JoyCon EXR connection for Steering wheel controller
 

Hello Team,

i have 370z 2016 base model, i am trying to install Samsung Tab A 10.1 in the car, i have 2 challenges as below, i appreciate everyone input. PS i took it several car audio installer, and they have no clue.

1- steering wheel controller:-
i bought Joycon exr a few days ago, i tried installed and mapped to left side controller for media control. i managed to find 2 OEM wire harness (white and Black) for joycon, when i run auto detect it just detect (UP/Down/Source) buttons but i can't detect volume+ -, is there a separate wire for volume controller? If yes which color wire would be.

2- How to auto turn on the tablet, in case if Tablet died,

i tried root the tablet and change IMP file, that didn't work,
i tried ADB command (fastboot oem disable-charger-screen) ( fastboot oem off-mode-charge 0) no luck. any idea how?


apologize for inconvenience English is my 5th language:tiphat:

One of the stereo gurus should jump in about the wiring. You might want to download the FSM - it has wiring diagrams, wire colors, connector pinouts, etc. Link in my sig.

Thanks man you saved me a lot of headache, the link have a lot of useful documents, and i found the color code.

Scope22 what about Joycon?

Here are the instructions for how to root it to have it automatically boot into startup once power is detected (should it die).

To be honest, it was a real PITA getting this to work to the point I gave up and had one of my friends who's smart with tablets/rooting/etc. handle it for me; he was able to get it working pretty easily though.

He linked you to another post with information on how to wire it. I'm about to order my Joycon next week.
