Our take on the PAC RP4-FD11 Factory Integration Adapter

by Jon Paulette

PAC RP4-FD11

PAC's RP4-FD11 radio replacement interface lets you replace the factory radio in select 2005-up Ford, Lincoln, Mazda, and Mercury vehicles. You'll still retain your factory steering wheel audio controls, rear seat entertainment (RSE) system, retained accessory power (RAP), and the use of your Ford factory amplifier, if present.

The RP4-FD11 interface eliminates the need for the steering wheel audio control adapter that's usually required for a Ford-built vehicle, saving you some more cash. Warranty: 1 year.

Important Note: You'll lose your fader control if you have an amplified system in your vehicle. The RP4-FD11 adapter does not work with your SYNC system; you'll need PAC's MS-FRD1 adapter to maintain that functionality. 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.

Features

Overview: The RadioPro4 (RP4-FD11) 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-FD11 interface allows the replacement of a factory radio in select Ford/Lincoln/Mercury vehicles with the CAN-bus system. Using this interface will retain factory features such as steering wheel controls (SWC), rear seat entertainment (RSE), rear seat control (RSC) and, the factory audio amplifier whenever the original radio is removed. The RP4-FD11 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.

Note: If the vehicle is equipped with the Sony factory stereo system, adjust the fader to your preferred front/rear setting before the factory radio is removed. Neither the aftermarket radio nor the RP4-FD11 interface has the ability to adjust the factory amplifier's fader. The RadioPro4 (RP4-FD11) does not retain your vehicle's factory SYNC system. SYNC retention requires the PAC MS-FRD1 radio replacement interface (541MSFRD1, sold separately).

Vehicle Compatibility: The RadioPro4 (RP4-FD11) is compatible with select 2005-up Ford, Lincoln, Mercury vehicles with MSCAN databus radios. Compatible vehicles as of 7/13/2012 include:

Works Great!

Written By Brian, Kennett Square, PA on Saturday, April 26, 2014
Crutchfield Customer Review (What's this?)
 
It was easy to hookup and my steering wheel controls work exactly as they should. I used it in a 2007 Ford Fusion with 6 speakers.

A couple of the descriptions of the wires didn't match up exactly but you can figure I out, based on their functions. The wires were long enough for the hookups, but a little more length on them would have made stuffing the unit in the dashboard a little easier.

It also gives you the ability to program different functions into your steering wheel buttons, but I have not true That yet.

Overall, it is a very good product. I would not have installed an aftermarket radio without it.
Pros:
Easy to use, keeps steering wheel controls
Cons:
Wires could be a little longer

Adapter rocks!

Written By FHG, Dublin, Oh on Tuesday, April 22, 2014
Crutchfield Customer Review (What's this?)
 
This adapter was perfect for my installation of the new Kenwood head unit. I was concerned that its bulk would not fit in the dash cavity behind the new audio unit, but there was absolutely no problem!
Pros:
Ease of "plug-and play" installation.
Cons:
Directions were somewhat vague in regards to the adaptation of the steering wheel controls. We had to abandon using them as a result. Otherwise, a five star rating would have been easily earned.

It works

Written By GL, Boston, MA on Sunday, March 09, 2014
Crutchfield Customer Review (What's this?)
 
It works ok, but as mentioned in other reviews for this unit in a Ford Fusion the stock console will only show DVD not the clock. Also each steering wheel control press registers on the console and stays there until another steering wheel control is pressed or the car is shut off. I think it should blank out the last command after some 5 or 10 seconds. I talked to PAC and they cannot fix this with a firmware update.
Pros:
steering wheel controls are retained
Cons:
The output to the stock console should be better.

Works as advertised

Written By Riccarr, Portland, OR. on Thursday, January 16, 2014
Crutchfield Customer Review (What's this?)
 
This adapter works as designed and my steering wheel controls properly operate my aftermarket stereo. There is an annoying side effect on my 2010 Ford Fusion. My Fusion SE has a small LED screen display which showed the clock, and previously the radio station. Now the screen will not show the clock anymore, and it permanently displays "DVD" in the upper left corner.
Pros:
Wiring and instructions are accurate and straight forward.
Cons:
My Ford Fusion SE screen no longer shows the clock.

Double-press doesn't work on 2012 Focus

Written By Chris A., Alexandria, VA on Thursday, September 19, 2013
Crutchfield Customer Review (What's this?)
 
Programming this guy in a 2012 Ford Focus (without Sync) gave me a headache, but eventually I figured it out. The real trouble was that apparently the double-press functionality for the SWC that they say you can program in simply didn't work. After resetting to default, I was able to alter the single-press, and change my "source" button to a "phone" function that gave me hands-free calling with a JVC AV61BT. Other than the initial fuss, couldn't be happier with the result. Would be nice if the wiring was a bit longer to allow the programming unit to hang further in your dash so it was accessible by popping the armrest assembly vice taking out the head-unit bezel.
Pros:
Gives a lot of flexibility for steering wheel control
Cons:
Double-press functionality doesn't work on all models.

Crutchfield Customer Review (What's this?)
 
This unit did everything it said it would. Was super easy to install and has even more options than I used. I would definitely recommend this product. This is also after I was told many times that there was nothing that I could use and retain the rear seat dvd. It all works you just cant control it from the front seat but you still can play it through the sound system.
Pros:
Easy to install, works perfectly, retains factory steering wheel controls.
Cons:
None

2 questions already asked

Will this allow the upper LCD display to show the currently playing sing title information on my 2008 Escape hybrid. I see from Kelly's answer that it displays the time, and temp info but will the 2-line display on the upper screen show text/title info for currently playing track? Thanks. [ Leo  Jun 10, 2014 ]

  • My understanding is the head unit controls what is displayed, this just allows you to use the steering wheel controls to work with the aftermarket head unit/ stereo. [ JAMES   Jun 10, 2014 ]
Hi ... did you install the PAC RP4-FD11 in a 2010 Ford Fusion? I recently installed mine that I got from CrutchField. It works well and all SWC functions are fine. What I have question about is if your LED screen (my car is SE model) shows the clock anymore? I lost the clock display functionality, plus it always shows "DVD" in upper corner. Just wondering if this is typical behavior with other people. Thanks. [ Eric  Jan 16, 2014 ]

  • Actually I ended up returning mine. In the end I could not justify the money and the cuts to the wireing harness for the stearing wheel controls. I can reach the stereo as easily as I can reach the steering wheel controls. I would not expect that to be normal behavior, since my understanding was that this would make your steering wheel controls work like a remote. Not that it would come in as a seperate line-in. This might be worth asking Crutchfield or anyone else running your stereo. On a side note, did you make the same mistake on the wiring so that your stereo does not dim with the interior lights? Ford uses a different wire than the harness shows. I need to go back in and make the change, but waiting until a nice warm day and that I feel up for it. Good Luck [ JAMES   Jan 17, 2014 ]
  • I was sent this question, but I'm sorry I can't offer any assistance. Mine was in an explorer that didn't have the screen. Put in your car, go to stereos, and click in the top bar. It has "important info" about you particular car. Should describe if that screen will or will not work with an aftermarket radio [ JASON R   Jan 17, 2014 ]
  • I did have my head unit installed by a local shop this time. My 2012 Escape Limited has the LED screen on the upper center dash as well. Mine shows temperatures, outside temperature, direction and it reads "Audio" and in upper left it reads "DVD" [ KELLY   Jan 17, 2014 ]
  • I do not have the car anymore but if I remember right, it did knock out the clock function like you say. [ EVAN   Jan 17, 2014 ]
  • I have a 2007 ford explorer, have no problem......maybe wiring? [ ERIC   Jan 17, 2014 ]
  • I did some research prior to the install and found that some features stop working intermittently and that the clock feature from the screen does not work. I decided to not use install it because of the integration it requires. Since then I have sold the fusion and bought a new vehicle. Sorry I could be of more help with your issue. You could always try contacting a reputable car audio store. They should be able to help you without any fees. [ NICHOLAS J   Jan 17, 2014 ]
