatible. Check the Details tab to see if steering wheel audio controls are retained in your vehicle.
Crux's SWRVL-54 interface ensures that you can keep the steering wheel audio controls and the factory speaker system in your Volvo when you replace the factory radio. Connect this interface to the wires on your new stereo's wiring harness, and you've covered the power, ground, and factory speaker connections for your new stereo.
The SWRVL-54 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 adapter works with either amplified or non-amplified factory systems.
Note: Most vehicles will require additional installation parts please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.
I'm writing to reiterate that this works for another 2004 Volvo XC70. The outgoing unit was an HU-613. Incoming was KDC-X500. Everything works including steering wheel controls. I've confirmed through Crux, and it's worked for others as evidenced by reviews. Installation was straightforward. Highly recommended.
Pros: Maintains Volvo steering controls. Works as advertised.
Very easy component for installiation. Straight forward on the wiring diagram. Good product manufacting also. Would use again.
Pros: If you're installing a stereo on your newer model Volvo this is the kit for you. Very easy to use.
Cons: No cons here
Very easy to connect. But requires patience.
Was skeptical to try this part out as Crutchfield's vehicle fitguide said that this wouldn't fit my '04 XC70 but it fit perfectly and this was the only part I've found out of a few that would interface with the steering wheel controls! Hooray! I had tried two other CAN adaptors and none would read or work with the car. This part also had a lot nicer wiring harness than what I had put in it previously, so that was a plus as well and it more than cleaned up a lot of my wiring mess.
Pros: Pretty much plug and play and provides SWC and a few other awesome functions for fancier stereos.
Cons: Couldn't drive and pick this up the same day I ordered it! :P Crutchfield's Vehicle Fitguide lies and says that this isn't compatible with a lot of Volvos but you should trust the item description more since that's what I did and it worked like a charm just as the description had said.Crutchfield response on February 23, 2015 Thanks for the info. We'll confirm with Crux that the SWRVL-54 is supposed to work with the XC70 and then correct our database. Glad to hear it worked out for you!
Bought this for a pioneer system for the wifes Vlovo
Pros: Workes great
Great solution -works like a champ!
Pros: All original SWC features work flawlessly! Was easy to do all the connections with the aftermarket Stereo's wiring harness in the house on the table before going out and installing it all in the car.. everything was clearly marked - didn't use the auto antenna wire or the illumination wire as not an option with this vehicle.
Cons: I could find no real cons...
Solved a long time problem for my 2005 XC70- was able to restore original steering wheel volume and scan control to aftermarket HU
Pros: Easy to install- Immediately recognized vehicle and HU
Cons: Only basic controls are supported but this is all that was originally offered in the car
I purchased this adapter for my 2004 Volvo S80 to be used with a Pioneer AVH-X8500BHS receiver. It does a great job of enabling the factory steering wheel controls. In my vehicle I only have track advance and volume controls. It appears to be the only product currently on the market that will interpret Volvo's CANBUS signals for this purpose. The signals provided by the converter include speed sensor and illumination, which are not listed in the manual. I was unable to check the functionality of the speed sensor because the Pioneer head unit does not use it. The illumination wire is supposed to be tied to the vehicle's day/night auto-dim sensor but it always output 12 volts regardless of ambient lighting conditions. It is convenient that this assembly is a plug in solution to the factory harness and picks up the needed power, ground, and signal wires. I removed the gray connector as I was using preamp RCA lines on the head unit. I also removed unneeded wires from the radio connector to minimize the wire bundle thickness. The unit is small enough so I could tuck it out of the way. Upon powering up the head unit I was glad to see the steering wheel controls working as expected. The only shortcomings I could find were that the lack of information in the manual about the actual wires that need to be hooked up, and how they are implemented. I also had difficulty with the small 3.5mm plug harness being too short compared to the rest of the wiring during installation.
Pros: Nearly a plug and play solution to an otherwise impossible SWC challenge with VOLVO's unusual CANBUS wiring.
Cons: Documentation is doable but lacking in detail, and does not depict all wires in the harness. Functionality of illumination wire appears to be dependent on model and year of vehicle - this is not described in product documentation.
Volvo Radio Replacement Interface: The CRUX SWRVL-54 is a radio replacement interface for select 1999-2012 Volvo vehicles. It facilitates the integration of an aftermarket radio to enable retention of select factory features when replacing a factory installed radio in select Volvo cars. This interface is also pre-programmed for retention of steering wheel controls.
Compatibility: The CRUX SWRVL-54 is supported by the following 1999-2012 Volvo vehicles; with non-amplified or amplified factory audio systems. (Only retains factory amplifier in select vehicles.)
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 SWRVL-54 also features a steering wheel control output for Pioneer, Sony, Jensen, Alpine, Clarion, Kenwood, JVC, and Blaupunkt 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 SWRVL-54 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 (labeled - Pioneer/Sony and Alpine/Clarion/Kenwood/JVC). You will only plug in one of these connectors to the interface module, based on the type aftermarket head unit you are installing.
Navigation Outputs: The CRUX SWRVL-54 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 SWRVL-54 provides an amplifier turn-on lead for your vehicle's factory amplifiers (when applicable).
Wiring Harness: The included wiring harness features two 12-pin connectors which plugs into your vehicle's factory radio harness, plus a 12-pin connector which plugs into the SWRVL-54 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.

Heard great things about this if you own a Volvo and want to keep steering wheel controls. Also have heard that the harnesses themselves are nicer than those from Metra. [ Jon Jan 27, 2016 ]
