ON PHYSICAL BUTTONS: this software has only been tested on head units with no physical buttons (like volume) | Before making any changes, access the CAR SETTINGS -> FACTORY SETTINGS -> ENCODER SETTINGS on your head unit and take a screenshot of the current settings (see example below). After installing the package, go back to these settings and adjust them if needed. If that doesn't help and if you can't successfully re-calibrate the buttons after installing the firmware, restore your backup

Disclaimer

I do not create the software itself but rather use research and put together different mods and hacks into one package that includes very user-friendly step-by-step instructions on how to install it all. You will find the links to original posts in the instructions pdf's if credit is due. The software might include smaller changes made by me and has been fully tested in real units.

This firmware works on the following 1Gb RAM and 2 Gb RAM units with fake Android 8.1, 9.0, 9.1, 10 and Android 11 installed,

with screen resolution of 1024x600 px.

It will not work on Tesla-style units:

- YT9216BF | YT9216CFJ | YT9216BJ | YT9216BFJ | YT9216CJ

!! TAKE A PICTURE OF YOUR SYSTEM INFO AND KERNEL VERSION BEFORE DOING ANYTHING TO YOUR HEAD UNIT !!​
