This is a known issue, a friend has a px6 android 10 and the subwoofer control equalizer also doesn't work. He tried updating the MCU and the firmware and nothing helped. Unfortunately, we didn't come up with anything.
Hi,Compiled list of MCUs for MTCD from 4pda.ru- the website is in Russian.
Exact version numbers of each MCU is currently unknown; only the release date was provided.
These MCUs are for MTCDs with RK3188 CPUs, compatibility with the newer MTCD with Intel x86 CPU is untested.
What is the MCU?
MCU stands for Microcontroller Unit- wiki. The MCU acts as the bridge between the hardware on the head unit and the android system. This allows for special interactions between the vehicle and the head unit that would otherwise be impossible through Android. For example, backup camera view can be activated even if the android operating system hasn't finished booting up. However, the nature of the setup inherently includes a major drawback because the MCU is proprietary. This means software relating to the MCU can only be updated by the specific manufacturer/seller of the head unit. Any problems or bugs in the MCU are unlikely to be fixed unless the manufacturer releases an update- i.e. the bluetooth problem. This thread serves to help remedy this issue by consolidating the scarce amount of information available on MCUs and to build on related community efforts. There has been some progress on modifying the MCU for MTCBs in the XDA and 4PDA forums by kumarai, darkleo, and Dark Simpson. No progress in modifying the MCU has been made for MTCD.
How to find your specific MCU?
On your MTCD head unit, go to the 3rd line under "MCU Version" in Settings > About. In the image below, the MCU is "KGL".
This image was taken from a MTCB thread, don't worry if the other specifications are different because your unit is MTCD- not MTCB.
Only use MCU that matches your MTCD head unit's MCU or risk malfunction! Update at your own risk!
Again, dmcu.img files are not interchangeable like dupdate.img files regardless if your head unit is MTCD or MTCB/C!
It would be greatly appreciated if you can post feedback after updating your MCU.
List of Updated MCUs:
KSP (CUSP?)
Accessing Recovery: Press and hold the volume dial until the head unit LEDs flash 3 times. Then immediately release and press the dial 1 time.

Update Instructions
In order to flash the updated MCU, you must rename the downloaded "*.img" to "dmcu.img" then place it in the root directory of your SD Card or USB drive.
Insert the medium into your head unit then access your its recovery and choose to update and wipe- it's the same process with dupdate.img files.
If the provided MCU is zipped with "dmcu.ext" and/or "dmcu.cfg" files, include them in the same root directory as your "dmcu.img" file and flash in recovery.
If you have ANY additional information or older/newer MCU .img files, please post here.
Thread will be updated regularly as relevant information is posted.
This looks like the best place to ask. I have this model of head-unit (attached images)
Car is a Mercedes A180 Avantgarde 2006 if it makes any difference.
Bluetooth music sounds a bit funny, and it refuses to connect to my phone on bluetooth and wifi intermittently (sometimes it does, other times no).
I figure I need the latest dmcu.img & update.img to install. Would you be able to show me where exactly I can find them? Tried your links but was insecure re: which exactly mine is
Thanks a real lot in advance!

so, your unit is a MTCE, based on KGL manufacturer:
You can get the latest availblae MCU update on:
and your system is a PX5 unit under Android 6.0.1.... probably your Bluetooth Chipset is a MD725 (you have to chekc it on factory settings - Pass: 126)
Even exist Android 10 for PX5 units, i dont think you could get Android 9 if MD725 bt chip
hey lads need some help here. ive got MTCE_YB_V3.71_1 and im wondering if there is an update for it (yes ive searched everywhere i could). its a px5 unit running android 10

hello I have an Isuadar model PX6 multimedia radio for an Opel Zafira 2011.the multimedia radio comes with the firmware MCE_LY_V3.52_1. I have problems with the radio because when the stereo signal is lost, the radio stops being heard for 2 seconds. I don't know if it's a problem with the stock apk of the radio or with the device itself. I have used other apks, such as Navradio+ and the same problem continues.Is there any solution?.All the best.

أريد تنزيل إصدار MCU لتحديث البرامج الثابتة mtce_ksp_v3.01_1 ديسمبر 18 2018 13:55:18 android 8.0.0
i want to download the firmware update mcu version mtce_ksp_v3.01_1 dec 18 2018 13:55:18 android 8.0.0
Hey Brand New here so a few months ago I was able to use this sight to aid me in upgrading my all winter t3. Still working great and faster than it was.
So now I'm working on a eonon px3. Current mcu: mtce www v2.65d 1
Cpu is arm cortex [email protected] ghz (x4)
So was reading that going to download the file you provide and put it in the root folder of an SD card and use GPS slot. How do I get to recovery mode to start the update thank you ahead of time

So thank you for getting back to me. However my head unit is a double din. And my SD card slots are on the face of the radio not on the side
And so?
If you don't understand your system then don't post please. Read first and understand what you bought
