You'll retain your factory steering wheel control functions and the use of the built-in 3.5 mm auxiliary audio jack. The interface includes wired outputs for navigation radio installation and a 12-volt accessory power lead for your new stereo. Warranty: 1 year.
Note: Most vehicles will require additional installation parts please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.
Wiring harness and module were easy to install, with the only hiccup being the parking break wire but thanks to customer support it went well and easy. the new radio housing was a perfect match for the factory dash.

Wiring harness and module were easy to install, with the only hiccup being the parking break wire but thanks to customer support it went well and easy. the new radio housing was a perfect match for the factory dash.
Pros: amazing customer support, walked me right through the install! also used u-tube install videos to speed up the install.
Cons: install instructions could be better...
Plug and play!
Steering wheel controls,works like stock. 2007 Tundra.
Decided to return the Metra unit and use this instead to simplify the SWC connections on my JBL Toyota. SWC works great, but the Metra unit had better sound. I notice new clipping at moderate volumes that has me endlessly messing with the EQ. Also, the FM signal is weaker so I suspect a voltage drop to the built-in Toyota antenna amplifier - it requires 12v and is sourced by the blue wire indicated for remote power amp turn-on. I'll be pulling the unit again and testing that voltage - if it's low I'll be bypassing the TY11 and running it straight from the red ACC line. I reached out to both techs and to the sales person to ask for their experience with these 2 problems but it's been several days and no response at all which is surprising.
Pros: All-in-one interface device
Cons: sound quality, very weak documentation, decline in FM reception
the first device didn't work so i call Crutchfield and they sent me another one. Second device work. GREAT customer service.
Everything I needed to replace my car stereo, along with easy instructions. Even a novice (me) can do it. Crutchfield rocks.
All the wiring easy to interpret. Had to call about the blue remote wire, great customer support- fast and simple answers.
It works. I noticed the steering wheel controls can be unresponsive at times. The instructions are not user friendly at all. Fortunately I found a video on YouTube that did a bit of a better job explaining how to wire the unit. Just color match the wires when you are splicing them together with your head unit's harness.
Pros: Get access to your factory steering wheel controls
Cons: can be laggy Poorly thought out instructions
Very easy installation
This wiring kit includes everything that I needed to make the install easy. Everything was made simple with easy to understand directions and quick install connectors. It saved a lot of time and money by offering all together as a kit.
Not much to say, their technicians tell you which one to get and it worked. 2009 Tacoma with steering controls and it all hooked up well. Just had to figure out the rear view camera on my own because it fed into my rear view mirror but googled it and it's an easy fix.
Product worked for what I needed. Instructions for some of the wiring like backup camera could have had more detail.
This did not connect 100% of my native controls on my 2012 Tacoma. This was not a simple plug-n-play and instructions were a bit limited. My truck's built in microphone doesn't work with this system either. The steering wheel buttons work, after some trouble shooting on my own.
This thing is state of the art and my friends at Crutchfield support helped me get it installed correctly.
Pros: Easy install and interface
Well worth it!
Its a harness and interface, it works steering controls work as expected. Lotta stuff to cram behind the dash.
Three stars because mine didn't auto program and I had great difficulty going through the steering wheel control program setup. It took numerous attempts for it to work although some of that was probably a learning curve for me. At any rate I thought I was getting a unit that was plug a play. Also, like some others have mentioned, no luck with the firmware update. Maybe Crutchfield could start updating these units before shipping to the customer. If you are buying this harness, realize it is very generic and you may have many wires and connections that are unused.
Pros: Once you get it to work it functions flawlessly.
Cons: Unit did not auto program to steering wheel controls and manual programing took several attempts. Generic harness with many unused wires and connections you are forced to deal with.
light on documentation, seems to work well, though
Easy to follow install. Everything works
Pretty Much Plug and Play. I put some tape over the dip switches as I hit them on attempt 1
Perfect harness for an easy install
Would give 5 stars, but have had trouble getting the volume controls on the steering wheel to work. 2005 Tundra.
Works exactly as intended, just find a good place to mount it (I mounted mine on the bottom on my head using) because if there too much room for it to move, it will sound like there rattling in the dash.
The interface module worked flawlessly, but took a while to figure out. I ended up not using a number of wires and connections. This would be much easier to install and reduce the jumble of wires behind the radio if it were more specific to the vehicle.
Pros: Worked flawlessly
Cons: a lot of unneeded wires and connections for my vehicle
I had problems with radio reception that, as of now, I've traced back to this unit. My 2005 4Runner / non-JBL has an antenna amp that requires 12v. The PAC Audio instructions say to wire the remote lead from the radio into two wires on the harness that goes into the RP4.2-TY11. The voltage coming out of the radio was 12v, but the voltage at the antenna lead was 9.5v, which was not enough power to the antenna lead to ensure proper reception. The only thing between the radio and the antenna lead is the PAC Audio unit and a wiring harness. As of now, I've bypassed the PAC Audio unit and have wired the antenna amp directly to the radio. Reception is fine again. There's apparently an MS-Windows application that can be used to configure the RP4.2-TY11 and update firmware, but I was unable to get it to work with the unit. Maybe that provides some added configuration that would have solved by problem. Don't know. Aside from that, the steering wheel functions work fine with this unit. No ding on Crutchfield's support for this. I only called them once early in the diagnostics process, and they helped me.
It is crazy how this interface can deal with all the different systems. It handled my Toyota JBL premium system perfectly for m;y new stereo system upgrade.
Paid for the painless pre wire. It came wired wrong and blew the fuse in the new radio, blew the truck fuse, and the steering wheel controls do not work
Cons: Faulty wiringCrutchfield response on 7/23/2018 RW contacted our Tech Support team and our rep, Nikki, sent out a new receiver. Whenever you encounter a problem with anything you purchase from Crutchfield, please contact our Tech Support team right away. Lifetime tech support comes with every Crutchfield purchase.
This service made it idiot proof and easy to install my new radio.
This interface was very easy to install and works very well with options that were required to be maintain inside vehicle
Worked as needed.
Pros: Does what it needs to.
Cons: All the extra wiring, although great if needed for various install options, makes for a confusing install.
After disassembling my 2006 Sienna stock Nav Head unit, and looking at the PAC harness that Crutchfield sent I was reluctant that the right harness was sent. Held off and called Crutchfield technical advisor after speaking to Customer service. Was informed by both that I have the correct harness, however I had a automotive mechanic and electrician come by to assist, we are certain they did not send the proper harness (no pins to the harness line up). Ending up bypassing head unit just to get rear camera working and still have steering wheel control. After days of working on this, I give up. So frustrating and disappointing as Crutchfield has always come thru in the past.
Cons:Crutchfield response on 7/2/2018 Once we saw this review, our Tech Support guru, Daniel, reached out to this customer to help him further. We'll either help him get the interface working the way it should, or help him return it for an exchange or refund.
The box itself works well, but (at least the Toyota version) they tried to cover too many configurations with the plug and play harnesses. This makes for a rat's nest of wires and extra connectors. I ended up having to cut the unused wire and connectors out of the harnesses to get enough room in the dash for the module. Also wish the signal input was RCA line level instead of speaker output.
Pros: Steering wheel control is responsive and like the custom programming options.
Cons: Need to make more specialized Toyota wiring harnesses to prevent clutter or having to spend time cutting out unused connectors.
Easy to install. Fit perfectly for my 2012 Prius.
A must have item for integrating steering wheel controls to your new radio.
Pros: Easy to install.
Cons: It looks intimidating out of the box.
Works perfect in my 2011 Toyota Tundra CrewCab. I wanted to make sure my steering wheel controls would work and all do (including the Push to Talk button activating Siri). Great stuff. I paid for Crutchfield to do all the pre-wiring and it just plugged right in and worked right out of the box.
Pros: Works great All steering wheel controls work
Worked great in my 2007 Toyota Rav4. VERY EASY !!!
World great and easy to install.
I'll start by saying this worked just fine, first time, including antenna power booster, steering wheel controls, etc. the instructions could use a lot of work though. There are so many potential harnesses and wires to connect to ensure compatibility with every Toyota that I had to reread the directions about 10 times. The basics (speakers, power, etc) are easy. But I ended up with one loose wire harness that was originally in my car, and probably three connectors both in my car and on this unit unused. Everything worked though, so I guess the instructions worked?
Straight forward great instructions not to mention great customer support from Crutchfield.
Pros: Played well with the OEM harness
Cons: extra connectors not used
easier decision is get this- made installation a breeze! Steering wheel controls worked like a charm.
The Module gets a 5 star rating, however it did not properly sense the Parking Break on my vehicle. Crutchfield's tech service had a quick resolution for me that worked first try, but if you are not handy with car audio or car electronics you would have been left very frustrated that you paid the money for the function and it did not perform properly. I still had to spend time to run to a local auto parts store to grab some extra wire to run to make the parking brake work. All other functions for my steering wheel controls and my factory JBL amplifier and JBL sound system worked perfectly, ONCE I CONNECTED THE STEERING WHEEL CONTROL WIRE that Crutchfield FORGOT TO Connect.
Pros: 95% functional
Cons: Parking Brake sensor function did not work.
This interface made all the remote options of the car operate just like the factory unit. Could not see install a unit without this in the newer model cars that are out there.
Very Good Product
It works, but I was never able to get real time fade to work, so had to lock in with app. I exchanged emails with their customer service, which was helpful, but didn't get the results I expected.
Had this pre-wired by Crutchfield with a Sony XAV-AX100 and it works great. Sony head unit has function to program the steering wheel buttons which is very nice.
Pros: smooth operation
Works good but the brake and reverse trigger wires didn't work. Had to connect them straight to the radio harness. Sounds quality could be a bit better but it integrates the JBL system nicely and steering controls are working good.
Simply put, very easy to wire up the new Pioneer head unit. I really don't have much more to say than if you can see in color you can do the wiring! Easy and saved my sooo much money doing it myself and I have the satisfaction to say and show my friends that I did a professional installation myself! Great stuff Robert
Pros: Easy to follow instructions
Cons: wish the instructions had more specific directions for the blue tooth mic install (how and where to run the mic cable.
So the other reviews of this product made me a little wary of installing it. While there are a lot of wires, it's pretty simple to install. Color code the wires out of the stereo to the appropriate wires on the interface, align the dip switches, pick the correct plug for your vehicle and your in business. I have installed stereos in my personal cars before, but this is not rocket science. It made for a quick and easy install. Anyone could install this. Took a total of about an hour from opening the box to picking my stereo light colors. Very simple to use.
Pros: Easy to use, my amp and steering wheel controls work!
Cons: It looks scary. Don't fear the octopus!
Sound quality took a huge hit.
Pros: I can use my steering wheel controls and I've retained my factory amp
Cons: Potato sound quality Distorts at about 75% volume Not as loud as it was Expensive device for lower SQ Makes me wish I had never upgraded my head unit
I am very happy I decided to keep my steering wheel controls, and this PAC RP-4 made that possible. Great buy.
Love Pac modules, easy to install and always work!
My first PAC RP4.2-TY11 was defective. Crutchfield replaced it. Ditto for the second one, at which point I returned it for a refund.
Worth every penny. Perfectly intergrated the factory steering wheel controls into the new headunit. Installation was clear and easy. Definitely a must have for a perfect install.
Pros: Easy install Factory steering control integration with zero splicing
Plug and play for a 2010 Toyota FJ Cruiser with steering wheel controls. Takes up a little room, but the FJ had plenty behind the original head unit. Directions are fairly straight forward, but I didn't need to do anything other than plug it in.
Pros: Good quality, no set up issues
Cons: Requires a little room but not bad
This module is the perfect answer to easily getting your new stereo to connect and correctly use your factory amps and all of your steering wheel controls! All in one plug and play!!
Pros: Complete connection for whatever you drive!
Cons: A little bulky, but that's what allows you to be able to connect any vehicle! No other Cons!!
required for my installation
Unit works great, but installation instructions are horrible. Several third party YouTube explanations make it easy, though.
Pros: Easy to install No programming needed
Cons: Horrible instructions
Wiring a little confusing for a novice but after some trial and error works like a charm
Pros: Works great, everything worked as advertised
Cons: Directions could be a lot clearer
Worked well on my prius- no problems wiring it up and everything worked first go
Very nice unit for keeping your steering wheel controls. I am no expert in installing, so I had to call technical support a few times with questions. Staff was very helpful and made install a breeze. Very happy
This is the second one I have purchased. The first one worked intermittently after a few weeks of use. Unfortunately, I blamed the radio I installed with it at the time and since I didn't have a spare interface to troubleshoot with I had to make a best guess. Also, having limited time available to mess with car radio installations I lived with the problem past the one year warranty period. So, I finally had some time to invest in screwing around with this again and I ordered a new radio. I installed it and had the same issues. I finally called PAC and after troubleshooting we determined that the interface was bad, but would not be covered under warranty - my fault for waiting. I replaced the PAC unit and all is well, except I have a spare head unit sitting around. In short, their tech support is great - don't hesitate to call them, but my experience with the unit is 50/50 at this point. Works great if you get a working one.
Pros: Does what it says it does.
Cons: 1 st one didn't work. Difficult to troubleshoot if you don't happen to have access to a spare. Lot's of extra wires hanging around - messy installation.
A little to many wires for me to install. I had the interface and my stereo installed by a local shop. at the interface is working great. I have all my steering wheel controls, and amp working just fine
It's doing the job but because it has connectors for many models it was very difficult to fit them all in, along with the many wire splices. There were no vehicle specific tips on where to tuck them in. That was a bit surprising because Crutchfield is famous for their instructions.
I think the product works great and has lots of options for various installation needs. The directions are not great though and require a lot of internet searches to figure out how to hook things up. I used this in a 2005 45Runner with retaining factory JBL amp and steering wheel controls and its working very well for my application.
The PAC wiring interface made wiring easy. Installed this in a 2006 Prius with a navigation unit. The factory navigation unit was glitching and causing audio issues. PAC worked with me directly and was able to overcome the factory navigation fault issue. PAC and it's products are excellent.
Works good. Covers all the options for different vehicles and stereo's. Wiring instructions are terrible, and not vehicle specific. Had to do a little guess and check
Pros: Covers many vehicles and stereo options
Cons: Instructions are terrible. Did not match vehicle
Straightforward instructions, be sure to check the gain if you are having sound fade in and out. This was better than trying to figure it all out myself and maintained the steering wheel controls.
Pros: Good instructions.
Cons: Reverse wire and parking brake wire didn't do anything on my truck.
I gave this 5 even though the first one was defective. Call Crutchfield and they immedietely sent out a new one. Install was simple and all the controls works perfect including the sub/amp!
As most other reviewers have indicated, this PAC is not easy to figure out. I installed this on my 04 Tundra crew cab (twice)! The first day, I wired everything as directed, but, there were two wires I wasn't sure if I used or not. It did not work . I got up the next morning, researching the PAC, reading the instructions and watching video. This gave me a better understanding of the wiring harnesses and I was able to get it all connected. The only problem is that the steering wheel controls aren't working, in the accessory position. I will see if it works when I have the engine running. This PAC allows a full range of control through the aftermarket JVC radio.
Pros: A great option for maintaining the factory amp
Cons: A lot of wiring harnesses
Works great with the Pioneer receiver I bought.
Pros: Works with the Pioneer receiver I bought.
Cons: Only used 2 of the 5 connectors. Don't know why. A lot to fit in dash behind receiver. But it works. Directions that came with interface were not the same as what tech support sent me through email. Tech supports made more sense.
This unit seems overwhelming at first mostly due to the poor instructions. Starting with the aftermarket stereo speaker connections gets you started, everything after that is pretty straightforward. I also purchased this under the belief that I WOULDN'T be able to retain steering wheel control (2007 Tacoma) and was pleasantly surprised to see I could. I had to make a call to a crutchfield tech to finish installation, but they were able to get me sorted out. The knowledge held at crutchfield is why I will be a repeat customer.
Pros: Retains steering wheel controls Retains factory amplifier
Cons: Pain in the neck instructions.
Thankfully I had my harness premade or this would have been brutal. I have 6 factory connectors and 4 from the SWC that are unused and had to find room to tuck them in behind the receiver. The software had to be installed twice on my laptop and the same for the firmware. Programming was really fast to perform. Had to bypass the box to get my backup camera working. However, it was exactly what I needed to minimize the effort needed to install.
Cons: Instructions are confusing for a novice. Not clear what wire does what or is needed, since there are so many.
Instructions were not that straightforward when combined with the radio (pioneer) instructions. Once I got it figured out, it was ok. Still a bit challenging though.
Work well, pretty straight forward to install
Pros: Color cordinated wires made easy to hookup
I installed this module in combination with a Pioneer AVH-291 BT in my '06 Tundra. I chose this combination with Crutchfield's recommendation to retain my SWC. The instructions are confusing, mostly because I think they are trying to cover multiple car manufacturers with one document. Once I figured it out, it was easy to install. The system worked great for about four months then the sound started to fade in and out. At first I thought it might be the deck and with Crutchfield's excellent CS I started some troubleshooting. I couldn't find any issues with the installation so they sent me a replacement deck and module. The first thing I replaced was the module. PROBLEM SOLVED! For some reason the module was causing the issue. If it happens again I might look for another alternative to this module or bypass the SWC all together, which would suck. Good luck if you purchase this product.
Pros: Retain SWC
Cons: LOTS of wires Poor instructions Malfunctioned after about four months of use.
Bought an aftermarket radio from Crutchfield a year and a half ago. The stereo died this past summer after less than a year. Really frustrated and prepared to trash the radio in a review, but wanted to make sure that it wasn't simply a fuse. Haven't had time to investigate and have been driving around with no radio since mid summer. My brother - in town for the holidays - offered to take a look at it for me today. Turns out PAC unit is the issue. Died after less than a year and had to purchase a brand new one to replace. Really, really not happy right now.
Pros: Worked...When it worked...Which wasn't long
Cons: Have to replace after less than a year. Not Happy.
Worked as expected. Can't ask for more.
Pros: - Converts the stock connections so they can be used with aftermarket decks.
Cons: - Doesn't support all stock connects. ex. stock Bluetooth mic and satellite radio antenna.
Great product. Shipping time was quick. Product received in perfect condition.
2003 4runner. Product did the job and retained steering wheel controls. Instructions are a challenge. Better instructions can be found on PAC audio website, but even those instructions contain generalized direction. Just matchup the wires according to function and don't over think it, you will have unused wires and connectors. It's a big glob of wires to stuff in the dash, I ended up taping things together trying to streamline the wiring birds-nest. No programming needed other setting the dip switches to match new head unit.
This was the easiest way I have ever done an after market install.
This works. the wiring instructions are not the best but, if you have any wiring experience you can figure it out. I would like to see more detailed instructions, but that may not be reasonable due to this unit may work on many different vehicles.
DIdn't allow me to use my answer/hangup/voice(siri) buttons on the steering wheel like my previous SWC box did. :(
Pros: Didn't require any special programming for the buttons
Cons: Not all buttons worked even after trying to program them
This wiring interface was easy to hookup to my car JVC radio so I can use the steering controls.
Easy to install
Worked perfect. I did have to call Crutchfield for some help understanding the instructions. But does what I needed
Pros: Does what it is designed to do
Cons: Instructions are a bit hard to understand. A lot to stuff in the dash
Great product!! Just plug and play!! Made my install that much easier! Only thing was a little vague on the instructions.
Made installation so much simpler. It helped my steering wheel controls to continue working.
Pros: Easy to install.
After reading some of the reviews I was a little concerned that it might be a little confusing to install. On the contrary it was relatively easy. Just be sure to read the instructions completely before you start connecting the wires. Be sure to turn up the "gain" control if not you won't be hearing anything. You'll end up with unused plugs due to the fact that it'll work on different factory connectors. A
Pros: It works!
could not have been easier, everything worked as it should,
The interface worked out of the box with no modifications/programming but the instructions are useless. There is a more updated version on their website (http://pac-audio.com). Even then the instructions are incomplete/inaccurate in some cases. If you have a 03-04 4Runner without the factory nav then you need to ignore the instructions concerning the reverse and parking break sensor wires. The instructions tell you to connect the white twisted wires to the CAN High and CAN Low pins on the OBDII port. Those don't exist because the 03-04 4Runner uses the older ISO bus OBDII system, not the newer CAN system. The parking break wire is found in the fuse panel by the drivers left knee. Look to the left of the fuses and toward the bottom of the panel, you should see two light green wires (one on top of the other). The parking break wire is the one on the bottom (pin 2). The reverse sensor wire can be found in multiple locations but the one we found the easiest was under the driver side door sill. There is a junction where the wires are exposed, if you gently move the wires around you will find a red wire with a yellow stripe. That's the one. I don't know where the vehicle speed sensor wire is since our head unit didn't require it. Overall a good unit that functions well. Would be 5-stars with better instructions.
Pros: Functions out of the box with no programming required.
Cons: Terrible instructions, download an updated version from the PAC-Audio website.
This made the installation easy after figuring out that there will be extra unused connectors.
Cons: Extra connectors to fit behind the stereo.
Installed this in my wife's Sienna with a Pioneer AVH-1330NEX. The instructions are not horrible, but I could not find the green parking brake wire that the instructions said should be there. All other connections are there. I had to run the wire separately instead. The point of getting this was so I wouldn't have to run extra wires and splice into the car's wiring. Other than that, the steering wheel controls are retained without having to program this unit. The instructions give options to use a laptop for some settings, but you need Windows. There is no option for Mac or Linux. However, connection to a laptop was not needed.
Pros: Retain steering wheel controls. No extra setup when installed.
Cons: No parking brake wire that was listed in instructions. Need Windows laptop for "extra features".
Works my steering wheel controls great. I don't have any problems using them at all. Love it, biggest fear was loosing my control functions on my steering wheel. That would've been a bummer.
Pros: It works just great ,no regrets. Great price for it too.
Cons: I don't see one here.
What it does, it does perfectly - links the controls of the radio to your steering wheel controls. What it lacks are any useful instructions as to how to achieve that. Not once in the manual is there anything like an instruction to "join part A to part B". There's a diagram of what most, but by no means all of the various sockets are, but absolutely ZERO instructions as to what to do with them or the large bundle of wires that accompanies the sockets. Luckily the Crutchfield guys on the phone are brilliant at visualizing the mess in your car and can talk you through how to make it all work, but shouldn't basic instructions be a mandatory...?
Pros: Works perfectly when finally fitted.
Cons: Instructions are as useful as a chocolate teapot.
I installed this in a 2004 Toyota Tundra with JBL audio using a Sony XAV-AX100. Worked well and seems like a big improvement on the previous interface I bought. Audio levels are much better. Lots of wires, but take your time and do your homework. I made one call about the remote control wire and it was confirmed as I expected. I soldered and heat shrinked the whole thing together and it worked perfectly the first time. Also gave me steering wheel controls which I didn't have previously. Instructions aren't great but don't be a whiner. Do a little reading, ask a question if you need to, you should get it right the first time.
Pros: Big improvement on the previous interface
Cons: Lots of wires, but hey you wanted a cool stereo
poor instructions and not vehicle specific as I thought. extra wiring/connectors not necessary only made fitting into dash that mush more difficult. also, had extra brown wire not found in wiring diagram
Pros: price with hu package
Seems to work fine. It wasn't clear to me how it should work based on the instructions provided. There seems to be a lot bulk with all of extra connections and wires, but I was somehow able to make it fit.
Installed on 2003 4Runner, pioneer avic5200. The unit worked after accidentally pressing program button while inserting box behind dash. Had to reset and all was well with steering controls. My car did not have 28 pin harness plug, and could not use odb2 direct port, had to find speed, reverse wires manually. Overall good product. They need to refine the wire structure since the length creates a dashboard challenge. Also instructions can be confusing when deciding if to connect directly to car harness vs pro radio harness.. i.e. Antenna blue amp wire needs to go direct to car harness from radio, not pro adapter. Crutchfield tech support very good, if you install radio, they are worth their weight in gold, fast response even on weekends, go Crutchfield.
Pros: Product works as expected.
Cons: Wiring harness a little challenging to fit in dashboard. Instructions could be more clear. No amp antenna hookup info.
Weak instructions as noted by others. Quite bulky bundle of wires. Hard to find a good way to fit all of it in behind the receiver unit. I'm sure this allows them to make many wiring bundles for various applications for the same unit. But the result is less than ideal. Functions as expected.
Cons: Instructions could be better. Large wiring bundle.
The interfaced worked, the new stereo works, and I can make calls from my Bluetooth phone. However, the instructions were a bit cryptic, there were two different wires of the same color that matched the wire coming from the stereo (blue w/yellow stripe), and there were several connectors coming out of the interface box that didn't connect to anything. Anytime I build something from a kit and have some pieces that look important left over, I spend a lot of time scratching my head trying to figure out what I did wrong. If the instructions had said "you may have some unused connections", I wouldn't have spent as much time thinking and would have completed the installation much quicker.
Pros: It works
Cons: Instructions are vague
Great product! I installed on a Toyota Avalon 2006. Everything is working! The head unit the steering wheel buttons and the information screen. BTW the head unit is an Android unit.
Good: wires a prestripped, making connecting them to the radio's harness that much easier. Bad: the wire identification chart is poorly organized, identifying wires that can't even be connected to
Product works well and does what it is supposed to BUT the instructions are horrible! It took 2 calls and a new unit (which wasn't needed) to get it to work properly. Operator error but basically could have been solved with better instructions.
Pros: Does what it's supposed to do
Cons: Instructions are severely lacking!
Works as advertised. However, installation manual is very poorly written, practically useless. Be ready to call Crutchfield tech support when wiring this. Few minutes with Crutchfield tech support will clear things up. The amp gain control is very finicky. I tried to increase the level a bit and the whole system turned silent. The gain dial doesn't seem to have any logical increment. The sound came back at some random position. I recommend not touching the amp gain dial.
Cons: Poor installation instructions.
The comments from others about having to do a lot of research to figure out how to hook things up were right on the money. The tech support teams at both the manufacturer and at Crutchfield were great and answered emails within a day. I hooked it up yesterday and it worked great on the first try. No problem with the steering wheel controls or any of the speaker/amp connections. The only thing I would change is the instruction sheet and taking some of the ambiguity out of the wire-to wire connections. Maybe a vehicle/feature specific wire list would be helpful as this device supports a number of different Toyota and Lexus vehicles with a number of different radio installations. Some of the wires and connectors end up being unused if they support features your vehicle doesn't have which is fine but would be great if they were more clear about that in the instructions.
Pros: Works great, leaves factory connectors/wiring intact
Cons: Unclear instruction sheet for installation
The instructions were seriously lacking. If I didn't have experience in electronics and electrical systems, I would have been lost. I found the steering wheel controls to work as advertised once I figured out how to connect them. I my case, the 3.5 mm jack connected as a remote input did the trick since my new stereo didn't have a matching blue/yellow wire. For an inexperienced installer, there would have been a lot of phone calls to figure this out. The input wires that didn't terminate into a connector should have and passed thru to the radio connector output harness so there's no ambiguity about which wires to connect.
Pros: Almost plug and play
Cons: Instructions were terrible
Excellent product for adding after market stereo/nav head to cars with OEM premium JBL sound systems. Easily integrates factory amps and controls (including steering wheel controls) to aftermarket unit. The interface is designed for several different cars and configurations, and so there are extra connectors that may not be used for every install. Sorting this out may take a few minutes as the instructions are not as detailed as I would have liked. However, the one wiring question I had was quickly solved by the Crutchfield tech support team. I would highly recommend this interface to anyone replacing a factory radio with an aftermarket head unit.
Pros: Keeps original OEM controls and functions of the car and sound system.
Cons: Installation instructions could be more detailed.
As long as aftermarket stereos require these interfaces the car audio technicians will have secure jobs. I spent many hours with online videos trying to understand how to make all the connections but became more confused . I was completely surprised when after connecting all the harnesses together that my unit actually worked!
Pros: It actually worked
Cons: Too many different ways to make errors
OK...this thing works and pretty well too BUT it was a major hassle to install. At lest 12 wire connections are required and the wire monster created behind the head unit was a pain to get into the dash. Three calls to Crutchfield to get it done - lots of wires and hook ups from the car and on this interface are NOT used and that is quite confusing for a novice installer like me. Anyway, I got through it and it worked very well. The steering wheel controls were already set and I did not alter them. given how hard it was to get all the wires in my dash I shudder to think about pulling it out to reprogram it!
Did end up being plug and play but it certainly look some time studying the instructions to realize what wiring applied to my specific install and what didn't. If I didn't have the experience and knowledge that I do, I doubt I could have achieved success based on the quality of instructions provided.
Pros: It works
This interface barely worked with my 2005 Prius (with factory navigation). The install instructions were spotty and hard to follow. The harness had THREE (!) blue-white wires, giving me many different permutations to try. The interface never controlled the factory amplifier correctly - it would routinely play for 10-20 seconds, cut out for a second, and repeat. Whenever I had it plugged in, it would either completely disable the factory navigation or cause it to randomly display audio volume and non-connected device banners. I sent one of these back after spending too many weekends installing it. Crutchfield exchanged it for another one, which had a differently-wired harness and more recent firmware, which didn't work either. We finally swapped it for a set of Metra interface boxes, which did work. I am happy with Crutchfield - not so much with this interface.
This item is going to be the downfall of my player, I can't seem to get the all the steering wheel controls to work volume up and down is all that I can get to work. The other problem is there are so many unused plugs I am going to have to extend the wires to tuck this unit away from the head unit because there are clearance issues on my Toyota.
Cons: To many unused plugs.Crutchfield response on 3/28/2017 Willie, we're sorry you're having problems with your interface. Whenever you encounter a problem with anything you purchase from Crutchfield, please contact our tech support team right away. They can help you solve the problem and get the interface working properly! Lifetime tech support comes with every Crutchfield purchase.
The wiring interface works great. I am able to use my steering wheel controls and everything is functioning perfectly. Figuring out the wiring was a little difficult as the instructions are not really clear, and some of the wire colors are a little off, but just give a Crutchfield technician a call and they will walk you through it. Finally, awesome tunes again in my 2003 4Runner.
Pros: Works perfectly; easy plug and play once you figure out the wiring.
Cons: Wiring a little difficult to understand, but nothing a quick call to the Crutchfield techs won't solve.
Works great. I was a bit confused about what went where but eventually figured it out. I think a few more instructions would be helpful. Once you've used this setup once it's probably intuitive/simple, just not the first time out.
This interface performs well and does what it's supposed to. However, for my application the installation instructions were lacking. Installed in a 2005 Solara Convertible. The instructions referenced a 28pin connector on the car side that does not exist. There are also 3 extra plugs that they do not specify may not be used in your application. The UP SIDE of all this was the Crutchfield Team. They were fantastic with the phone support; very patient and polite while going through a process of elimination to isolate the issues. In the end the unit performs well and does everything it's supposed to. Lots of cool options to tweak your Steering Wheel Controls.
Pros: Lots of cool options and tweaks allow lots of personalized settings - Basically plug and Play
Cons: Installation instructions incomplete/inaccurate for my application
Tech used this to include steering wheel control. Nice to have complete control without having to touch the radio.
This is a great product and exactly what I ordered for my Toyota Sequoia, installation was very easy and right to the point and the product came in a very quick and timely matter . The sales rep made sure that I ordered the correct product for my vehicle.
Pros: The entire project was purely plug-and-play, very simple installation process.
makes life a lot easier,
This was a disappointment. The instructions were useless. I hooked up wires, and the radio works, but not the steering wheel controls. I installed this at night, and did not call tech support. After removing all of the trim to install, I'll leave it in rather than return it to Crutchfield.
Cons:Crutchfield response on 3/8/2017 Steven, whenever you encounter a problem with anything you purchase from Crutchfield, especially a situation like this, please contact our tech support team right away. They can help you solve the problem or set up a return within 60 days of purchase. Lifetime tech support comes with every Crutchfield purchase.
Was able to keep factory steering wheel controls and JBL amplifier. Surprised to find out that the factory navigation still works on my 2007 Toyota Avalon. Instructions left much to be desired. This interface fits multiple models, so there will be extra wires to confuse you.
Did Not Work
Cons:Crutchfield response on 2/22/2017 Once we saw this review, our Tech Support team reached out to help this customer. We'll either help them get the interface working the way it should, or help them return it for an exchange or refund.
The adapter kit did the job, but the wire lengths were a bit short is a couple of places. Also, there were wires that were not covered by the documentation with Acronyms for labels. The documentation should at least tell you what the acronym means.
Pros: Did the Job
Cons: Documentation could use an update
Works perfectly,pay the extra $ and have prewiring done Makes for easy install
This harness covers a wide variety of vehicles. That being said, this was my second time ever doing an install. Had a couple of wires that I wasn't sure about but the staff at Crutchfield was amazing and helped me through all of it! Great harness especially having the ability to program certain functions on my steering wheel!
Pros: Amazing functionality
Cons: Not for beginners, Crutchfield really came through for me!
I was worried about this product based on mixed reviews. I have to say I am pleased that I got it. Pretty simple to install and works as advertised.
Pros: Works properly
Cons: Nothing really. Instructions could've been a little better but common sense is really al that's needed. One issue I had was quickly explained to me by tech support
Easy install. Didn't bother with any of the steering wheel control customizations but all of my steering wheel buttons work as expected. I was confused about the wiring harness because it is not clear that they don't all need to be hooked up. On my 2005 Sienna with JBL, only two of the harness connections hook up to the car. There is a third small black plug coming from the car that does not get hooked up to anything.
The PAC RP4.2-TY11 came up as the option on Crutchfield for a 2007 Prius with JBL to retain the steering wheel controls. If you search Prius forums for 2nd generation (2004-2009) Prius installs, you will see that there have been some issues with this unit. For me, it was the intermittent cutting in and out of the signal regardless of input. The better option is using the Axxess TYTO-01 and ASWC-1 (and ASWC Harness) to avoid the issues. Crutchfield replaced the PAC with the Axxess and everything works fine now. Again, your mileage will vary. You will still need to add a resistor to get the MFD working properly with the Axxess system.
Pros: All in one solution (but you won't use all the connectors)
Cons: Instructions difficult to follow. Has issues with 2nd Generation Prius systems.
Worked well for connecting my steering wheel controls to my pioneer head unit. Only complaint was that supposed my deck could take a voice recognition input and I programmed a button to do this but could not get it to work. Not the end of the world though. Had to call support once or twice but crutchfield support was awesome and knew what they were talking about. Really like the ability to program long press and short press to gain more features.
Was very confusing but after a couple of hours I had it figured out.
Pros: Works well on my 2012 Fj cruiser with pioneer DVD deck
Cons: Very confusing instructions,lots of extra stuff not used. Seems like it could be simplified.
It works but the instructions could be significantly improved. It would be great if Crutchfield provided additional documentation with this product.
For a seemingly simple device, I found the unit to be more complex than expected. I also found the instructions to be somewhat lacking. There is basically only a wire ID chart for wiring. I realize that there are practically an infinite different set-ups which would make traditional wiring diagrams difficult. But for my set-up, it required a call to Tech support to understand the remote/amp wires and the unused NAV wires. I had to also question the unlabeled brown wire that was unidentified (different than the brown loop). It was also concerning that one of the stock connectors was left unconnected, in the final configuration. Everything worked fine. But a note about this might be helpful. Most disappointing was the Tech support I received when trying to figure out the programming and interface to the new Blaupunkt head unit. I'm an engineer, but found the programming instructions less than concise ( calibration vs re-assigning, ect and the actual steps to program). Tech support was no help with this indicating that this unit and the Blaupunkt units rarely work together, opposing what sales told me. I did eventually get everything working properly. But it required significantly more time than expected. Better and more detailed instructions would be helpful.
Pros: Works great with the steering wheel controls
Cons: Poor instructions , poor wiring diagram and unclear programming instructions
Nicely built harness however in my particular fitment many leads and several connectors remain unused.
Worked great and easy install!
Very intimidating when you open package and review the very minimal, confusing and inadequate instructions. BUT if you lay out the wires, plugs and such; map out what you understand and what matches up, then just make a list of questions and contact Crutchfield tech people, they will answer all your questions like magic! I was dubious when I called but was blown away with their help. Installation went well and as I held my breath and powered the unit up all was well.
Pros: Allows not only use but customization of steering wheel controls.
Cons: Very poor instructions with harness.
Really complicated...took a number of calls to crutchfield tech support and the manufacturer pac to get it fully up and running. Retained a number of the steering wheel controls of my wife's Rav4 directly out of the box.
Pros: work as advertised
Cons: needlessly complicated
Was able to install and retain factory functions in our 2010 Prius.
Not a DIY type project for my 2005 Toyota Sequoia. Couldn't have installed without the excellent Crutchfield tech support. Had to call 3 times total to get it installed. Do not buy from a cheaper source because you won't get tech support. And chances are, you'll need it!
Pros: Installs into factory harness
Cons: Poor install instructions
Initial impression: The unit is overly complicated and tries to fit too many models at once. Directions a bit obtuse. Only a few of the connectors attached and hard wired were needed. The rest just take up space and clutter otherwise neat wiring. Rather confusingly, the wiring colors do NOT match the directions. Crutchfield was also initially stumped as well since PAC changed the very much needed blue with white stripe remote turn on wire locations. A call by me to PAC got not much of a response. Worse, even once sorted out it did not work. After much time and several calls to Crutchfield's tech support later we realized the unit was likely defective. Crutchfield quickly shipped a replacement, which confirmed our suspicions. While the new one worked the performance was a bit erratic. Had to re-program it, which is a bit awkward and must be performed in an exact order. "Preset" and "Track" may not be consistent from vehicle to vehicle. Took a few tries and re-sets. An easier method with a laptop apparently exists, but only works without on a Windows computer. Great, really, Nobody uses a Mac. Sigh... However, after a few tries and a deliberate reversing of up and down to match the on screen movements it finally worked. We will see how this continues over time. My time and patience are limited and this challenged both. Without Crutchfield's tech support I'd have simply returned it all.
Pros: It finally allowed steering wheel controls to work.
Cons: Overly complicated and at times less than clear directions. Possible quality control. I am not the only reviewer here to have a defective unit.
Product performed as specified. Installation instructions were not exactly correct. Had to make several calls to Tech Support. Finally after additional diagrams were sent, I was able to get everything working. I like being able to use the steering wheel button controls with the after market receiver. Gave it a 4 only due to missing data in instructions.
Excellent interface. Excellent support for Crutchfield. I tried three different interface cable clusters from sites that indicated they would support my situation, i.e., car to aftermarket radio. Everything snapped together easily and the splicing that was required was the same as any straightforward car radio instal. I had a little trouble with the steering column interface connection and an easy call to the Crutchfield support line resolved the issue quickly.
Pros: Easy install (similar to any aftermarket clip and splice).
It actually works! Yes, I installed this in a 2005 Toyota Avalon that originally came with the JBL stereo and amp. And it works perfectly. The amp works and the info screen still works for the AC and other non-stereo functions too. I had read up on installing on aftermarket stereo in an Avalon. And most installs include using a long wiring harness to put the factory stereo in the trunk in order to keep the info screen working. But with this PAC module, it's just plug and play. The stereo I installed was a JVC single DIN unit. It doesn't have the option for steering wheel controls, so I wasn't able to try that out. This is my daughter's car and I plan to get her a nicer double DIN unit for Christmas. I will then see how well the the PAC module retains those controls. But I suspect they will be fine. As others indicated in their reviews, the instruction are not really good. But in the Avalon, everything goes where you expect it to. So there was no hang-up. But I specifically bought this from Crutchfield because I wanted tech support in case I couldn't figure it out.
Pros: Works exactly as advertised in 2005 Avalon.
I installed the PAC RP4.2-TY11 in my 2004 Toyota Tundra with the JBL stereo system. It's a perfect plug and play solution for the JBL system. The stock steering wheel controls works perfectly. I've put off any stereo upgrade because of the JBL system design.
Works as described. Now I have an aftermarket stereo and have full functionality of the steering wheel controls (SWC). The only reason I'm not giving it five stars is the instructions. It labels all of the harnesses and identifies each wire, but doesn't tell you exactly what to hook together. Also know that on your vehicle, you might have a couple of harnesses that you don't even use. I didn't know that at first so I wasn't confident that I had set it up correctly even though I did.
Pros: Does what it should. If you know a little bit about car audio and already generally know what wires need to go where you'll figure it out.
Cons: Confusing instructions. If you have never done a stereo install yourself you may not be able to follow the instructions. They lack some steps and details.
Installed this in my wife's car. Works great; however, somewhat complicated to install. More so because it doesn't really state that some of the harness is not required on some installs. Had two connectors that were not used.
Pros: Works as described.
Cons: Installation directions.
Parts did not provide interface for SWC connections as advertised
Cons:Crutchfield response on 9/14/2016 In response to this review, Daniel, one of Crutchfield's Tech Support Specialists, reached out to inform this customer that this interface does include steering wheel control retention for his RAV4. Daniel assisted him in the steps to make this happen and asked for the model of his radio to help him further.
Not truly plug and play. Needed additional adapters for proper antenna hook up. Like ability to add additional programing to steering wheel control.
Awesome product it allowed me to keep my premium sound system that came from the factory which includes my steering wheel controls.
Adapter allowed me to keep factory steering wheel controls! Needed tech support to assist but was a good experience
Pros: Allowed me to keep factory controls
Cons: Lots of wires!
Working fine, some install instructions were confusing,
Pros: Does everything it is supposed to
Cons: Instructions confusing in spots.
The PAC wiring interface was everything I needed for an easy and complete installation of my new radio. It included the steering wheel interface. The instructions were a little complicated for a novice like me. However, once I got started it seemed to fall into place.
Pros: Everything was included
Cons: Instructions are not as clear as they could be
This wiring interface works great. I had very little trouble connecting it and getting it to work the first time. The instructions were a little overwhelming at first, but once I realized that my setup was relatively simple (I have the JBL speaker system, which handles all of the sound distribution), the audio connections and steering wheel controls worked the first time. The only problem i had was that my 2009 RAV4 has an antenna booster built in, and there is no connection in the PAC RP4 that connects to the antenna booster power in the car wiring harness. It took a couple of calls to Crutchfield to sort that out, but they have a note on which wire to splice into in the car wiring harness to connect to the Power Antenna radio wire. All was well after that.
Pros: Full featured, allows connection to my steering wheel controls
Cons: Instructions are a little complicated, but Crutchfield tech support easily handled my questions.
Great product a little hard to wire. Had to splice in to the reverse wire to get the back up camera operating. Couldn't have done it without the great technical support of Crutchfield!!
Pros: The hands-free controls were great stereo sounds good.
Cons: The hands-free controls were great stereo sounds good.
The instructions are not descriptive enough, You may need (most likely) a windows laptop to complete installation, after many, many calls to Pac audio and Crutchfield I was able to install it, but, there is a problem using this with Prius vehicles and only found out after consulting a few radio installation shops, the RadioPro4 is more problematic than they are worth and that most installers stick with the separate radio interface and steering control modules. I had a terrible unresolved issue with the volume on the stock amp bouncing up and down from 28 all the way up to 60 (max) and back down again, there was no resolution to the issue and I had to return it, I would suggest that if to have a second generation Prius that you do NOT use this module, it is bug ridden and most of the time result in undesirable issues. and don't bother calling Pac audio, the have no idea how to resolve the issue.
Pros: Should be an all in one solution to integrate your radio into your car's OEM digital amp and also have your steering wheel controls work.
Cons: Bugs in the unit itself are a major issue to having a successful install of your radio, they are know issues by radio installers and by Pac audio but, they have no intention of resolving them, I was told that the my Prius was an "old car" and that they cannot solve every issue that comes along with older cars.
Once I got it in and and working it is perfect but to much extra wire that are not need however is get 4 stars in my book
Pros: It works great with my aftermarket radio
Cons: To many extra wires need better install diarection
Great product easy install
Pros: Steering wheel controls work great.
Cons: Had remove radio twice because of lack of space behind radio I hit the program buttons disabling the controls
fit two of my four connections , seems to work well so far.
Pros: good instructions
Cons: lot of extra connectors.
Bulky and all of the extra untiltled wires make this unit very frustrating to install . I don't like having incomplete instructions but i finally made it through after taking the head unit harness and interface harness to a local shop that happens to have one of the Top one hundred installers in the nation ( he has the awards to prove it ) .
Pros: It works.
Cons: Lacking of a complete schematic.
This install kit allows for an easy install for the novice. All you may need in addition are butt connectors and a crimp tool. If you read the directions carefully all goes perfectly.
Pros: Plug and play for the most part, good directions
Used as a replacement to the Metra Axxcess which wouldn't work for me. The RP4.2 installed easily and worked flawlessly.
Pros: Everything all in one unit, Good website and installation instructions.
Cons: Needs more labels for wiring harnesses.
The Toyota Avalon has a lot of electronic bits and pieces, and I thought I'd have to give up a bunch of them in order to install an aftermarket head unit. But this harness saved the day, and I was able to retain everything I used (you lose the stock nav, but I never use it). The instructions are straightforward, and the wires were all color coded and labeled as needed. Overall, this harness solved my problems and was easy to install.
Pros: Retains majority of core features, good instructions, easy to install.
Not a whole lot of documentation so I had to do some guesswork. Fortunately, wires are color coded.
Pros: It works
Cons: Lack of documentation My brand wasn't listed under programming...has to manually program the steering wheel buttons
Troubleshooters, look here. I had purchased a "new to me" 4runner, and immediately ordered a new stereo (CDE-153BT) to put in it, and sprung for the extra cost of this harness to handle the factory amp and steering wheel controls. This was probably one of the more challenging installs I've done, as it's a LOT of wire, and trying to find a spot to cram it all in was a bit of a challenge, but it eventually worked out. After about a week, I started having intermittent issues if I was listening to bluetooth music and would receive rapid-succession text messages. The sound from the radio would completely cut out, even though I could tell sound was still playing. Convinced it was a faulty stereo/BT, I exchanged the CDE-153BT for a CDE-HD148BT, and am having the same issues. At this point, I'm now convinced that it's not the head unit, but this adapter that is causing the issues, and am getting it replaced, once it comes back in stock. Ultimately, I need the functionality so there's not much of a choice here, I just wish it worked better.
System features and appearance is what I was looking for, but the only complaint I have is the display. During daylight the screen cannot be seen when navigation to either the XM portion or to the tuner, cannot see anything unless it's night time!
The adaptor worked flawlessly when first installed which was a very pleasant surprise to me, so i was very happy. However that was short lived with in 3 days it would not work at all. Crutchfield is sending a new unit. However I'm out the time to reinstall the unit.
Pros: Worked out of the box
Cons: stopped working with in 3 days! Installation instructions are poor at best wire harness should be more vehicle specific for custom fit!
Trying to figure out the wiring for my '07 Camry with the JBL system would've been impossible without this thing. If you're familiar with connecting wiring harnesses, it shouldn't be any problem installing it. . . .
Pros: Easy to install once you know what you're doing. Not ridiculously expensive, but not cheap.
Cons: The unit is a little big. The sticker/tags on the wires are slightly misleading. I had to connect wires from each end in order to accurately connect my new receiver, but only wires on one end of the unit were labeled as "to new receiver." The directions were sufficient enough to get it installed but were very much lacking in detail. I ended up having a whole connector in my car not connect to anything on this unit, which worried me...but I learned that this was to be expected. . . .
perfect fit,easily adaptable.
Radio Replacement Interface (for Toyota/Scion/Lexus): The PAC RadioPRO RP4.2-TY11 radio replacement interface is designed for 2003-2016 Toyota, Lexus, and Scion vehicle models. The module enables installation of an aftermarket radio while retaining the factory steering wheel control functions as well as maintaining compatibility with the factory JBL and JBL Synthesis amplified audio systems, the built-in 3.5mm auxiliary audio jack, and factory LCD. The built-in USB connection and back-up camera can also be retained in conjunction with an optional adapters (sold separately).
- Adjustment of the vehicle settings through the original radio's vehicle settings menu will be disabled after installation of your new radio. It is advised to make sure all settings are as you desire prior to removal of the original radio.
- Does not retain Rear Seat Entertainment (RSE).
Vehicle Compatibility: The RadioPRO 4 RP4.2-TY11 is compatible with the following 2001-2016 Toyota, Scion, & Lexus vehicles.
- Only compatible in Toyota Avalon vehicles equipped with a JBL system.
- Not compatible in Lexus vehicles equipped with factory navigation.
Radio Select Switch: The radio select switches on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle. The RP4.2-TY11 is compatible with Alpine, JVC, Kenwood, Clarion, Pioneer, Sony, Jensen, Fusion, Advent, Boyo, Dual, Lightning Audio, Rockford Fosgate, and Visteon aftermarket radios (see owner's manual for appropriate dip-switch setting).
For Amplified & Non-Amplified Systems: The PAC RadioPRO RP4.2-TY11 can be used in vehicles with amplified & non-amplified factory audio systems. It retains JBL and JBL Synthesis amplified audio systems with real-time and programmable speaker fade function.
Note: Aftermarket radio features such as High Pass Filters (crossovers), DSP or "Network Mode" will interfere with proper fader function. In order for the RP4.2-TY11's fader function to work, the audio from the aftermarket radio's output must match so it can compare the front and rear audio levels and determine the proper fader setting for the factory amplifier.
Programmable SWC: 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 or create secondary functions. The SWC functions can be easily programmed; see default SWC button assignments in the included user manual. 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 and newer JVC receivers. The 3.5mm jack supports Alpine, Jensen, Older JVC, Clarion, Pioneer, Sony, and Dual radios. Not compatible with Soundstream head units.
Factory Aux Input Retention: The PAC RadioPRO RP4.2-TY11 radio replacement interface module retains your vehicle's factory 3.5mm auxiliary input. Your aftermarket stereo must be equipped with a rear-panel Aux input (RCA-to-3.5mm adapter may be required).
+12V/10A Accessory Output: In many Toyota/Scion/Lexus vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. PAC's RP4.2-TY11 is designed to provide a 12V/10A switched accessory output (red wire).
Navigation Outputs: The PAC radio replacement interface provides wired outputs for navigation radio installation; including a VSS (vehicle speed sense), Parking Brake, and a Reverse Gear output to make installing an aftermarket navigation head unit simpler and less time consuming.
Note: Navigation outputs not retained by all vehicles.
Retains Factory Info Display: The PAC RadioPRO RP4.2-TY11 radio replacement interface module retains the factory info display (when applicable). Make sure the interface module has the latest firmware version installed.
Optional Factory USB & Backup Camera Harnesses: You are also able to retain your vehicle's factory USB input and backup camera in select vehicles with an optional harness: CAM-TY11 or CAM-TY12 (retains backup camera), or AX-TOYUSB or AX-TOYUSB-2 (retains USB input).
RadioPRO App: PAC offers a Windows compatible RadioPRO App software program to help you configure the interface. Use of the RadioPRO App allows you to do the following.
Note: The interface must be connected to the vehicle and your Windows laptop when using the RadioPRO App.

Any time you're installing an aftermarket stereo you're going to need a wiring harness to interface to the factory wiring of your specific vehicle, and if your vehicle has steering wheel controls and you want them to work with you aftermarket stereo you'll need that adapter too. Crutchfield takes the guess work out of what harnesses and adapters you'll need for your specific vehicle. [ Frank Jul 30, 2017 ]

I am not sure. I can only imagine that it is on because not all input/outputs are being used.mine was red as well and everything works fine. I don't have steering wheel controls or navigation applied so it may read it as an error. [ Larry Jul 03, 2016 ]
