I've seen that hare many variations of software fromYT9216BF_00007_V004_20191226 and after the yt9216 it changes, I've no idea if will make possible the installation or not.
I admit....I'm lost

AT YOUR OWN RISK, you could try this package: https://yadi.sk/d/Faw1HGZrNCwMCQ

nitial firmware in which some of the sound adjustment functions do not work, even the activated hifi button does not work, the equalizer does not adjust the frequency of sound on the radio, partially compatible with the YT-9216 GU.
In firmware YT9213A_00005_V004_20191218_HIFI for GU 9216 / 9216_AHD / 9217 (2/32) all this already works.
I tried to leave it unchanged, but nevertheless, there was a slight modification. Namely:
TWRP
ROOT
VIPER
Radio_RDS from mclaught with the completion of the button background
Editor for radiomclaught
Window skin Settings
Skin window GPS Test
Returned the buttons and the slider in the "Sound Settings" section
Set the equalizer with the HiFi button.
That's all I ’ve done ... I don’t know how much more, unfortunately ))))
Things to remember:
Perhaps, after flashing, you will have the device’s firmware name changed to YT9213A
Immediately after loading, reboot the device
Sound on a volume scale of 17 or more -18Vol, has a slight "plug". Not critical for me.
After a full installation and overload, adjust the sound using standard tools (EQ, hIfI, Viper). I really liked the sound (installed audio processor CSC37033 and ULF PA2030A)

Skins from the stitched and working device YT9216C_AHD, under the spoiler.

I have version YT9213A_00009_V001_20200225, XY 3.1 (82227L), CPU A7 1.3GHZ x4.
See if I find out things like reset the device or update it.
I hope to find information to update it, the touch screen has phantom keystrokes.

Pretty sure it's the same as the headunit discussed here.

Forum.xda-developers(dot)com/android-auto/android-head-units/rom-firmware-chinese-7-head-unit-ac8227-t3931863

Fyi, you'll want a better microphone and solder it on

The stock bluetooth is locked down by the manufacturer. If you get a USB bluetooth dongle that is supported by the Linux kernel you will be able to connect other bluetooth devices to it.

You can use CarWebGuru launcher or Agama Launcher for better UI.

Yes you might be able to load a separate BT device and have it function with the hacked BT stack, but you won't get the standard BT stack. Period. Yes I have reproduced on my MTCD/E.
I am not exactly sure what you mean by functioning with the "hacked BT stack". Android is based on the Linux kernel and the USB bluetooth dongle is supported directly by the kernel. The software interface for pairing devices can easily be changed with apps from Google Play Store or F-Droid. I use my bluetooth dongle to pair to my BluDriver OBDII adapter which will not pair with the built in Bluetooth.
So, are you saying that I shouldn't be able to do this or is there some other point that I am missing here? Not trying to be rude here just trying to understand. Thank you.

What I am saying is that the chinese developers wrote their own BT implementation, the standard Android rules do not apply.

What the manufacturer's did to the Android software was not done at the Linux kernel level. Yes, the default bluetooth software will only pair with certain devices but that does not stop the Linux kernel from working with a USB dongle to pair with anything you want.
