Finally, I figured it out! I modified the Diamond Button SW Control for my 12.3 Android unit

The 12.3" Android unit does not allow to customize steering wheel controls, as it is an FYT 7862 unit using CanBus. All steering wheel controls are hence hard coded.
But there is a way to intercept this signal using 3rd party developed middleware and make it do something else in the unit. In this video, I detailed the instructions on how to do this using the FytHWOneKey.apk app.

If you have a timeout try running this command with a Terminal application (you can download a terminal app from the Google store) "setprop service.adb.tcp.port 5555" it will enable ADB listening on port 5555 then restart
If the issue persist, go to the following link and copy the config.txt and LSEC files into a FAT32 formatted usb drive and connect it to the USB data port. Let us install and then reboot. This should take care of the issue: drive.google.com/drive/folder...
As an alternative, install the FET tool app in following link, open config.txt and add the following line “service.adb.tcp.port=5555”, then save and reboot: github.com/hvdwolf/FET

This application uses a modded combination of the com_syu_ms.apk and a Config.apk. This combi allows you to change the "hard-coded" steering wheel buttons in case you have/use a CANbus. However, it doesn’t work in our units. We need an expert android developer to take on this and make it work for our units…

This is why I love European cars, where you can change parameters on the fly. Great video, Sir. Hope you had a joyous 3 day holiday weekend.
