Hey guys, I recently picked up a 2006 Sienna Limited AWD and it has all the bells and whistles including a JBL 10-speaker nav system, bluetooth, steering wheel controls, and backup camera. I popped out the nav unit and sold it as I will be swapping it out with a Pioneer unit that has Carplay. (AVH-2330
I am trying to retain as many of the factory features as possible but finding info on the navigation/10-speaker units seems to be nearly impossible! I found some wiring diagrams via Autozone and I was able to make my own pinout charts. I'm not quite sure what everything does but I think I have found most of the important stuff. I will be probing around in the car to confirm sometime this week. I was hoping that someone could help fill in the blanks.
Ideally when I am done the van will still look stock but now have a new Pioneer deck with Carplay in place of the stock unit. I will be able to send AUX/video in from the stock AUX jack on the dash, and maybe even send video out from the HU to the rear entertainment. I will retain the stock backup camera.
The plan is to use the PAC RadioPro4
to interface with the JBL amp such that the pioneer deck will talk to the JBL amp which will in turn drive the 10 speakers. I have all the wiring for that figured out as most of it is pre-terminated.
For the backup camera I believe I have the right connectors and pins so I can send 6v to the camera and grab the composite video signal and feed it into the pioneer HU. I bought an adaptor
so I don't have to chop up the factory harness. This will be connected to the reverse wire to trigger the head unit and camera power.
I think the dash mounted AUX input might have audio and video input as the Blue connector (B) has a video wire on it. If so I could wire this directly into a 1/8" connector and into the rear of the pioneer allowing the existing AUX to send video/audio directly to the pioneer.
I'm not sure exactly what the black connector does but I'm guessing it sends audio from the head unit to the rear entertainment system. I'm not sure if this is line level or amplified. The PAC interface will only use the front speaker outputs on the HU to send L/R audio to the JBL amp. It has rear speaker outputs and rear RCA outputs available.
However, if it is an input from the rear entertainment into the head unit as an audio source then I will definitely want to grab that and use it as an input into the HU.
I will be replacing one of the two 12v outlets with a dual USB connector
. One end will be connected to the HU for CarPlay, one end will be connected to a car charger.
will connect to the parking brake to unlock the Pioneer features like settings while in motion.

Any info you guys have would be greatly appreciated. I plan on compiling my collected info into a solid wiring diagram for others to follow.
