If it does not say MTCB/C/D/E in the MCU description then it is not any of them. There are many MCU variants out there.

Sorry mate, I can't help you with that one. If it's quad core it seems like it's an older unit. Could be a QD unit. There seem to be three main manufacturers, FYT, MTC and QD.
P.S. Please give me a thanks if you appreciated the little help I could offer.

erisin ES3261F

good evening, I have an android erisin ES3261F and I wanted to know if it was possible to download a new software since I tried bugs with the original one. Sometimes it no longer reads the can-bus control unit and the application of the radio overlaps the writing of the frequency with that of the song titles.

help android head unit yessun

Hello
I bought 2 years ago an android 6.0.1 car radio type head unit on aliexpress and I would like to update my android but after seeing another site and forum all talked about andoid version px5 or px3 .
And to know the type of car radio you had to go to "about the tablet" and take the given reference.
the problem being that when I go to this parameter I can't find a PX reference ...
I have:
- android version
-Processor information
- baseband version
-system information
-mcu version
but none with a PX reference.
Thank you for your help.
PS I am from France and go through google translate to write.

AC8227L Roms - Chinese headunit stereo

Hi all,
I have seen a few Roms here and there for AC8227L but I have a few questions, hope someone can guide me.
Is there a guide to backup the device completely before upgrading so that you can go back to the original rom incase of any issues?
Are there any roms that allow bluetooth pin/code input? I'm unable to connect to elm327 obd2 bt scanner cause I'm unable to enter a password. The obd2 scanner works on my phone, not on the headunit.
Are there any roms that are smoother/quicker? The fake 8.1 is really really slow.
Also any detailed guides for installing the roms? I couldn't find one or maybe I'm just too anxious to use one that isn't specifically made for this device.
Any tips and tricks to get the best out of the headunit? I have used HU reloaded and android auto works decently as long as you keep the resolution low. Youtube is really slow.
Can I install different apps for handling Bluetooth connections and/or Bluetooth music?
Hope someone can help. I've attached screenshots of my device so that I can get relevant information.
I have no issues flashing roms on my phones but I feel really anxious/uncomfortable flashing a rom on this, probably cause of a lack of information on what works and what doesn't.
