PAC RadioPro4 TY111 Black Radio Replacement for Select Toyota(R) Vehicles

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.

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.

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

The controller supports either JBL or non-JBL factory Toyota systems. There are lots of connectors to figure out and the instructions aren't very clear. It would be nice if they offered more detailed online connection diagrams like their competitors. Although there is factory camera support, but the voltage output was measured only at 5.1V, so it didn't power on the factory camera that needs 6V to function. However, this is the only controller that offers front-back fading when used with the JBL system, others don't. There's also a gain adjuster when using the JBL system. The integrated SWC and AUX support are nice. First, make sure you upgrade the firmware to the latest through RadioPRO, downloaded from their website. Then plan ahead where all the collections go, and it will make installation go smoother. Overall, it's a nice controller.

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.
