    CX-9 infortainment connector diagram for AIO tweaks hack

    I am trying to install AIO tweaks on my CX-9 year 2018. After I open the unit, I found out that the connector is different from the other modelís unit. Can anyone point me out where can I find the wiring diagram of the unit? I want to know which pin is Tx and Rx. Here are the photos of the unit.

    Thank you in advance.

    I want to know as well. Could you tell me how you took out the head unit? The CX-9 has a hidden panel behind the screen. I haven't try to pull it out yet as it seems a bit hard when I try to pull out the front panel of the vent to access the screws.

    Hi
    Here is the manual how to remove the unit. It is not hard if you using the right tool. However, I am still searching for the unit's diagram.

    Credit: thanks to jellyfish11 who post this manual.

    If you can take some picture of the 1) serial ports interface of the display unit after removal and 2) their plugs into the console, I'm gonna send it to Bijan Albuyeh who wrote incredible tutorials for programming mazda infotainment systems, after giving me permission of course. He may work something out and know which goes with which.

    Additionally, for anyone who wants a video tutorial for display removal, here's one:

    Thanks, Randomstuff, that what I want. The video shows how to remove the whole unit to get into the ports. I didn't' see the ports because I didn't remove the whole unit.

    Very awesome Randomstuff. Let me see if I have time to pull mine out. Basically you want a picture of the connection for the screen and console right? Therefore I need to pull out the screen and the console and take pictures of the connection ports.
