Our take on the PAC RP4-CH11 Factory Integration Adapter

by Jon Paulette

PAC's RP4-CH11 radio replacement interface lets you replace the factory radio in select 2004-up Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles. You'll retain your factory steering wheel audio controls, your vehicle's entertainment system, and the use of your factory amplifier, if present.

Another plus — the RP4-CH11 adapter eliminates the need for the secondary steering wheel control interface (SWI-CAN or SWI-CAN2) that's usually required for these Chrysler-built vehicles, saving you some more cash. Warranty: 1 year.

Important Note: If you have a factory amp in your vehicle, you'll lose the ability to fade from front to rear when you install a new car stereo. (See Details.) See Details for a list of compatible car stereos.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Features

Overview: The RadioPro4 (RP4-CH11) is a radio replacement and SWC (steering wheel control) interface that comes pre-loaded with amplifier retention and SWC software, navigation based output signals, and firmware that retains all of the vehicle's original safety and convenience features when replacing the factory radio with an aftermarket head unit.

Functionality: The RP4-CH11 interface allows the replacement of a factory radio in select Chrysler/Dodge/Jeep vehicles with MSCAN or LSFT-CAN databus radios. Using this interface will retain factory features such as steering wheel controls (SWC), vehicle entertainment system (VES), and the factory audio amplifier whenever the original radio is removed. The RP4-CH11 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.

Note: Does not retain uConnect.

Vehicle Compatibility: The RadioPro4 (RP4-CH11) is compatible with select 2004-up Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles with the CAN-bus system. Compatible vehicles as of 7/13/2012 include:

Amplified & Non-Amplified Factory System Compatible: The RadioPro4 (RP4-CH11) is compatible with both amplified and non-amplified factory systems.

  • Vehicles without a factory amplifier: Connect the aftermarket radio's front & rear speaker wires to the vehicle connector.
  • Vehicles with a factory amplifier: The factory amplifier only accepts two channels of audio input (left/right). Connect the front outputs of the aftermarket radio to the rear inputs of the vehicle connector. This will allow navigation voice prompts and Bluetooth calls to be heard. The rear speaker outputs of the aftermarket radio are not used. Fading is not supported in this application. The factory amplifier's fading is controlled by data communication from the factory radio. Neither the aftermarket radio or the interface have the ability to control the amplifier's fader.

Wiring Connection Chart: Only one of the two provided radio harnesses will be used.

SWC Compatible: The interface comes pre-programmed for all of the vehicle's factory SWC functions and does not require programming, unless you wish to re-assign the SWC functions to different buttons. The SWC functions can be easily programmed; see control settings and functions below.  The interface retains programming even if your vehicle's battery is disconnected.

Note: The SWC harness contains a Blue/Yellow wire and a 3.5mm connector. You will only use one of the connectors, based on your type of aftermarket radio. The Blue/Yellow wire supports Kenwood, Newer JVC, OEM and Blaupunkt radios. The 3.5mm jack supports Alpine, Older JVC, Clarion, Pioneer, Sony, Valor, and Dual radios. Not compatible with Soundstream head units.

Good

Written By Kevin C, Wenatchee WA on Sunday, March 16, 2014
Crutchfield Customer Review (What's this?)
 
First one was DOA, 2nd works fine
Pros:
Fairly easy install, provides all the features you need
Cons:
First one was dead, and about 50% of the time when I start the vehicle I get a decent volume pop sound. This is caused by the radio turning on before the PAC fully initializing. So the radio is putting out a signal, and THEN your speakers kick in once the PAC begins working...kind of annoying, but it's not too bad.

Needs better instructions

Crutchfield Customer Review (What's this?)
 
Once finally installed the features are working but getting to that point was not easy. The limited instructions just don't provide enough information to allow for easy assembly and installation. i finally made it thought by carefully tracing every circuit on a wiring diagram
Pros:
Adds wanted features like steering wheel control to the radio. Outstanding technical support when needed. Courteous and patient.
Cons:
Complicated assembly of the wiring harness. Better instructions would help.

Crutchfield Customer Review (What's this?)
 
One of my biggest regrets of my life was buying the PAC rp4-ch11. Nothing but issues and my radio controls still don't work on my steering wheel. Shorts, blown fuses, returns, ect and it cost this much. Find something else to spend your money on, anything else.
Pros:
None
Cons:
Takes up a lot of space, when the fuse blows it's have to radio out to change it, first one ordered developed a short in the power wire, very expensive, never worked correctly

Crutchfield Customer Review (What's this?)
 
Quite handy with a multi function deck
Pros:
It allows me to keep the functions as they were with my stock deck. I'm glad I spent the little extra for the adapter. I would have been driving with my eyes off the road looking at the deck.
Cons:
The instructions were a bit vague, Once I saw to match the wiring colors I was set. The vagueness is the only thing that I would improve on.

Incredibly easy install!! Used with my Alpine receiver. I did all the wiring connections on each piece before I even started in my Jeep. Once the wires were done, I plugged in the steering Wheel controls and the factory plugs. All done!!

Works like it should

Written By Matt G, Loveland, CO on Monday, February 10, 2014
Crutchfield Customer Review (What's this?)
 
After just a little decoding/deciphering of the included wiring map, I got everything connected as good as I could gather, and when I hooked up the deck (Kenwood) in the Jeep, I wasn't getting a signal to "turn on" the deck when the ignition was on. After a quick call to Crutchfield, it was determined that I had guessed wrong on the ignition connection, since the Kenwood instructions didn't exactly match the PAC wiring diagram. No big deal, corrected the connection, and now my steering wheel controls work just as before.
Pros:
Allows retention of steering wheel controls as well as factory stereo connector, so I can easily reinstall the factory unit if I trade/sell the vehicle,
Cons:
Wiring diagram requires a little more experience than this novice had, but Crutchfield can help you figure it out.

Fader still worked in a 2014 Jeep Wrangler with a slight work around

Written By Akaricke, Tampa, Fl on Thursday, January 30, 2014
Crutchfield Customer Review (What's this?)
 
Worked for me, BUT I had to do some trouble shooting. I have a 2014 Jeep Wrangler Unlimited. When I first installed this adapter for my new Pioneer stereo the fader and balance was going to the wrong speakers. I called PAC and they asked me if I had the factory amplifier. I told them I was not sure and he suggested to run a tone to each speaker from the factory wiring harness. I went old school and grabbed a 9v battery and scratched the PAC harness wires to each of the corresponding speakers on the factory wiring harness. Front right, Front Left, Rear Left, Rear Right. I got a response from all but the FRONT RIGHT. He said that meant I have the factory amplifier. He then told me to take the FRONT speaker leads from my new stereo and connect them to REAR leads of the PAC harness. I would LOSE speaker fader(front to rear) of my new Pioneer AVH-X5500BHS. After hanging up with PAC I started thinking and simply connected the Pioneer front left, rear left, and rear right, leads to the corresponding PAC harness front left, rear left, and rear right. Do NOT connect the PAC front RIGHT wires. Run a speaker wire from the FRONT RIGHT of your new stereo directly to the RIGHT FRONT speaker. It was a simple fix and I have full fader front to rear and balance right to left control of my stereo.

Had to buy this harness to install a new JVC headunit in my 2011 Jeep Wrangler. Installation was straightforward except one thing I wasnt sure of. After a call to Crutchfield everything was fine. Tech support is excellent! All functions including steering wheel controls work as they should.
Pros:
Easy to understand instructions, works flawlessly.
Cons:
Price. Way to expensive for what it is. But you get it half price when you order a headunit at the same time.

This unit comes with 2 factory wire looms(you only use the one that mates up to your factory harness) and its pretty much plug and play with new Pioneer unit,did not have to splice any wires from factory harness only had to splice wires together from new unit(Pioneer) to module color coded pig tails,set module to 7 for Pioneer and away we go without the need for any programing. Works perfectly!
Pros:
Did not have to cut factory harness, no need for programing,works right out of box!

This little gem does exactly what it says it will -- I didn't even have to program it. Just match up the head unit harness wires to the wires on this unit and bamm, it's done. Plug and play. It automatically detected my car and controls and made installing a full unit about a 20 minute job.
Pros:
Ease of use
Cons:
Expensive but necessary -- still a great value when purchased from Crutchfield. Super expensive elsewhere.

Decent adaptor, worked for my vehicle

Written By Scott, Nashville, TN on Monday, August 26, 2013
Crutchfield Customer Review (What's this?)
 
This item worked as advertised, allowing me to retain the steering wheel controls in my 2013 Wrangler Unlimited Sahara. The instructions were uneccesarily vague, so took a few readings to really understand that I didn't need to program anything. Once I determined that it was simply pick the right harness and start splicing wires. It is a bit bigger than I had hoped for, about the size of a component set crossover, but was still able to fit behind the headunit in the dash cavity. It did force me to install the Alpine power pack behind the glovebox, though, as there was definitely no longer enough room behind the deck. Take your time and you will be fine.
Pros:
Allows retention of steering wheel controls without any complex programming.
Cons:
Instructions not well designed, unit is a bit bigger than I expected.

Almost perfect, needs easier method to upgrade firmware

Written By Giggity, VA on Wednesday, August 14, 2013
Crutchfield Customer Review (What's this?)
 
This unit does exactly what it says, and is worth the price to be able to keep your steering wheel controls. (Though I'd like to see some cheaper competitors in this space - microcontrollers to do this kind of thing aren't expensive) However, this unit came to me with older firmware that doesn't allow programming of short keypress and long keypress commands. And unfortunately, upgrading the firmware requires special hardware. I plan on contacting Crutchfield to see if they can help me, but the fact that this is needed is just ridiculous. They could easily put a microUSB port on this thing and provide firmware updating software that could be run from a PC. The requirement for special hardware is a completely unnecessary pain. If nothing else, PAC should ship these with the latest firmware, so customers don't have to deal with this.
Pros:
Works as intended
Cons:
Firmware updates require special hardware

Was shocked how easy this made installing a new stereo in my Jeep wrangler JK. No need to cut or splice any factory wires, just match the wires to the ones on the aftermarket stereo (match the colors except for the ones not needed) and then it's basically plug and play. Was able to retain my steering wheel controls no problem. Couldn't be happier!

Crutchfield Customer Review (What's this?)
 
Works as advertised, but instructions are a bit confusing at first. Finally figured it out on my own and got it wired up correctly with zero glitches. A bit pricey to buy for just the volume controls on the steering wheel...
Pros:
Works well once wired in. No problems with it so far (only installed for 24 hours).
Cons:
Instructions lack some detail that could've been more helpful (ie: better diagrams and better descriptions of what wire goes to what (one actually labeled red power wire as an accessory wire rated at 1A supply))

Crutchfield Customer Review (What's this?)
 
Product wired up fast and very easy. Losing steering wheel controls when the buttons are on the back of the steering wheel can be extremely annoying. Instructions were easy to read and work through. I will buy another one for my next vehicle also. Good product.
Pros:
Speed!
Cons:
none

Works as advertised. Just remember to do a reset after getting it all hooked up.
Pros:
Works perfectly
Cons:
Instructions should better highlight hooking the rear speaker output to the front speakers on the harness if you have a factory installed amplifier.

Not bad, just make sure you ask about bluetooth calls

Written By rob897, Buffalo, NY on Tuesday, April 23, 2013
Crutchfield Customer Review (What's this?)
 
Wiring diagram was easy to follow. I hooked everything up correctly. As it states it disables fading from front to rear. So if you plan on using the bluetooth to make calls, contact tech support to see if you need to wire the front speakers to the back speakers and vice versa as someone else mentioned in the reviews. Once you do that it works great!!
Pros:
Easy to install.
Cons:
Should be INSTRUCTIONS for people using Bluetooth to make calls that you may need to wire the speakers differently

Worked fine for 5 days.. After that, the steering wheel controls quit working...Made a call to Crutchfield support and they quickly sent out a replacement.. works as it should now..
Pros:
The only pro is that Crutchfield quickly sent out a replacement.. the product should have worked correctly with the first unit.
Cons:
Manufacturer, not Crutchfield, should have had better QC with this product.

I almost had a problem

Written By Will, Anderson SC on Tuesday, March 19, 2013
Crutchfield Customer Review (What's this?)
 
I had trouble with this when I got everything hooked up. Called Crutchfield support and after several attempts we decided the PAC unit might be bad. Support quickly arranged for another to be sent. While removing the installed one I noticed there was a pin bent on my factory side wiring harness. Straightened it out and it worked perfectly. Thanks to Crutchfield support for the help even though I had a vehicle issue. Now resolved this works as intended.
Pros:
Works period.

Works great with my 2005 Jeep Grand Cherokee with Boston Acoustics Sound System & Pioneer DEH-X8500BH. Took about 10 minutes to wire up. Make sure if you have a factory amplifier to follw the instuctions & wire the rear speakers to the front & vise vursa otherwise you will not hear anything when making phone calls.
Pros:
easy to install

Great Interface

Written By Will, Raleigh, NC on Monday, January 28, 2013
Crutchfield Customer Review (What's this?)
 
I used the PAC RP4-CH1 Interface with my Pioneer AVH-X1500 in my 2011 Jeep Grand Cherokee Laredo. Connecting the wires was straightforward and I've never done any type of audio install or wiring before. My factory steering wheel buttons all work as they should. I did not need to program this Interface, I simply had to turn the little dial to a certain number according to the brand of receiver. The interface itself is small and there is no problem with fitment behind my receiver.
Pros:
Simplicity of installation, Performs as it should
Cons:
Sometimes if I quickly hit the volume up/down button on my steering wheel multiple times my receiver will recognize all but one sometimes two levels of volume change. Not sure if this is because of my receiver or because of this interface

Installed double din in my 4th gen ram. This interface was very easy to hook up and gave me the 12v power lead the unit needed and also the reverse and parking brake lead. This interface was easy as pie and made for a clean headache free install. Well worth the money.
Pros:
Gives 12v, reverse, and parking brake lead. Very easy to hook up and also made the steering wheel controls work flawlessly. Made install very easy.
Cons:
Price is a little steep, but worth it.

Awesome Product

Absolutely great product. Worked flawlessly. Just wired it in, turned the dial to the number designated for my reciever brand and boom done deal. All my steering wheel controls did exactly what they did before with my factory reciever. I thought it was a little on the pricey side when I bought it, but after installation and use would definitely purchase this product again for its ease of install, no programming, and functionality.
Pros:
Overall Great product

Does just what it says, though included instructions could be clearer

Written By ChuckM, Calgary, AB on Monday, December 31, 2012
Crutchfield Customer Review (What's this?)
 
I used this to replace the bottom-of-the-line OEM CD/radio in my wife's 2011 Dodge Grand Caravan with a JVC KD-A735BT. There are two harnesses included with the RP4-CH11, and you have to remove your OEM deck to find out which one you need to use. If you have the same vehicle and the same OEM deck, then I hope I can save you a little time by telling you that I needed harness "B" -- the one with the slightly bevelled bottom corners -- rather than "A," which is strictly rectangular. For me, part of the convenience of using a wiring harness is that you don't have to remove the OEM deck until you're ready to pop in the new one; it drastically increases the Wife Acceptance Factor. Having to remove the old deck first was an annoyance I'd rather have avoided.

The included wiring instructions are a bit unclear. At first, the wiring diagram made it look like I'd still have to cut into the factory wiring to connect the new deck to the speakers. This is NOT the case, as a few moments' further reading, and a look at the product details page on Crutchfield, confirmed. I used the Posi Products wire harness connectors (you screw them together instead of crimping or soldering) to connect the deck's wires to the RP4-CH11's wires, and all the steering wheel controls Just Worked when I plugged the deck into the vehicle.

I also recommend foam tape (Hushmat Quiet tape in my case) for preventing the wiring harness from rattling. Wrapped the Posi connectors and other hard plastic bits with it.
Pros:
Does what it says on the box: preserved the steering wheel controls perfectly
Cons:
There is a tiny lag when using the steering wheel controls to e.g. adjust the volume on our aftermarket deck -- a few tenths of a second -- compared with the OEM unit. It's not a big deal (my wife doesn't even notice), but I thought it worth mentioning. In fairness, not sure if it's the deck or the RP4-CH11.

This thing does exactly what it says it's going to do..I can't ask for more. Installed in a 2012 Dodge Avenger and all the controls on the steering wheel work just like they should. If you just sit down and carefully go over all the wires this is not that bad to hook up.
Pros:
Half off with head unit purchase, worked out of the box

wasn't free..some wires could have been a bit longer but i made some extensions for that

I didn't buy this product thru crutchfield. But I thought I would write a review. I bought this product thru another company for my 2008 Dodge Grand Caravan. It states that it works on 2009 Dodge Grand Caravan and up. I installed it in my 2008 Dodge Grand Caravan, and it works like a charm. would recommend this product for anyone that has 2008 or high Dodge Grand Caravan
Pros:
Works with 2008 Dodge Grand Caravan steering wheel controls.

Must have addition to car audio system

Written By Matt H, Akron, OH on Wednesday, September 26, 2012
Crutchfield Customer Review (What's this?)
 
I paid half-price for this because I got it bundled with my head unit. It is worth it but I do not think I would buy it for full price. It does exactly what it says - allows you to retain your stock featured without the stock radio. Very easy to program and is made by PAC which makes quality products.
Pros:
Easy to program. Acts as a wiring harness so you do not need to buy one in addition to this. Can update firmware. Easy to understand directions.
Cons:
Cost. Comes with pre-sets for the most popular head unit manufacturers and even some not so popular ones. Unfortunately, the pre-set for Alpine did not work with my Alpine head unit so I had to manually program it. Kind of bulky, had to be creative to get my head unit to fit with this attached to it.
