Our take on the PAC SWI-CP5 Steering Wheel Control Adapter

You want to install an aftermarket stereo in your vehicle, but you hate to give up the convenience of your factory steering wheel radio controls? No problem.

You want to install an aftermarket stereo in your vehicle, but you hate to give up the convenience of your factory steering wheel radio controls? No problem. PAC's SWI-CP5 adapter allows you to use the steering wheel audio controls in a wide variety of vehicles to command select radios from Alpine, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, and Sony.

More features, easy programming

The SWI-CP5 adapter allows retention of steering wheel audio controls, rear seat audio controls, and retained accessory power (RAP) in a wide selection of vehicles. You can also assign two radio functions to each SWC button by using short press/long press functionality. The SWI-CP5 works in vehicles with either data or analog steering wheel control signals.

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. You can program this adapter with your smartphone, with your tablet or PC, from a USB flash drive, or manually. The direct connection to the stereo eliminates the need for an infrared emitter, allowing the adapter to function even in bright sunlight. Step-by-step LED confirmation makes programming easy. Once connected, the SWI-CP5's failsafe memory will learn up to 12 stereo functions, retaining them even if battery power is interrupted. Warranty: 1 year.

Important Note: On some vehicles, you may need a voltmeter to locate the correct wires to connect to the SWI-CP5. If you have no car audio installation experience, you should consider professional installation. The SWI-CP5 works with most Alpine, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, and Sony car stereos that have a wired remote control input or a dedicated steering wheel input.

Wiring Advisory: You'll usually have to tap into one to three wires in your vehicle at the radio location to connect this interface. If you're using a PAC wiring interface to connect your new car stereo to your vehicle, then it most likely will have a prewired connector for this PAC adapter so no wiring is required. PAC does provide custom wiring instructions for all confirmed compatible vehicles on their web site.

  • Steering wheel control interface module
  • 18" SWC harness
  • 6" USB extension cable

Steering Adapter is a bust!

Mickey from Universal City, TX on 4/19/2017

2003 Acura 3.2TL
Crutchfield Customer Review (What's this?)

I couldn't get this control adapter to work either. I managed to get some of the lights to light up when I press the controls on the steering wheel but nothing happens after that. No volume control, no ability to change the channel or stations. And the plug for what I am assuming is for my phone that I was advised to plug in last into the phone jack on the radio unit doesn't do anything. I can hear my phone ring on the unit but I can't talk through my radio. They sent me a mic with a very long cord but the mic jack I received is too little for the unit. So fed up with this thing. But too late to send it back now.

Pros: No pros

Cons: Crappy thing doesn't work.

Crutchfield response on 4/24/2017 Once we saw this review, our Tech Support team reached out to Mickey to help him further. We'll either help him get the adapter working the way it should, or help him return it for an exchange or refund.

Good product, bad instructions

Jessie from Baltimore, MD on 12/28/2016

Crutchfield Customer Review (What's this?)

Good product. Horrible install instructions. When all was said and done this product kept all my steering wheel functions in a 2010 camaro paired with a metra dash kit and Jensen vx7022. I did have to call crutchfield as one wire needed to be hooked up to a pink Hvac wire which I find odd but that enabled the unit to work. I guess if PAC had better instructions it would be a solid product.

Pros: Maintains all steering wheel functions

Cons: Bad instructions, no wiring diagram in paperwork provided. A lot of unused wires. PAC app not correct on car pin layout

Crutchfield Customer Review (What's this?)

Crutchfield told me download an app from the manufacturer to get the wiring diagram. The app wouldn't work on PC or phone. This is just a very complex universal harness. I suggest finding something more specific to your vehicle. This is a high dollar box I will never use now

PAC SWI-CP5 Steering Wheel Control Adapter

Mark from Mooresville, NC on 12/7/2016

2004 Acura MDX
Crutchfield Customer Review (What's this?)

Instructions were lackluster at best. Crutchfield incorrectly instructed me to use the DIP switches. To use all of the advance features, you have to use the software to program which is actually easy. But the wiring instructions are labeled wrong and the manufacture technical support person was arrogant. FYI for future installers, according to the mfg, you must either use military splice or solder, you cannot use t-connectors. Supposedly the t-connectors don't provide a sufficient connection and is causing the lack of response on some of my buttons. I haven't had the time to rip out my installation and re-do this.

Crutchfield Customer Review (What's this?)

I found the wiring configuration to be confusing and difficult to follow even after contacting a Crutchfield rep. Not all the colors lined up with what I saw both in the harness adapter and in the car. Added to this was the overall challenge of installing the stereo in my 2002 Acura TL. I've installed quite a few car stereos in the past but this one, and I believe it is more the car than anything else, challenged me the most.

I like this product it restored my factory wheel control to my Alpine X108U NAV I now can control the volume and switch songs from the steering wheel while still keeping my eyes on the road.

Pros: Adds safety to driving while listening to the radio, able to keep factory settings with after makes stereo

Cons: None

This product worked, after a little wiring help from Tech Support. As the product is made for all vehicles, it does not come with wiring specific information for your car. The product manufacturer's website has little to no info. But a call to Crutchfield tech support they were able to find the info.

No idea if this works or not. There were no wiring instructions included!


Cons: No wiring diagram! No idea how to connect this to the car

Crutchfield response on 7/26/2016 To help save on costs and protect the environment, many products don't include an owner's manual in the box. Manufacturers either include it on a disc or send you to their website to download it. However, one of our tech support Advisors, Josh, takes the time to scan the manuals for products we carry, so you can access them right from our web site. The first item appearing in the "What's in the box?" section for a product on our site is a link to the owner's manual. You can view it in your browser or download it to your computer.

Have not yet got product to work in the car. Programming seemed to be simple, I don't know for sure as it doesn't work. Wire colors do not match the instructions provided. Talke thru it with the Crutchfield team, but still not seeing any feedback from the steering wheel controls. I'm currently just using the stereo remote.

Pros: Easy programming

Cons: Not working

I tried wiring this product but the instructions were not very clear. I wired it up the way that the instructions told me to, but it does not work, I'll just have to do some tinkering to try and solve the problem. I am sure that it works great but to install it is confusing

A little tricky, but worth it

Youssef from Portland, OR on 4/24/2016

2000 Buick Park Avenue
Crutchfield Customer Review (What's this?)

I was going to dock one star because of the mess wiring this thing, but having FULL control over my steering wheel controls, even being able to reprogram some buttons I didnt use into more useful features, this is a five star product! BEWARE: wiring the CP5 took a phone call to crutchfield to resolve, and I made some silly errors on my part(based on instructions on the paper provided) Basically on my vehicle, there were some wires on the FACTORY/VEHICLE side of the harness that needed to be cut and connected directly, and that part wasnt obvious nor clear until I made that phone call. The crutchfield technician on the phone was GREAT! As I rewired the CP5 correctly based on his instructions, a twenty minute phone call later, I had a fully functioning product! He was very patient as he explained and confirmed numerous times which wires I needed, and helped me all the way through getting this thing working! I left the USB programming cable sticking out of the dash(in a non obvious location), in case I want to remap buttons, or change the way some buttons on the steering wheel work. Its a nifty little device, and if you can get past wiring it yourself, or having someone install it for you, I think its worth it

Pros: Able to reprogram buttons on the steering wheel that were barely used to do more useful stuff(Scan button now answers incoming calls) Able to program single buttons to do two different actions based on the amount of time a button is pressed(pressed vs held actions) Can easily reprogram the device with supplied usb cable, as long as that USB cable is somewhere accessible(either hidden or sticking out)

Cons: Wiring can be a bit frustrating for the inexperienced

Does what it's supposed to do

John B from cocoa, FL on 3/27/2016

2003 Buick Century
Crutchfield Customer Review (What's this?)

It does what it's designed to do, no worries. Neither the provided manual nor the free app correctly identified how to tie the unit harness into the main wiring harness, but a quick call to the manufacturer resolved it. Easy enough to install.

Pros: No complaints on function!!

Cons: My only disappointment was having to contact the manufacturer on wiring instructions. The paperwork or the app should have clearer instructions, it would be easy enough to provide. If you buy this unit, be prepared to make the call, and do so during weekday business hours. Weekend warriors like me have to pull the dash apart twice...

PAC SWI-CP5 Steering Wheel Control Adapter

Keith from Old Bridge, NJ on 3/17/2016

2001 Dodge Durango
Crutchfield Customer Review (What's this?)

It works just like the factory controls in my Dodge and I like that you can program it with the mobile app to customize the button functions to your liking. Some of the wiring instructions on the app are wrong but I called Crutchfield and had it fixed in a few minutes.There are about 20 wires on it so it might look confusing but they're all for different vehicles. I only ended up needing 5 wires.

Pros: Great if you love your factory controls and don't want to give them up. It is pretty easy to install. You can program the buttons.

Cons: Just as an FYI, if it ends up telling you in the instructions to connect both the red wire and red/white wire to the same power wire it will backfeed and the head unit and this adaptor wont turn off. Use only the red wire if this happens.

Crutchfield Customer Review (What's this?)

Unit was DOA, seems to be a common issue

Pros: Android was actually helpful

Cons: Confusing at first until you realize you only need about 2-3 of the 30 wires that come with it. Would not power on.

Crutchfield response on 3/15/2016 Whenever you encounter a problem with anything you purchase from Crutchfield, especially a situation like this, please contact our customer service or tech support teams right away. In this case we would've sent out a replacement free of charge. We forwarded this review to our Technical Support team for follow-up. Lifetime tech support comes with every Crutchfield purchase.

Great product.

Very easy install and setup. Definitely recommend.


Cons: None

Works as intended (with a few drinks)

Colton from freeport, IL on 3/5/2016

Very very difficult install, however once installed correctly it works great. I'm not docking this review because of my lack of wiring experience. This unit works very well, it's just a pain to install. Using a 2004 Cadillac CTS works great with my Pioneer X2800

Pros: Works, even with my rotary know and all buttons. Very reliable once installed correctly.

Cons: Software is a pain to program the unit. Very difficult to install and get the wires correct.

Good history, bad experience

ChrisM from Kearney, ne on 1/16/2016

2006 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

I have had pax products on the past and have been very impressed with the results I have had. So when it came time to look for a steering wheel control adapter, PAC was the first name I thought of. Even after discussing the application I was to use it in with a member of the Crutchfield tech team, it reassured my choice in staying with the pac product. After receiving and having multiple attempts to install and program, I found that this product was a piece of junk. Very dissapointed with the install instructions, especially when it came down to having the app downloaded on a mobile device to do so. After 2 call in to the tech team to troubleshoot programming issues, it still did not respond with my alpine head unit and I ended up removing it and sending it back to Crutchfield. As of now I am still awaiting a refund. I did not want to try a replacement unit, as I figured if one was junk, they probably all are. I will definitely consider a different brand next time I consider an electronic adapter.

2004 Lexus RX330
Crutchfield Customer Review (What's this?)

Went to web sight to get wiring information. A connector for the C2 would of been nice so the factory wiring does not have to be cut.

Pros: Works great

Cons: Getting it wired up was a bit difficult.


Trent from Utah on 12/23/2015

Crutchfield Customer Review (What's this?)

I had problems connecting this to my LeSabre. However after contacting the support at PAC I will always buy from them. They helped me step by step to install this product into my car. After which all my controls worked perfectly.

Pros: *Great customer support *Works as intended

Cons: *All diagrams are for connecting to the cars wiring harness not the adapter you get from crutchfield. (This really isnt a con as much as it is an FYI)


RI from Anchorage, AK on 12/17/2015

2006 Acura MDX
Crutchfield Customer Review (What's this?)

Works as intended after wiring as per PAC tech support instructions. Crutchfield support didn't quite understand my problem with this unit but did help with other parts of my installation.

Pros: Steering controls work as promised. Unit attaches near radio with Velcro tape and is out of the way.

Cons: none

Very dissatisfied

Rico from Louisville, KY on 11/27/2015

2000 Acura 3.2TL
Crutchfield Customer Review (What's this?)

2000 Acura 3.2TL. Mitgrad's review is spot on. Appears he actually got it to work. After all of the same frustration he encountered, mine physically broke. The USB port fell back into itself. Crutchfield took it back no problem. I really wanted it to work, and am pretty good with stuff, but I found this product to be substandard.

Pros: Can't think of anything.

Cons: Just about everything. A total failure.

Smart adapter

JohnC from Virginia on 11/23/2015

2006 Jeep Grand Cherokee
Crutchfield Customer Review (What's this?)

This intelligent adapter is easy to program and reasonably easy to wire. Hook it up to your computer and the PAC app will quickly program it for your make/model/year car. It's best to wire it along with your new radio since some connections are common to both and it will save time.

Pros: Easy to program Wiring reasonable

Cons: Lots of wire on the PAC plug - intimidating - but I only needed to use a few per instructions

Very good device, takes a bit of work

LiamD from Ohio on 11/22/2015

2001 Acura 3.2TL
Crutchfield Customer Review (What's this?)

This was a great choice a feel for my installation, it took a bit of work to get working but it was worth it to keep my wheel controls. The documentation for installation is not very good and was a bit confusing.

Pros: -Works flawlessly

Cons: -Documentation sucks

It works, but you will pay for it with your sanity

Mitgrad from Texas on 11/14/2015

2004 Lexus RX330
Crutchfield Customer Review (What's this?)

I can't believe that Crutchfield actually sells and promotes this device. It's not that this device doesn't ultimately work...because it does. It's the Abysmal install documentation, and the super-buggy configuration app that will push you to the edge of your sanity. To begin with, the installation documentation on this company's website is nearly absent. Nearly every reference to the installation/wiring diagrams tells you to run their app. BUT...the app will only work (and by that, I mean it won't just immediately crash on you) unless the device is attached. I found this true on both iOS and Windows platforms. And, even with the device attached, I found their app to be highly reliable. Once I finally managed to find the right delicate combination of things to make the app work long enough to spit out the wiring diagrams, I was able to get a REALLY *&!$@ing confusing set of wiring instructions. Even with two (fairly worthless) calls to Crutchfield's tech support, it still took a couple hours to figure out how I was really supposed to connect it to my car. Shame on you, Crutchfield, for selling such a horrible product, and for putting it your bundle of recommended installation parts!

Pros: After wading through Horrible documentation, and dealing with a super-buggy configuration app, the thing actually works. That's the only reason that I'm giving this product any stars at all.

Cons: Some of the worst user/installation documentation that I've ever encountered. As of this writing, their configuration app crashes/hangs on both iOS and Windows platforms unless you have the device connected. Even when the device is connected, the app is completely unreliable.

ChrisM from Colorado on 10/2/2015

2003 Acura 3.2TL
Crutchfield Customer Review (What's this?)

This is a great easy to install unit that makes your factory controls on the steering wheel work like a charm.

Pros: Easy to use, easy to install

Cons: Not all the instructions were great. I had to call customer service to walk me through some of the wiring. Of course the (should be award winning) customer service was amazing at walking me through a mystery wire.

Does what it says

Ryan from North Carolina on 9/28/2015

2003 BMW 3 Series
Crutchfield Customer Review (What's this?)

This unit does what it says, but it definitely isn't an easy install. It isn't difficult, but the documentation is poor at best and the resources online to get it done are lacking. Luckily, Crutchfield support fills in that gap. One of those stars is because of them.

Pros: It works

Cons: difficult to install. Poor documentation

Can Program Additional Controls

Dane H from Kansas on 9/11/2015

2002 Chevrolet Camaro
Crutchfield Customer Review (What's this?)

The PAC SWI-CP5 works great. I love the fact you can keep you factory controls with aftermarket radios. The ability to program additional commands to the existing steering wheel control buttons is a big plus as I can now answer & end phone calls with the buttons that I want. My 2002 Camaro SS did not come with Bluetooth from the factory & this makes using my phone easy. Installation can be confusing as you definitely need to reference their website or use their ControlPro app as you may have MANY unused/unneeded wires as I did. The general wiring instructions that are included in the box is very generic as the needed wire connections depends on not only your vehicle, but also on the brand of head unit you are installing. When you are installing it, make sure you wire the 12V ignition source in a series circuit and NOT a parallel circuit. You should separately connect the solid RED wire from the PAC SWI-CP5 to the solid RED wire on the WIRING HARNESS ADAPTER for your vehicle & THEN connect the RED/WHITE wire from the PAC SWI-CP5 to the solid RED wire on your AFTERMARKET HEAD UNIT. DON'T wire all the wires together as it will create a "power" loop & the head unit will then NOT TURN OFF when you turn your vehicle off. Programming the PAC SWI-CP5 was a breeze with the ControlPro app on my android phone. Once again, being able to program additional controls to the buttons is awesome, especially for a vehicle that did not have Bluetooth from the factory.

Pros: Retains ALL factory steering wheel controls PLUS the ability to program additional controls to the existing buttons. Programming was simple with the ControlPro app.

Cons: May have numerous unused/unneeded wires to tuck away in the dash & wiring instructions were not 100% clear.

Crutchfield Customer Review (What's this?)

The wiring instructions were poor and even incorrect but the Crutchfield tech support was awesome. Programming the unit was super easy with the phone app and it works great. Seems a little pricey for what it does though.

Pros: Does what is supposed to do

Cons: Poor wiring diagram and instructions and pricey

Had to Return it

Whitetiger from WY on 8/13/2015

2004 Buick Regal
Crutchfield Customer Review (What's this?)

I had to return this item because I could not get it to work on the 2004 Buick Regal. I emailed the company 6 times and talked to Crutchfield 3 times before it was decided that I needed a different interface. I think it would have worked IF the wiring instructions from PAC was correct for this car. Crutchfield even had the wrong wiring diagram and manufacturers connection for this car. I was not impressed with PAC Customer service . They were very vague on helping me. They would not give me answers to my questions or offer more help. Crutchfield was wonderful in trying to help me the best they could having incorrect information too.

Pros: It had features that I wanted to adapt to my bluetooth phone.

Cons: Need a proper the wiring diagram for a 2004 Buick Regal.

Kind of Works

Garey from Texas on 8/10/2015

2014 Chevrolet Spark
Crutchfield Customer Review (What's this?)

I found this hard to program. I had to reset it and reprogram it several times. Not all functions on my steering column work with this unit but the important ones do. So, I do not think it is great but it is not bad either.

Pros: Somewhat easy to install.

Cons: Lots of wires. Does not functionally work with all steering column buttons. Had to use a cable tie to hold plug in to stay in. Reprogrammed it several times by both iPhone and Computer.

It does what it's supposed to

GBTheater from Washington on 8/6/2015

2011 Chevrolet Traverse
Crutchfield Customer Review (What's this?)

Well, it does do what it is supposed to in my 2011 Chevy Traverse. All of my steering wheel controls work as they are designed to with the stereo.

Pros: Easy to program with an iPhone. Works as designed. All of my steering wheel controls work.

Cons: Challenging to wire. Certainly not Plug and Play. One more bulky thing to cram behind the stereo, wish it was smaller.

PAC SWI-CP5 Steering Wheel Control Adapter

Chad S from Pittsburgh, Pennsylvania on 7/1/2015

It took me a while to get to work when I originally installed it & then I had to get some work done at a local stereo shop & it stopped working all together. The tech contacted PAC & he couldn't get it to work even with their help. I tried to reprogram it again myself, but I could never get the app to work to program it, so i had to do it manually. The green light blinks when I hit the buttons on my steering wheel, however nothing works. The only time the volume works is when I hit the programmed stations button down & hold it. At that point the volume goes up (not exactly how I want it to work). To me this is a piece of garbage & I wouldn't advise buying it. Save your money, because it probably won't work anyway. I'm very disappointed with this purchase!

Pros: It lights up when you hook it up.

Cons: It doesn't work & the app that is supposed to help you program it doesn't work either. This product is garbage & not worth the money!

LarryB from Amarillo, Texas on 3/26/2015

2005 Chevrolet Cobalt
Crutchfield Customer Review (What's this?)

I can't say that it is a bad product... it may work very nicely in other vehicles. Unfortunately it was not compatible with my 2005 Chevy Cobalt. That vintage of Cobalt doesn't put a switched control voltage on the line to tell the CP5 unit to turn on. Therefore, it never recognizes the steering wheel control signals. The folks at Crutchfield were very helpful in advising me on installation and testing and then were most gracious to allow me to return the item for refund when we discovered the problem. The installation instructions that accompany the product were not easy to follow.

Pros: Unknown - since it was not compatible with my vehicle.

Cons: Inadequate installation instructions. I was able to figure out how to install it, but when it didn't work due to incompatibility with my vehicle, the instructions were not adequate to help me determine the problem.

Crutchfield response on 3/31/2015 Thank you for taking the time to submit a review and, more importantly, for your patience in troubleshooting the problem. Oddly, PAC's site says that the CP5 is compatible with your car. We'll investigate further and update our database accordingly.

To many different sets of instructions.. paper instructions .. mobil ap car specific head unit specific instructions.. that have a diagram at the top and then say something completely dif at the bottom... wire diagram also didn't match my new jvc unit.. so it didn't work.. $89 down the drain... good luck if you buy it expect to call support.

Pros: looked to be well made very versitile in the videos.

Cons: Poor poor poor instructions...

Not happy

Pros: Never got it to work. I've hooked up count less radios. cant say theirs a pro

Cons: The instructions in the papers it comes with an the instructions in the app will confuse you. I ended up burning out the unit cause it says hook up yellow blue wire an the paper instructions say only certain models but I entered my radio an car info in the app said used blue yellow ,an the unit started smoking. I threw it out wasted a 100 bucks

Crutchfield response on 12/3/2014 Installing a steering wheel audio control adapter can be tricky, and we always recommend contacting our Tech Support Team before you begin. They can confirm which wires are used and where they should be connected in your car. Crutchfield Tech Support is free with every order.

confusing to install, but worked

The instructions from Crutchfield were confusing. Took three calls in to tech support to get the wiring correct. If you get this it works great if you use the app to get the wiring and use it to program.

Steering Wheel Control Interface: The PAC SWI-CP5 interface allows the retention of steering wheel controls (SWC), rear seat controls (RSC), and retained accessory power (RAP) when replacing the factory radio in select vehicles. The SWI-CP5 works in a wide range of vehicles and eliminates the need for in-line resistors and massive rewiring. It can be auto-programmed for your vehicle simply by using PAC's ControlPRO app on your Apple iOS/Android device or through your Windows 7 computer; it can also be programmed manually.

Vehicle Compatibility: The PAC SWI-CP5 steering wheel control interface is compatible in vehicles equipped with CAN Bus, GMLAN, Class II, LIN Bus, I-Bus, and Analog or Serial Data SWC. Compatible vehicle makes include Acura, Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Honda, Hummer, Hyundai, Infiniti, Isuzu, Jeep, Kia, Lexus, Lincoln, Mazda, Mercedes, Mercury, Mini, Mitsubishi, Nissan, Oldsmobile, Pontiac, Scion, Subaru, Suzuki, Toyota, Volkswagen, and Volvo. Click here for complete list of compatible vehicles.

Note: The PAC SWI-CP5 is equipped with a manual learning function for compatibility with unlisted analog vehicles.

Programming: The PAC SWI-CP5 steering wheel control interface is configurable using either App, Manual, or Flash mode.

  • App Mode: In App Mode, the SWI-CP2 is easily configurable using either a Windows PC, Apple iOS device, or an Android smartphone/tablet using the SWC module's USB port and PAC's simple downloadable app. Simply download the ControlPRO application (from Apple's App Store, GooglePlay, or Windows) onto your Apple iOS 7.0+ device, Android 4.0.3+ tablet/smartphone, or Windows 7 computer/laptop. Once the app is installed, plug your Apple, Android, or Windows device into the SWI-CP2's USB port and the ControlPRO app will provide the ability to custom configure the SWI-CP2 interface and your vehicle's original steering wheel controls, to operate the functions of your new aftermarket radio. Click here for tutorial.
  • Manual Mode: In Manual Mode, the SWI-CP5 uses a pre-determined dipswitch configuration to assign the vehicle and SWC button functionality. The dipswitches on the side of the interface must be manually set to the proper configuration by the user. This mode is only compatible in vehicles with both analog SWC and a discrete 12-volt Accessory wire; vehicles with CAN-Bus cannot be manually programmed.
  • Flash Mode: In this mode, the SWI-CP5 can be configured using a USB flash drive and the supplied USB adapter. Simply download your configured vehicle file from the ControlPRO application on your Windows 7 computer or laptop to a USB thumbdrive and plug it into the SWC interface for auto-programming. The dipswitches on the side of the interface must all be set to down which is the default position. When using this method, it is not required to manually program the SWC buttons.
Note: All ControlPRO applications are dynamically updated and include the latest installation documents, control schematics, and product information for your vehicle.

Two-Function Assignment: Use of this interface allows you to program two radio functions to each SWC button by using short press/long press dual command functionality.

Programming Feedback: The SWI-CP5 interface offers audible feedback for programming confirmation and a highly visible tricolor LED keeps you informed of the SWC module's status.

  • The red LED on the interface will turn on and the +12V accessory output wire will turn on. The green LED will flash each time it sees a steering wheel button pressed.
  • In vehicles equipped with retained accessory power (RAP) the accessory output and the red LED will remain active & keep the radio on for 10 minutes unless the driver side door is opened. In vehicles that do not support RAP the LED and accessory output will shut off when the key is switched or removed from the ignition.

Memory Retention: The PAC SWI-CP5 steering wheel interface retains memory even if power is lost.

Crutchfield asked  
Why did you buy this?

Wow! This thing is pretty complicated to install, especially if you dont have the room for it behind the head unit.
