Installation Note: Click here or call an Advisor at 1-888-955-6000 to see if the SWI-X adapter is compatible with your vehicle.

You want to install a non-factory replacement radio in your vehicle, but you hate to give up the convenience of your factory steering wheel radio controls. PAC's SWI-X interface allows you to connect your steering wheel controls in a wide variety of vehicles to almost any aftermarket stereo with wireless remote capability.

Installation is straightforward — connect a few wires, then program the adapter for your particular car and your stereo, and you'll retain the convenience of your steering wheel controls. The SWI-X uses an infrared beam to communicate with your stereo. Step-by-step LED confirmation makes programming easy. Once connected, the adapter's memory will learn up to 12 functions from your receiver's wireless remote, retaining them even if battery power is interrupted. Dimensions: 3-3/4"W x 1-1/16"H x 1-9/16"D. Warranty: 1 year.

Important Note: You'll want to make sure that your stereo and your vehicle are both compatible. If you have no car audio installation experience, you should consider professional installation. The SWI-X uses an infrared beam to communicate with your stereo's remote eye — check "Details" for a list of incompatible remote controls or call an Advisor at 1-888-955-6000 to see if this adapter is compatible with your stereo.

What does a steering wheel audio control adapter do?

Many people aren't thrilled with the sound of their car's factory radio, but don't want to replace it because they'll lose those convenient audio controls on the steering wheel. For most vehicles, you can purchase an adapter that allows you to use those controls to run a new car stereo, so now you can have great sound and convenience too. Even cooler, if your new stereo has iPod controls, you can use your steering wheel controls to run your iPod.

I have installed an aftermarket stereo before and had little trouble until I purchased this item. I ultimately had to take this item to a professional to install, who refused to install this particular type of unit due to functionality problems and user complaints.

Crutchfield Customer Review (What's this?)

Works very well. Installation pretty smooth, however the included listing for devices and settings is printed so small ANYONE needs a magnifier to read it. Need to drill a mounting hole for infrared emitter, but seems they don't even know what size it should be. Would help to ensure a good fit.

SWI-X better than SWI-JACK or SWI-PS?

Written By RogerK, Hamilton, Canada on Saturday, October 10, 2009

I think this unit may be better than the SWI-PS or SW-JACK models, even if it requires the IR eye. Let me explain:

1 - Pioneer head units use up/down buttons for radio preset surfing, but left/right for track forward and back. SWI-PS maps steering wheel up/down to left/right. Great for CDs, terrible for radio. SWI-X allows you to map how you'd like, provided it's on the unit's IR remote.

2 - SWI-PS can map up to 9 functions. Volume Up, Volume Down, Mute, Track Up/Seek Up, Track Down/Seek Down, Source, Preset Up/Disc Up, Preset Down/Disc Down, Band. No Bluetooth, or off-hook button. SWI-X can have any 12 functions(or less) on the deck's remote on your wheel.

3 - If you decide to sell your deck, the SWI-X is likely compatible with your new one. SWI- PS is for Pioneer/Sony, and SWI-JACK is for JVC, Alpine, and Kenwood. Going from Pioneer to Alpine would require a new unit unless you had the SWI-X.

So I installed a SWI-X this time around. My Mazda6 to FH-P8000BT buttons are mapped like this:
vol up = vol up
vol down = vol down
up = up (preset up, folder advance)
down = right (track advance)
mode = source
mute = Bluetooth off-hook(to answer incoming calls)

This remote for your steering wheel is not worth the effort required to install it. It was a pain not only to install, but even harder to program. For the average "do it yourselfer", I can deal with just about anything except soddering transistors simply to have steering wheel volume and tracking controls!

Crutchfield Customer Review (What's this?)

Installed in 2001 Honda Accord; head unit Panasonic CQ-RX400U. The first SWIX sent had a double-led-on fault alert. Crutchfield exchanged it for a new one. Second unit accepted the programming. I was going to install the IR emitter in the console box just under the lid; too low by two inches for the IR on the head unit to read. I ended up moving the swix unit to just above the brake pedal area under the dash... then I had enough IR emitter lead to run up the A pillar, under the headliner to the exit/entry handle on the roof just inside the door. I put the emitter in a small hole in one of the rubber screw caps on the handle and it's almost un-noticeable. The IR path is in front of the driver and works 100% all the time. The install takes some time; it's worth it if you really, really want those steering wheel controls back. 4 out of 5 because of vague install instructions. Crutchfield customer service, however, was GREAT and cleared up the install issues.

Downloading the PAC vehicle specific instructions is a MUST.

Crutchfield Customer Review (What's this?)

The sensitivity for the IR Extended Mode is a joke. I have about a 1 inch range for the thing to actually work and that requires the IR node to be sticking out of the console. Don't waste your time with this if you have a G35, just use your remote.

Crutchfield Customer Review (What's this?)

So, I have a '99 Pontiac Grand AM SE, with a Jensen VM9311TS headunit. Crutchfields fitment guide said this module would not work however after calling it does work. So I ordered it and the install was pretty simple, only slight issue was getting it programmed but after reading through it once I relized I was looking to hard into steering wheel button release, press remote button that you want to have function and then back to steering wheel press release and then remote...that simple.

Tough banana

Written By Sheri, Long Beach, CA on Sunday, June 01, 2008

Crutchfield Customer Review (What's this?)

So, first we had to figure out the wiring thing, THEN we had to solder on resistors to the wires! What a mess. A plug & play option would have been so much easier and faster... but no, they don't make one for my car. Bummer. So after we got it soldered together (the whole time praying it would work and not catch on fire), THEN we had to program it. Thank god they had a website where you pick your car and it gives you vehicle specific programming info, otherwise I think I would have chucked it out the window. SO then, it only took like, 10+ tries to get the thing programmed correctly. The directions were VERY vague. But I got it to work... finally. There is a slight delay between pressing the steering wheel controls and having the radio register it, but I think that's because it has to send an IR signal to the radio. But it's better than nothing I suppose. I personally don't think it was worth the headache to install it though. I could have lived without my steering wheel controls. =P

Crutchfield Customer Review (What's this?)

I was skeptic and figured I would be cutting, splicing, etc.. a lot of wires.
Well, the power, ground, and green wire was all I need. Install was a snap,
programming took a few tries to get used too. Once you figured it out, it
was a breeze. I went to the website to get directions for my vehicle. I
didn't even bother with the ones in the package. I am testing the IR
sending unit in a few spots before I mount it. I am actually planning on
putting it in the dash below and to the left of the deck on a removable
panel out of site. We will have to see how it works on a sunny day.

Harley was a very good and informative sales person.

Easy Install, works well.

Written By Ian, Tempe, AZ on Saturday, February 23, 2008

It worked with my vehicle, 1999 Accord, even though Crutchfield's site said it would. Mostly easy install, only hard part is figuring out which wire is from the steering wheel. The programming is a bit difficult and took several tries to get working properly. The response is a bit sluggish in response time, to get faster result have to hold down the steering wheel button at times.

Well installation was a snap with just 3 wires although I had to determine the signal wire because the application guide did not have my year and model together. Programming guide was just wrong. I had to skip ½ the steps to get the device programmed.

Works all my steering wheel controls as good as the remote.

Wiring chart doesn't match vehicle's?

Written By mpcruiser, Winchester, TN on Sunday, February 03, 2008

Crutchfield Customer Review (What's this?)

It doesn't work @ all - I even took it to a professional installer & PAC distributor in Tullahoma, TN. They said the wiring diagram supplied with the PAC unit did not match the 2001 Nissan Pathfinder's steering wheel control wires (1) was missing - they are reseaching it to resolve problem "but" if you can help me "Please" advise!!! This was a gift to my daughter for Christmas & to retain the steering wheel controls is the reason choose the equipment I purhased by the advice of one of your online sales rep. (we even talked by phone). I very much would like to make this work!!! It is installed correctly & the installer has 21 yrs. experience, he said that the wiring schematic just did not match & even checked date of mfg. of the Pathfinder which was (07/2001)!?!?

Steering Controls

Written By Webbsite, SLC, Ut on Friday, December 28, 2007

The programming instructions are very tricky and poorly written. 30 minutes to install and 2 hours to figure out the programming. Was disappointed that all factory functions could not be programmed for the Toyota. Also no factory to PAC cable adaptor provided. You have to cut the factory wires to make the connection. Granted that is only three wires but it reduces the installation to being very messy. What functions it does provide work very well, better than the factory. 3 of 5 because it is better than nothing.

Works GREAT in my 2006 Sonata

Written By michael, NY on Friday, October 12, 2007

My one hesitation in putting in a new HU was that I would no longer have the steering wheel controls. Well even though Crutchfield did NOT think this would work in my 2006 Sonata with sub w. it did work!!! I called PAC tech support directly and asked them if it would work. They were very helpful and told me exactly which wires to use and which harness pin locations they should connect to.

As all of you with the 06 Sanata know there is NO button on the steering wheel for ch up /down. With this SWI-X I changed the Mute button to function as a Ch Up button.


Written By Tim, Northern Virginia on Thursday, June 21, 2007

I was somewhat skeptical about this product given some of the reviews on this site and others. I needed it to retain my factory Steering Wheel Controls on my 2003 GMC Sierra pickup. At first, I was a little confused by the printed instructions that came with the product, but after calling Crutchfield, they pointed me to the PAC-Audio web site. From there, I went straight to the automated tool for my specific configuration. The custom instructions it generated were much better, and within 15 minutes, I was up and running. The LED worked so well it's not even pointed directly at the unit and it works perfectly. No resistors needed either. Programming was a snap. PAC has turned me into a believer, and I will certainly go with them again if I need an adapater. Well worth the price!

The only reason I'm not giving them a 5-star rating is because they need better tech writers for their printed materials which were VERY confusing and were different than those generated by the Web Tool.

Works great with Clarion in my '06 F-250

Written By Jay, SE Florida on Monday, February 05, 2007

After much research and being told that it would not work in my '06 F-250 or with my Clarion in dash DVD, I ordered the interface and installed it. Took less than 30 minutes to install. Most of the install was removing the dash. I found the instructions very easy to understand and it programmed very easily and quickly. Works absolutely perfect with my setup. Installed the infrared emitter just to the right of my head unit next to the in dash power point. It seemed to work well anywhere on the dash as long as it was not behind the head unit at all. One downside I see is that the cable length for the i/r led is pretty short and would not allow you to run it to the over head console or anywhere besides the dash. Great Product and I'm thrilled to have my steering wheel controls back!

Directions were vague, the delay is somewhat undesirable, and I feel the unit is overpriced. After the installation I guess I was satisfied as I couldn't live without my steering wheel controls.

This product works great except when sunlight is directly hitting the transmitter. I installed it between the radio and the climate control of my 2006 Silverado. It looks like it belongs there. Overall I would recommend this product.

bought this paper weight and started to install it... my stereo wouldn't pick up the signal... thinking i was doing something wrong i aimed the ir transmitter at my roommates truck and it worked fine... after crutchfield i called the manufacture. they had no idea.. so being that i had a paper weight i decided to figure something out... as i was getting frustrated from it not working my roommate closed the garage door. as soon as the door block the sun from shinning in the path of the signal it worked perfect. had him raise and lower it a few times with the same results. works great at night though or when your in the dark...

Mixed Emotions (And Instructions)

Written By Steve, Boston, MA on Friday, January 27, 2006

Crutchfield Customer Review (What's this?)

This is the only option I had for my 2002 Freelander. All things considered I think its over-priced for a simple IR repeater.

The instructions for my vehicle were wrong (both from crutchfield and on the manufacturer's website).

And maybe this is the case with all products of this type, but the lag between pressing the controls on the steering wheel and result on the radio is annoying.

But, like I said, its not like I had any choice if I wanted to keep using my on-wheel controls

Keep your Steering Wheel controls!!!

Crutchfield Customer Review (What's this?)

Purchased the PAC SWI-X unit to go with my new Alpine CDA-9851 head unit and let's start out by saying read the little yellow slip of paper that comes with this unit and go to the pac-audio website and get the instructions for installation for your specific vehicle and throw away the ones that come with the unit because they are useless and the website has everything you need to correctly install this unit into your vehicle! Good unit is a little cumbersome to program and get used to but does the trick. Design could have been better so you didn't have to use the remote lead but I was able to keep it close to the unit so that it works. Biggest thing is you get to keep your steering wheel controls and program them to do anything you want. That is a nice feature.

I absolutely love this product. I have it installed in my 01 Accord EX V6 and it works perfectly with my Kenwood headunit. I was able to program this unit to control functions differently than what Honda had intended for the buttons. I can now navigate through my entire MP3 collection on my Kenwood Music Keg without taking my hands off the wheel, which is awsome.

Works Great- 2005 Chevy Silverado

Written By Josh, Boise, ID on Sunday, October 16, 2005

Crutchfield Customer Review (What's this?)

At first I was a little confused about what wire to use on my 2005 Chevy Silverado, but after a quick visit to the manufacture's website they had color photos and step by step instructions specific for my vehicle. After finding the right wire in my truck the installation was super easy! This product worked great for me, and I mounted the IR sending unit in the over head console. The wire was a little short wich made it difficult to route the sensor, but the response time is very quick. I would have given this a 5 star if the cable was longer and I didnt have to mount the box behind my vent- but that is just for my truck. I love it!

Less than impressed

Written By Gregory, Sarasota, FL on Sunday, June 19, 2005

A great idea with poor execution. After spending about 2 hours troubleshooting the installation of this product and trying to figure out why it would not accept programming, I did a little experimentation. It turns out that the instructions for my vehicle, a 2001 Honda Accord Coupe are incorrect. They tell you to install a resistor when one is not needed. After removing the resistor, programming went smoothly, but operation is less than desirable. There is a pretty large delay (1-2 seconds) between when a button on the steering wheel is pressed and when the head unit actually responds. Buttons also will not work sometimes unless the steering wheel is turned. After browsing the manufacturers website it appears that the resistance can change as the wires in the steering column are turned with the steering wheel which causes undesired operation. I followed the recommendations of changing the programming with no improvements. My advice...learn to live with using the manufacturers wireless remote. The new hard-wired versions may work better, but I would not recommend this to anyone.

Product Research


Compatibility: The SWI-X interface allows you to retain the use of your steering wheel radio controls when replacing the factory head unit with an aftermarket radio with IR remote control in select GMC, Chevrolet, Pontiac, Buick, Cadillac, Ford, Lincoln, Mercury, Acura, Honda, Audi, BMW, Jaguar, Mazda, Mitsubishi, Nissan, Range Rover, Saab, Volkswagen and Harley Davidson vehicles. The interface allows you to use the radio controls in compatible vehicles to command most aftermarket radios with wireless remote capability. The SWI-X interface will only work with infrared remotes that use a 38-40kHz carrier frequency.

Wiring Advisory: You'll usually have to hardwire this adapter into your vehicle's wiring. In most vehicles, the factory radio plug does not have a wire dedicated to the steering wheel audio controls, so splicing is often required. PAC does provide custom wiring instructions for all confirmed compatible vehicles on their website.

Incompatible Remote Models: The SWI-X interface in known to be incompatible with the JVC RM-RK230 remote (included with the JVC KD-AVX1 and KD-DV5100 head units), the JVC RM-RK240 remote (included with KD-AVX2), RM-RK241, and RM-RK250, and the Sony RM-X110, RM-X112, RM-X131, RM-X143A, and RM-X145A infrared remotes.

Easily Programmable: The SWI-X is easily programmed or reprogrammed using the factory controls and the head unit's remote control. During programming, step-by-step LED confirmation will guide you. Once connected, the SWI-X's memory will learn up to 12 functions from your receiver's wireless remote, retaining them even if battery power is interrupted.

Resistor Kit: Some vehicles have a separate wire for each of the steering wheel buttons. Use the resistor kit for steering wheel push buttons that do not already have a resistor network connected to them. The resistor kit includes the following resistors:

  • 47 Ohms (yellow, purple, black, and gold bands)
  • 150 Ohms (brown, green, brown, and gold bands)
  • 560 Ohms (green, blue, brown, and gold bands)
  • 1000 Ohms (brown, black, red, and gold bands)
  • 1500 Ohms (brown, green, red, and gold bands)
