PAC Radio Replacement Interface for Toyota, Lexus & Scion Vehicles (04-19)

It works just as advertised. I even bought mine "used" on Amazon for a fraction of the price and it arrived in original packaging basically open box. Model PAC RP4.2-TY11 Radiopro4 Ty11. My application is for 2005 Toyota Solara with factory JBL amp. I chose this model harness because it includes connections for steering wheel controls and fader. The wiring looks menacing, at first. 4 page Instructions walk you through it but appear to have been written with a professional installer as an audience. Some tips: ALLOW PLENTY OF TIME FOR THIS INSTALL. On a day prior to the install, familiarize yourself with all the terminals of the harness (they are labelled) and read the instructions, every word, over and over until it's totally clear to you. They are detailed and somewhat complicated. But it's totally doable. Call PAC tech support if it's not clear. There are a few unused terminals which you will need to insulate (I used heat shrink tubing, but electrical tape would work). Alow at least 1 hour to connect the wiring from this harness to the harness provided with your radio (I used and strongly recommend Posi-Products screw type reusable quick connectors). During the install, test every feature prior to reassembling the dash. Really, the install into the vehicle was the easy part. I am 51 and this was my first install since the 1980s. I pulled it off, so can you.

Replaced the JBL head unit in my wifes 2011 Venza and this worked perfect. You can still use fader front to back and left to right. Also kept the steering wheel controls. Only thing was it came with older instructions that didn't really clarify how to connect steering wheel control wires. (Missing 1 wire color connection) After going onto there website and looking up the model, the proper updated instructions were found. The swc ground wire is already grounded so no need to worry about that. Just connect key1 & key2 wire to proper vehicle harness wires and you should be ready to go. That was the only confusing part but ended up being so simple in the end. I Overthought it! Lol Oh and make sure the little plug is in the unit good. I had to pull head unit back out a few days later after losing sound to some speakers. I ended up just pushing the little plug on the side of the module in a little more and problem solved..

Works great for my 2017 Corolla SE so I'm hoping to let people know who may have the same car.. Easy install but I had to call them a few times. I used with the CAMTY12 and USBTY1 to keep my factory backup cam and factory USB. The song skip doesn't work every time though :\ You plug the USBty1 into the USB port of your radio that you would normally use for Carplay, and then you connect to Carplay through the factory port. I had to call about the backup cam but I forgot to connect the violet wire to my reverse on the head unit. Also, make sure you connect the parking break green wire, because I didn't and I had to unhook it all and wire that up.

Incorporating this wiring harness in the installation of a new head unit was a lengthy process. The manufacturer directions aren't great, but if can be inferred somewhat reasonably if you compare it to the instruction manual that comes with your new head unit also. Simply match the head unit inputs/outputs wire-by-wire with the inputs to the unit and use a wirenut or another connector to bring them together. Then match up the male plugs from the unit's wiring harness to the female plugs of the vehicle's wiring harness. Some of the plugs may not be used (they weren't in my vehicle at least). All of the advertised functionalities, like steering wheel controls and integration of the stock audio system amplifier, were maintained except for the aux cord. The factory aux cord plug doesn't work, but you can leave an aux cord plugged into the back of your head unit and thread it to somewhere you can use it to circumvent this problem. I also appreciated the high quality of the unit (both computer and wires (seemed sturdy, stripped well, and not too friable)). Also there was minimal setup/programming required upon completing install. Would absolutely purchase again if I got a different vehicle and would confidently recommend to a friend.

This item is trash. For $90.00 you would expect this to work properly but it does not. Sound cuts in and out on all speakers after being installed for 3 days. It's shipped from a 3rd party seller so if you want a replacement you have to tear your dash apart and leave it apart for however long it takes to get the new one or put it back together without the harness just to take it back apart again. My car is a 2008 prius with JBL and navi. Maybe the Metra TYTO-01 will work better but the reviews say otherwise. I don't recommend this product unless you don't care about the quality of your sound and often only hear sound coming out of 1 speaker at a time. Update on 10/01/17 - I ended up having to bypass the factory amp in order for everything to work properly. I only recommend purchasing this if you plan on bypassing the amp as well. At least in a 2008 Toyota prius. It works well as an interface for an aftermarket radio but causes problems with the factory amp. No problems from the MID yet.

I used this interface for My Lexus Xr 330 2006 no JBL and No Navigation, is not easy as it looks , but work once you figure it out, Has everything, Bypass the analog amplifier and retain SWC is already programed on the basic functions , select the dip switches than correspond to your aftermarket radio you will install and Separate the cables that you don't need, cut or caped and work plug and play.

I'd probably knock off half a star for the documentation if that were an option. Don't get me wrong, its certainly written in clear english, but often seems to assume a high degree of familiarity with various aspects of modern car audio. Personally I had to remove the head unit several times to rewire or adjust various things, but in the end got it all working. On my 07 avalon with JBL: Climate controls, Nav, front/rear fade and SWC all functional. Sound quality is good. No noticeable noise/distortion. Used to install an alpine ilx-w650 and its certainly its an improvement over the stock HU. Wish it came with male RCA ends on the audio inputs. Would recommend ordering some, ideally solderable if you're able to do that. Also, when you remove the stock stereo be sure the EQ is flat, and turn the volume all the way up (whatever the volume on the stereo is at time of removal will become the max volume for the PAC interface -at least on my vehicle). Overall I'm happy with the product. It does seem like a good value compared to the cost of separate units for the SWC, amp integration and a relocation harness. Not to mention saves you from the headache of the "old way" of relocating the factory radio I'd seen shown on some youtube videos.

I installed this with a JVC 2660, and it's working great in my 2013 Toyota Highlander. Don't let all the wires scare you. Mostly, it's putting colors together, and these come with way more than they need. It's not too bad at all. I used Posi twist connectors for my wiring. They are super easy and are working great for me.

Nunca funcionó, mi instalador ha hecho varios intentos pero no funciona.

Exactly what I needed for my alpine head unit in 2011 Tacoma. You’ll want to by the brake bypass. You need it, it’s like $20 save yourself tons of hassle.

Good wiring harness and was easy to install with my clarion touch head unit.

This product was received broken and would not function when connected. Sadly, the option to return the product had already passed by the time I learned the product was defective.
