PACRP4.2-TY11 Radiopro4 Ty11

Worked on my 03 4Runner with JBL sound system. Used it to pair my pioneer double din

Took googling and guess-and-check to fully get set up. Optional connection points weren't documented to specific vehicle configurations, and specifications of each port's pinout would have been welcome.Successfully controls the fader in my 2009 Camry by detecting differences in input volume from stereo, provides chime and steering wheel control (SWC).Expect an hour at least to get it all set up including dialing in the gain and configuring SWC if the stock config isn't sufficient.

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.

Needed a new kit for Best Buy to install a new radio. Fast shipping, all parts needed were there.

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.
