Hey :)

I don't know if you might be able to help me, i've read some answer but since i'm not a native english it's hard for me to understand well.

From what i've read there is better MCU than other for better update/upgrade ?

From these two pictures, which one is the "best"? Or maybe both of them are good?

From these two pictures, one is from Mekede :

And one is from Srnubi :

[MTCD Android Head Units General] marchnz:
In either of those, where do you see the MCU starting with MTC(D/E/P/H).

Posting in the wrong forum and wrong thread.

Attached. Personally I liked more the old stock launcher that shows up in the marketing images, more icons on the main screen.

New launcher: swipe right to get to the rest of apps (except the ones you already have in main screen). Old launcher: buttons in launcher to switch between all apps and launcher main screen.

Actually I don't recall that in my case. I had the car logo and hard buttons set, didn't change after MCU update. Android update went without wipe, so again, no settings lost.

Cannot tell about radio presets, as I'm not using it yet (fitting issues because of radio antenna adapter....work in progress for fixing).
[MTCD Android Head Units General] Sehmee:
[MENTION=3202354]bobbi1984[/MENTION] do you use another launcher or? As I see your attachment.
[MTCD Android Head Units General] dongali:
According to Malaysk, there is an issue with google play services.

[MTCD Android Head Units General] bobbi1984:
[MENTION=7846949]Semmikabel[/MENTION], [MENTION=7408972]CadillacMike[/MENTION]: this launcher came by default after I update the system to LM_1.98c
[MTCD Android Head Units General] makes2068:
Could you please post the apk for that launcher?

Updated MCU LM_198c too, but that has nothing to do with ROM itself.
[MTCD Android Head Units General] bobbi1984:
Look carefully, I mentioned that this came from system update (aka Android update - dupdate.img)
[MTCD Android Head Units General] makes2068:
O.k., no problem.

Got the apk for me?

Any chance to backup my original MCU stored on my device? I do not found anything by searching,..

thanks a lot

[MTCD Android Head Units General] prooffy:
The "MTCD_MX_V1.97a" may solve your problem instead you asked one.. Please visit first page for it.
[MTCD Android Head Units General] bobbi1984:
which is the easiest way to extract it? without titanium and/or root
[MTCD Android Head Units General] OldRon:
If you start your PlayStore, go to the settings --> Play Store Version and tap it for 2sec... This will force the PlayStore to check for the newest Version and if needed download the latest Version... This should help :)
[MTCD Android Head Units General] Sehmee:
Was not able to even start the playstore without sign in to my Google account. But solved the issue by myself by manual updating the Google Play service. Thanks anyway :).

Still want to see a changelog of the update MTCD_GS_V1.96a_1...
[MTCD Android Head Units General] KoGi77GR:
Could you share the dupdate.img file that you installed along with the MTCD_LM_1.98 MCU ?

In the Settings-VersionInfo, what does it show at the kernel version?

I've already installed the 1.98 MCU and it seems better, so I'd like to have the newer android too.
[MTCD Android Head Units General] dortmundez:
https://yadi.sk/d/80HCGYOB33RcBS
[MTCD Android Head Units General] KoGi77GR:
I've already tried that package but while the MCU went to v1.98, the android didn't update and still shows the older version from April.

I'll give it another try though.
[MTCD Android Head Units General] bobbi1984:
That is exactly the package I have installed. Make sure you have only dupdate.img on root of card. If you have both dmcu and system, it will update the MCU.

You will know system is updating when you press "system update" and tells you if found dupdate.img and you have an option to also wipe the data. When you upgrade dmcu there is no option to wipe the data.

[MTCD Android Head Units General] Untzo:
Can you guys help me? I updated my mcu to a newer version hxd and now this happened. I think the resolution is wrong
[MTCD Android Head Units General] Pavel-71:
If you saved the factory settings in the dmcu.cfg file before updating the MCU, use it to update the MCU, all settings will be reverted.

If not so select your resolution here and update the MCU with the dmcu.ext file.

[MTCD Android Head Units General] Untzo:

[MTCD Android Head Units General] Pavel-71:
Copy dmcu.ext to a flash drive or sd card, paste it into the slot and select MCU updates in the settings or recovery.
[MTCD Android Head Units General] Untzo:
does not recognize the mcu update
[MTCD Android Head Units General] Untzo:
is my headunit ****ed?
[MTCD Android Head Units General] Pavel-71:
Try downloading the file again and formatting the flash drive to fat32. Or your device has a different way of changing the resolution, contact your dealer, they may advise.
[MTCD Android Head Units General] Untzo:
sadly the seller shop closed on aliexpress so i dont know who to ask
[MTCD Android Head Units General] Pavel-71:
Does the unit not work at all or just not respond to a change in resolution? Will you get to the recovery?
[MTCD Android Head Units General] Untzo:
the head unit works, and yes i can get to recovery
[MTCD Android Head Units General] Pavel-71:
So try to upgrade from recovery.
[MTCD Android Head Units General] Untzo:
it worked but tghe touch screen is ****ed, actually i just fixed it from factory setting but i cant set side buttons.
[MTCD Android Head Units General] Untzo:
awesome thanks dude
[MTCD Android Head Units General] Untzo:
im trying to set the buttons but when i press them nothing happens
[MTCD Android Head Units General] Pavel-71:
Did you follow the video exactly and click reset first? Or try restarting the device.
[MTCD Android Head Units General] Untzo:
yes but does not work
[MTCD Android Head Units General] Pavel-71:
And don't you happen to have touch buttons?
[MTCD Android Head Units General] Untzo:
this method does not work for me, fortunetly i managed to make it work by holding 5 fingers on the screen and that way worked. thanks for the help. also i changed my mcu to GS instead of HXD. i removed the mismatch error with the proper app
[MTCD Android Head Units General] Pavel-71:
Now that everything works, save the settings to the dmcu.cfg file and save it to the external storage, in case of problems with it, you can return everything. Factory setting / export. You will find the file in the root of the device.
[MTCD Android Head Units General] Untzo:
but i noticed a problem, the amplifier app is not working after i start the head unit i have no output for my subwoofer, the only way is to manually start it al lthe time i restart the unit. can i fix it?
[MTCD Android Head Units General] Pavel-71:
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.
[MTCD Android Head Units General] Untzo:
I fixed the problem by istallig the latest gs mcu. If you have different mcu you can install gs mcu and install unmatch remover app.

Hi,

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!

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)

Before asking for help...read....is what all of us did.....i offered help .... I sent you a video for helping and you just refused because "it is different". If your system was different i never sent you a link for a video....

So reading the mctd threads to learn about your system is the first thing you need....
[MTCD Android Head Units General] marchnz:
You're very patient and courteous ikerg. Isn't the poster off topic on this thread :)

hard to be when faced with users that join for free support then run when they get what they need and are unwilling to learn from reading.

I think support is with the seller. new members that join up because the seller doesn't support should try first, asking thoughtful question.

Can almost guarantee the poster will disappear into the internet...

[MTCD Android Head Units General] Pavel-71:
Why do you want to update it, something is not working? If everything works for you, then leave it as it is. Sometimes an update will bring more problems than good. PX30, 2gb of ram is not enough nowadays, the demands of applications on memory and processor are still increasing. You will speed it up a bit if you put it in factory settings, but not for long, it will slow down again over time. If you insist on the update, here is the MCU update, first make a backup of the factory settings, in case of problems with the dmcu.cfg file, you will restore everything to its original state. Factory settings/123/ Export/ save the dmcu.cfg file to external storage:

You can try to update it, but if the problem is in the hardware, then the update won't help. Sometimes overheating is the cause. Install CPU/GPU Meter and check if it is overheating. If so, put new paste under the radiator. Or add another cooler, passive or active, see Alex's videos. It can be more things, but that's already a job for an electromechanic.
