I am trying to change or add an amp to the stock system and was wondering if any one has the wiring diagram for the stock head unit. I am sure it is out there and some of you have it. Would appreciate the help
thanks in advance!

Hi gago,

I have the wiring diagram(s) that you're looking for, but unfortunately, the "on-line manual", won't allow me to copy/paste any of those pages (which are quite a few), to this post.

The only thing that it would let me do is copy the URL to this page, so here it is. Do it Yourself Automobile Repair Manuals - Mitchell 1 DIY

The latest model 4Runner available is 2011 (SR5, TE, and Limited), but as you know, the diagrams are basically all the same. It's not very expensive so I registered for three years, hope this helps.

rigtec, cheers.

This is what I got from someone who has access to the Directed Electronics wiring information database. Most of the wires seem accurate when I was doing my alarm install on my 12' TE w/ nav. Hope it helps!

Thanks guys, I appreciate it!

Don't know if you're still interested, but the "optional JBL nav system", has it's power amp located in the R/R storage compartment, over the wheel well.

The "non-JBL nav system" has it's power amp, built-in to the head unit. I'm still trying to find a way to copy/paste the pages that you want to see, here; I'll let you know if it can be done.

If you P.M. me with your email addr, I can attach it to an email, and send it to you that way.

rigtec, cheers

Thanks

Very useful pinout information. Thank you!
I know devices like Beat-Sonic gets the touch command from the receiver display somehow. In other words, Beat-Sonic Apply Car Play device integrates with the receiver's touch screen as an external device.

I am thinking to program and integrate a Raspberry Pi to the OEM receiver and add the Apple Car Play and Android Auto functionality. I have already managed to install these on the RP (easy step), pending integration (challenging step). In order to achieve this, the RP should be able to receive the touch commands from the receiver. Do you have any idea what pins of which port carries the touch signal? is the from the CAN Bus?
or if that is not the case, do you have any idea how Beat-Sonic reads the touch commands from the receiver and integrates with the headunit?

Appreciate!

Awesome thread .. thanks
