Meh...at least I can still change the volume from my steering wheel.

On my 2004 XC70, this allowed me to keep my volume controls, but I can't use the channel preset buttons as designed. Now the steering wheel button just changes frequency ( 90.5, 90.5, 90.7, etc.). It SHOULD change presets. Tech support said this was the best I'd get. Pretty pricey for something that only half works. Luckily, the Crutchfield guarantee will allow me to replace it with the cheaper harness if I want. I used Crutchfield to wire the interface which was worth every penny.

If you own a 2004-2012 volvo you need one

If your a p2 owner and want to add a head unit this is by far the only way to go, yes the box is a tad. If and a pita to locate, it beats the joke of the other adapters, not only for h.u but steering wheel controls and keeping the factory amp.

Gets it done

The wiring interface is pretty good. It gets the job done and the radio is now working fine. HOWEVER... There are a LOT of wires to connect to the harness for the radio, so get your splicers and crimp tool ready. Lots of options that you may or may not use depending on the unit you buy and I had a couple of wires that were difficult to positively identify.

CRUX SWRVL-54 Wiring Interface

Well built unit and harness that does everything it needs to for virtually any head unit. The singular downside is, unfortunately, a rather large one. The central "box" that everything connects to is pretty big, relative to everything else, and finding a home for it, alongside all the other factory and aftermarket wiring, so that the new head unit fits properly was a tough task, and required the modification of the stereo install kit.

Once we saw this review, our Tech Support specialist, Roman, reached out to James to help him further. We'll either help him get the wiring interface working the way it should or help him return it for an exchange or refund.

Perfect Interface

I purchased as part of the ready harness service to ensure my steering wheel controls worked with my new floating Apple CarPlay receiver. The wiring and interface work perfectly. The ready harness service reduces the time to install, leaving me more time to find the screws I have dropped behind the dash! Ha. Seriously, this is a well made product which I endorse

Crux Wiring Interface for Volvo V70

I understand that there are other wiring interface kits out there, but this is the one that Crutchfield had for my application, which I utilized to install a Pioneer MVH-S622BS head unit in a 2007 Volvo V70. I am old school, and really expected to be able to adapt the wiring harness to the head unit harness using the supplied paper instructions, but nope; you need to really read the email that Crutchfield sends you, which contains a nice link to a page that has a color coded chart showing you which wires on the interface wiring connect to the head unit's wiring, and also to the vehicle amplifier (if it has one, mine does not). To splice the wires together, I used the classic "Western Union" style with each stripped wire end in an L shape and then twisted around each other to form a constant section and good mechanical connection, then soldering and following up with wire shrink wrap to insulate. The steering wheel control uses one of two supplied harnesses, depending on head unit manufacturer, and simply connects between the supplied adapter box and the radio using a jack. I did all the connections on my kitchen table, and after installing the head unit in the dash adapter, it took 5 minutes to plug everything in, insert the dash adapter in the car, and install the retaining screws. Hooked up the battery and initialized the head unit, and now I have lovely music again. Very pleased, 4 stars.

Doesn't work

Bought for sole purpose of retaining my steering wheel controls and it doesn't work. I triple checked everything and its all hooked up properly but still doesn't work. Everything else works fine but I could've saved $80 with a regular harness. Waited 45 mins on hold with tech support then gave up.

Great Integration in '07 XC70

Worked great in my '07 XC70. Made wiring everything up very straightforward, everything was labeled well and made for no guess-work with anything wiring related. Used the reverse output to trigger my head-unit to enter reverse camera mode, steering wheel controls work, couldn't ask for anything more (other than getting the back-up sensor beeps back).

Great product and support

I originally bought my install accessories and radio online. I should have come to Crutchfield originally! I had nothing but problems installing the radio and getting SWC to work based on using product recommended by the other retailer. Big mistake. I finally called Crutchfield and the support staff was great. Provide exactly what I needed and provided a discount due to problems I had. I will not buy from any other supplier in the future.

CRUX SWRVL-54 Wiring Interface

The CRUX SWRVL-54 Wiring Interface works great on my 2003 Volvo V70. BB was installing a Kenwood A/V head and tried two other interfaces that did not work to give me the steering wheel controls. I searched hard and found this Crux unit. Works great and gives full steering wheel controls. The BB installer said it was easy to install and has since used it on two other Volvos with great results! Highly recommend for Volvos Crux lists!!

Another confirmation that this CRUX SWRVL-54 interface works with a 2004 Volvo Xc70 . with (CAN) data factory radio was an HU-613. installed a non listed Android radio with 3 wires for steering wheel control input. I worked with Paul in Customer Support, he spent a good mount of time looking into my specific questions on my install, very Satisfied customer. thanks again Paul! key 1 key 2 and ground. easy to install radio lights work with headlamp switch, but do not dim. radio will stay powered up until key is removed from ignition. a few attempts were needed to set dip switches for this particular radio.

Worked Perfectly

Pioneer AVH-4200NEX install in 2004 Volvo XC70 with HU-613 and steering wheel controls maintained (even though it's not listed as a supported item for my vehicle)! I loved being able to prewire outside of the car in a comfortable environment first. Then just plug in and the wiring is done.

Easiest way to install a radio into a Volvo

It doesn't get any easier than this. I used the CRUX SWRVL-54 to install a SONY XAV-AX100 Android Auto/Apple Carplay head unit in my daughter's 2007 Volvo XC70. It's like a whole new car. Matched up the colors and everything just worked -- can't say that about other steering wheel control interfaces. I wish that such a simple option was available for my other vehicles. It was frustration free experience. Best of all -- you don't have to cut/tap/splice any of the wires in your car's harness to use this adapter.

works, even though the site says it does not. Follow the manufacturers documentation and not Crutchfield. I do wish that I could remap the buttons to different functions, but there's a limited market for Volvo SWC adapter boxes, and this one is far more reasonably priced than the alternative. I'm happy, my wife is happy, everyone wins.

Works with 2002 V70 and Kenwood KDC-BT362U

Critchfield tried not to sell Thad to me. They kept saying that it wouldn't work on my 2002 Volvo V70. But I read the instructions and they said it should work for P26 type, 2nd Gen vehicle. So after talking with customer support to try to confirm this, it finally boiled down to try it, you have 60 days to return it if you aren't satisfied... So it's installed, and the steering wheel controls work controlling my new Kenwood BT362U. I'd give it 5 stars except for the poor documentation on what vehicles it actually works with.

Another successful install on 2004 XC70

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.

Awesome Part

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.

Good solution for Volvo owners

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.
