I searched on google and on this forum and maybe theres a simple reason i cant find much info about this unit.
what customizations can be done? is there custom software? Id like it so the weather shows when it starts up or something.
Im primarily using the bluetooth feature to play music but im having troubles with the sound quality. can I use a different amp software through bluetooth?
Im also planning to connect 1 or 2 amps to it. I see it has subwoofer control. anyone have any experience using a sub amp or a 4 channel amp with these android units?
I also cant get a 3g dongle to work when I have it connected. im sure its something im overlooking this is the one im using smile.amazon.com/Unlocked-Huawei-E397u-53-Worldwide-Required/dp/B01M0JY15V/ref=sr_1_2?s=electronics&ie=UTF8&qid=1504553313&sr=1-2&keywords=Unlocked+Modem+USB+4G+LTE+Huawei+%27"]Unlocked Modem USB 4G LTE Huawei E397u-53 Worldwide Hotspot Service Required Only T-mobile in US
more or less I want the best sound quality, total control of my amps and just to know what cool stuff you can do with these things. thanks!

Use the image-file from yandex.

For this MCU update,do we need only img.file or and cfg.file together copy in root folder ???

Yes, MCUs are not processor or OS specific.

Thanks a lot for this, can anybody guide me how to figure out which one of these I need to install. My device mcu version says: 023042bGS-CIC-HW7-180516[B1280_170325].
I Guess it should be GS

If your MCU does not start wth "MTCD" or "MTCE" its not MTCD/E unit, try the Android Headunit general forum.

Thanks I found the right one finally but the hu says please wait and news starts the process.

Can you share a link to the file ?
And post a screen shot of your MCU ? (it should b "v2.56" not "Vs 2.56").

As far as I know you can, but Sofia mdels have the wifi on the SoM, so the MCU may have some differences, do you have a copy of an older CHS MCU ?

No, I'm sorry, I don't have any copies. I bought it from a friend. What do you think I risk? I would like to try to update it because I have problems with Bluetooth or do you think it can solve maybe changing roms? But even I wouldn't know where to start, which rom I could put and how. Thank you

Usually all MTCD/E units use the same MCU and I was always under the impression Sofia units did too, but as I said they have wifi on the SoM which may make a difference as on other MTCD/E units the wifi is on the motherboard, so I m not 100% certain, also the link you posted has "Sofia MCU".
So I would read this thread starting at the beginning to find out for sure.

Hi, did you succeed with any update? ROM or MCU?
I have a similar MCU CHS 2.51, BT frequently needs a complete 10s-Powerbutton reset to work....
Tx!

Hi, I also have your same problem with the bt. No I have not tried to update I am afraid of breaking everything not being so heady

You could try changing the MCU to a different one - see @marchnz's "Verified Cross Compatible MCUs" thread.

MCU wanted for MTCE_GS_V2.84._3 (dmcu.img)

Hi All,
I accidentally messed up with my unit PX5 (buttons are not working - unit does) and I would like to reflash the MCU.
The original version the unit came with is MTCE_GS_V2.84._3 but I cannot find it anywhere.
Does anyone have an idea where I can find it?
Thanks a lot

set buttons in factory menu.

Already tried and added a new post reply here https://forum.xda-developers.com/showpost.php?p=77438369&postcount=1968.
When i try i get no response. Should i long press ?

I see here https://yadi.sk/d/umCvHqCDzHccr/RockChip PX5 Android 8.0/GS that only ROMS for PE series are available . Mine is a Xtrons PB series (PB68WRJP). May I use the PE ROM ?

they will be fine with your pb i have the audi TT pb unit and have used these files for mine without any problems, as far as i am aware the px5 units are all the same anyway.

I asked because my seller gave to me 2 versions of the update file a couple of months ago. First he sent the PE version and later, before I updated my unit, he sent the PB saying that this is the right one for my unit.

Update MCU (PX3)

Hello! I currently have this version of MCU: MTCE_LM_V2.75_1
Is it important to update MCU? Are there risks? After the installation should I configure something?
From the radio I can not update MCU, it does not find any update. But in a post of this forum (Dasaita) I have seen an update is it compatible with my radio unit? MTCE_HA_V3.06.zip
I have a PX3 of 2Gb.
Thank you

I just found this MCU file: MTCE_LM_V3.01c20190111 better this update? I do not know what is the latest MCU version of MTCE_LM_V2.75_1

It's better to keep it up to date, even when you dont experience issues with the device.
The updates are normally not that hard to install and version 3 has the function of teleconference within.
I noticed with my upgrade that the device doesnt freeze anymore during boot. But i had 1.9 installed and now 3.00

Could you tell me what is the most updated version of this MTCE_LM_V2.75_1? PX3 2Gb. Thank you

I thought the rom for the MCU is 3.01 for LM, you can find those on the forum, only a good search is required.
I have the GS version but i do not recommend installing an MCU from another supplier.
The android PX3 2GB roms can be found anywhere. Search for PX3 ROM LM.

Your unit is not an MTCB/C/D/E, asking in the wrong forums. Read on.
This entire thread is a waste of space in that there are more appropriate places the OP could have posted in or at least searched first, but that's another matter.

I have a MTCE_XRC_V2.79k_1 which has the Intel Sofia cpu. What MCUs can I use?

Anyone reading this
*** Do not flash the DMCU.ext listed here together with the MCU ***
OP please edit this post, there is NO reason to flash dmcu.ext when flashing the same vendor MCU.
Suggest expanding on the comment "no worries just reprogram", with clear examples if making this statement.

Hi all I am a bit confused by how many different downloads please excuse me as a noob and first time flashing my PX6
My question is can I just jump from 3.5.8-1 to the latest 3.6.2 I believe and what files exactly do I need to load onto a flash drive.
Your help in advance is much appreciated. Cheers J
I am running a MTCE HA running 3.5.9

Suggest NOT changing your MCU unless resolving a known issue. Same for Android. This is a head unit, constantly updating isn't necessary.

Update for mic issue
Hi Experts! If I want to update my Dasaita PX6 Max10 is there any preferred order which update to do first OTA or MCU? In case of OTA update at starting is it necessary to click on WIPE AND FORMAT FLASH option? Somebody is doing this, somebody is doing that... When is it suggested?
The reason why I planning to switch to latest update because during calls my mic is working strange, sometimes the others cannot hear me properly. They are complaining about low volume and faded voice. (If they are calling back they says it is better...) Have you experienced the same thing?

I use the internal microphone, not yet tried an external one. I checked the mic with apps, basically it is working however its volume seems to be a little bit low, but it is not faded. I feel it is rather a noise suppression issue (coming from sw side), therefore I hope that an update could help.

I respectfully disagree based on years of experience: there's no need to flash the MCU configuration file DMCU with an MCU that matches the manufacturer of your head unit. I.e. HA to HA, JY to JY etc.
Your well meaning advice resulted in a configuration not appropriate (which messed up the screen) for another members screen type/resolution.
The 'similar issues' stated are probably your misunderstanding of what the DMCU file is and possibly where others have installed a different vendor MCU. E.g. GS on HLA

Hello, with dasaita px6 android 10 1024/600 firmware HA3, the update "HA3_rk3399_10.0_ota (20200915) 升级 包" and MCU "MTCE_HA_V3.62": all is ok , thank you

A few questions...
1) Anybody able to modify steering wheel controls? I open the app and it is blank.
2) Also, can you summon siri/google via the steering wheel when in carplay/android auto?
3) I have an OBD dongle but am unable to get the headunit to connect to it. I see it in the available devices but nothing happens after i select "yes" to connect.
I have the max10 600p resolution version for highlander. A canbus was included and I am able to change vol/toggle modes.

When you install a harness with a CAN adapter the steering wheel signals a routed for you to the CAN decoder box. It worked for me to reroute them to my own circuit. It should be equally fine to connect them to the KEY1 and KEY2 inputs, that is if your car has resistive buttons and only one or two. Then you can program them as desired.

Flashed 20200915 and the 2.62_1 (with a different dmcu.ext provided by dasaita that had screen:18 inside it). Everything has been working great but there is an annoying notification everytime I switch the car on that shows the version number - is there anyway to get rid of this?

I noticed that the first time I installed that update, then I went back to the prior version I had, one more time I gave it a try and I started to try to remove that annoying notification, but then I thought why waste time on that, also I notice that saving a screenshot was giving me an error, so once again I went back to the prior version I had installed.

I can’t decide whether to put this up or Malayk’s ROM. I don't really need pre-installed programs, I know which launcher, music player, etc.. I want to use, but there may be settings in it that I can't solve on this ROM.
