Hello. Good day. I have Dasaita px3 android 7.1.2 head unit. I want to upgrade. Which core board do I need to use as hardware for this? I would be very glad if anyone could give technical information. My software starts as hct2

Running the January version of Max6 Vivid Android 11 from Dasaita's website.

Always use it for CarPlay. Got an advertisement popup that popped up over Apple Maps and stayed even when I switched to other CarPlay apps.

How is this happening? How can I disable this?

Hello Folks, i have a Dasaita PX6(1280x720) and im starting to have issues connecting Zlink with my phone. does that mean i need to update the firmware? or what seems to be my issue? its in a 2017 Toyota Camry. it worked fine up until yesterday, now it doesnt connect to Zlink
[MTCD Android Head Units General] ikerg:
Not necessarily... It could be some.kind of update on your phone's side...

Try to impair and forget your device and pair it again.... Check your android auto or carplay settings in your phone to ensure permissions are given again
[MTCD Android Head Units General] ruinertt:
Are you running Android Auto? I noticed that there was inconsistency once Android Auto's Coolwalk platform was introduced. It went from connecting every time to me manually having to mess with bluetooth (off/on) in order to make it connect.

About Android Auto: I have an Android 8 smartphone and PX6 Vivid 11. Android Auto app on Dasaita now is not named anymore Z-Link but "Auto". I tried to unpair froim BT my phone and repair it but it still not be detected by Dasaita. I updated smartphone Android Auto app but no luck.

Any suggestion?
[MTCD Android Head Units General] ikerg:
What is not working? Bluetooth or zlink?

Check on the settings (now is there) that you have activated carplay option
[MTCD Android Head Units General] mcgyver83:
Bluetooth is working, I can call and stream music via bt.

I tried also with CarPlay and the one for Android Auto (don't remember the exact menu entry) activated in the factory hidden menu but no luck.

Now i disabled CarPlay in the "hidden" menu since I have only android devices.

When I open Android Auto app on the dasaita nothing happen :(
[MTCD Android Head Units General] Pavel-71:
Do you have the original cable, sometimes the problem is with the cable? And do you have usb debugging enabled on your phone? For some phones, it must be turned on, and for others, on the contrary, it must be turned off.

I will try with/without debug tools

I have Dasaita PX6 with MCU MCTH_V3.8 which is latest, i have issued with back up camera, All other Video inputs are working Front cam Aux Cam but Reverse/backup cam. My wiring is correct. It was working for month but unstable eg: sometime on and somtime off and it's now completely stopped. i'm now use Aux input for reverse and it's annoying everytime i have touch AVIN app.

I have tried to get support from Dasaita but never have any response.

Can i flash MCU MCTE on MCTH ?

Thanks in Advance.

No one is using Android Auto wireless?

I tried the same smartphone (now I have a Xiaomi Mi A2) with another car, stock head unit, Android Auto via cable and it works like a charm.

Something is detected, waiting spinnig wheel, then stops and respin again...nothing happens.
[MTCD Android Head Units General] Ritzo90:
Can anyone tell me if two things are fixed with the new px6 on vivid11?

1. Call quality, my previous px6 seemed to ignore the attached mic and only came through the headunit mic which is unsuable when driving

2. Auto connect to wifi seemed to be hit and miss.

My px5 and px6 max11 are both faulty so I need new headunits for 2 cars, ideally with android auto.
[MTCD Android Head Units General] Pavel-71:
Have you tried unsoldering the internal one and soldering an external microphone instead? For some devices, this is the only solution. MTCD is slowly ending, you should focus on UIS7862 FYT.

FYT Android Head Units

[MTCD Android Head Units General] Ritzo90:
Sorry I'm not familiar with that. What reputable sellers have that?

I thought (not an expert) that px6 was about the top of the cycle for hardware at the moment.
[MTCD Android Head Units General] Clandaries:
I also have sold my PX5 and PX6 head units because UIS7862 are much faster, have more RAM and ROM.

BUT, MTC head units are more stable atm. There are so many small things that are not 100% at UIS7862 head units.

I hope they fix all those small things by time

Hello

I have an 2017 Dasaita 6.0 PX5 unit where i replaced the Coreboard with an PX6 from M.I.C. Germany with Android 10.

It has a M.I.C. Android version on it and in want the Dasaita Android version couse of reasons.

Can i just use this:

or do i need something else..??
[MTCD Android Head Units General] Pavel-71:
For example, Mekede/Navifly, Joying, EKIY have good ratings, read the FYT forum, there are threads from these sellers. I'm not saying that the UIS7862 FYT is perfect, but a lot of problems can be solved with modifications. I wouldn't take the PX5 anymore. PX6 is still good, but what about updates, that's a new problem, just read the forums.

The Problem with the M.I.C. is that i cant coustomize the Homescreen and i want my apps of choice where i can quick access them....

Maybe i try the Hal9k...
[MTCD Android Head Units General] Pavel-71:
Launcher M.I.C. it is fixed, it cannot be moved to the end. The solution is to install the launcher from HCT7 and drag the initial launcher to the end, then customize the initial screen to your liking, any application or widget, clock, weather... Unfortunately, you cannot remove the bottom bar. For music apps I use Ubiquity Music Widget. Install the Launcher using the APK installation, here you can also uninstall it, if it is not loaded automatically, you must select it in the settings:

HCT7Launcher3.apk

Or you can try car launchers from google play, now I am using Car Launcher Pro, check out the videos:

I have HAL9K paid mod 5.2 and I am satisfied, no problem. Unfortunately some types of bluetooth don't work well, so far the only solution is to stay on 5.1.0 and uninstall and disable Webview updates. Read the thread so you know what you're getting into.

I will give HAL9K a shot.

Since my device has a MD725 Bluetooth module, Bluetooth doesn't work anyway.

AliExpress has stopped shipping due to a stupid law passed by our government.

In the Czech Republic, we don't have such a problem, but if the goods are from China, we have to pay tax, and if the price is higher than €150, we also have to pay customs. Try to write to M.I.C, maybe they will be in solidarity and sell you bluetooth.

After looking everywhere I’ve found the right thread! I have an Android 11 PX6 MTCH but it’s currently version 3.89a_1. Would it be possible to downgrade to 3.8? My biggest gripe is that my CarPlay stays in Night mode which makes things hard to see, only switches to Day mode when I restart the system but reverts back if I unplug and plug back in. Also, sound is out of sync with my phone. Would downgrading even fix anything? Thanks in advance for any help.

[MTCD Android Head Units General] STRAIGHToutLAZY:
Here my problem started some time back I did and update to my MTCE to MTCE_HA_V3.71d when I did this update at my Bluetooth would not connect any more. So when the HA_V3.80 and it will not take the update at all. I also try hold down a little pin hole with a toothpick got it in service mode then go to the USB with file and still don't work either. I'm running PX6 Android 11 MAX with the latest version. Is there anyway to downgrade below 3.71d? Thanks
[MTCD Android Head Units General] ikerg:
Software issue..upgrade to the latest available rom on dasaita website
[MTCD Android Head Units General] ikerg:
Are you sure that you only upgraded just the mcu to 3.71d and never the rom? People issues are more related to the Rom builds.....that rom build have the specific bt drivers that load during boot depending on the chipset you selected on the factory settings.

In my case I changed from btw124 (which worked originally on the stock unit and stock software) to rf210 and everything worked again.

Mcu version 3.80 and above are for MTCH and not for MTCE so they are not suitable and beber will upgrade.
[MTCD Android Head Units General] STRAIGHToutLAZY:
Yes it's a MTCE HA V3 3.71d here is where I got it at the time https://disk.yandex.com/d/umCvHqCDzHccr/MCU for MTCD, MTCE, MTCP, Intel Sofia3g/HA . But the version 3.45 was working for me fine just thought I needed the update now I know better leave well alone . Now it's just stuck there will not accept 3.78 or 380. But I will try the other setting and hope that works. IF not is there anyway to back to 3.45 that work?

The point is - leave the MCU code/firmware alone, it's not Android so if it's not broken, don't fix it as the saying goes.

Hi everyone, I have a 4GB Dasaita head unit in my car powered by A72 and A53 and running mtce_ha_v3.65_1. Wanted to add an app to run automatically on startup but I don't see such option anyway within the launcher :/ Installing a different launcher (like Agama) that has this functionality results in more problems than solutions however cause various apps stop working :/ Is there any way to do it?

Also, how do I go about uninstalling the WebView updates?
[MTCD Android Head Units General] Pavel-71:
You can try BootControl:

BootControl - Apps on Google Play

BootControl is an application thanks to which you can add any app to autostart.

play.google.com

Webview: Go to google play, here find webview in the corner three dots and disable updates. Then go to the settings on the device, here are the installed applications and here you will find webview and uninstall updates, then restart the device, ignore any requests for updates.
[MTCD Android Head Units General] noise672:
You can also remove Webview updates directly from Google Play.

No need to go to SETTINGS.

Thank you for BootControl info, I will try.

Hi,

I have an PX6 MTCE_HA_V3.37_1 MCU on Android 9. Would upgrading to the latest Android 9 Dasaita firmware PX6 HA2_rk3399_9.0_ota(20211023) include carplay?

Was hoping updating would also fix how it can only connect to 1 BT phone and I have to manually switch phones even if the last connected phone isn't in the car.

I tried updating to HA2_rk3399_9.0_ota(20211023) but the head unit didn't seem to see the USB drive. I should be able to just use the USB ports from the car right? Was hoping I didn't have to remove the unit to upgrade it.

[MTCD Android Head Units General] marjanoos:
You can try to disable auto-update for this app.
[MTCD Android Head Units General] giant53:
On your radio go to playstore with your account to this app and disable auto update for this one.
[MTCD Android Head Units General] Tigrowski:
Thank you @marjanoos @giant53 but can you tell me where exactly do I block the updates? I've gone to the Play Store -> my avatar -> apps and selected WebView here a million times, seem to have examined every pixel of the screen but I still don't see any "disable updates" toggle anywhere :/
[MTCD Android Head Units General] giant53:
I'm sorry, I see now that Webview is a system app with no option to block updates.

But why do you have to uninstall the updated versions?
[MTCD Android Head Units General] Tigrowski:
Ohh, I see, that's why I could not find the option anymore :( I need to constantly uninstall the updates because otherwise I'm getting random "WebView stopped" error prompts from the system which I constantly need to close + various apps and google services stop functioning until I do :(

Try a search on Google: "disable updates in Android" Maybe you find something...

I am also having the same bluetooth problems where the last connected phone is the only one that auto connects. I have a Px5 HA2_rk3368_9.0_ota(20190731) MCU MTCE_HA_V3.30_1.

Did you find any solution to this? I have a PX5 running Android 8 and had major bluetooth issues and upgrading MCU to 3.14 fixed that.
[MTCD Android Head Units General] Tigrowski:
No dice sadly :/ Anybody has any more ideas on whether it's even possible to block the WebView updates anymore?
[MTCD Android Head Units General] Pavel-71:
I don't have this problem, but I was wondering how it is. Indeed, webview has disappeared from google play, and in addition, they arbitrarily set automatic updates. The only thing you can try is to turn off automatic updates in your account, but in this case you will have to update other apps manually. Google play/ your account (logo in top right)/ Settings/ Automatic app updates/ Don't update apps automatically. Then uninstall webview updates. Ignore webview update requests. Write if it prevents updating the webview. If it didn't help, then try to update it to a firmware that solves this problem, write to the seller about the update, or post the system information here.
[MTCD Android Head Units General] Tigrowski:
Thank you for the suggestions, will try it out!

As for the system info of my unit, here they are:

Mtcd could be upgraded to mtce and I'm pretty sure it's the same for mtce to mtch especially as the version numbers for mtch continue from mtce. But been away from the forum for a few years so not 100%. Will try soon but if you do don't forget to export your mcu configs first.
[MTCD Android Head Units General] Pavel-71:
Citation CS-X (4pda):

You are trying to update the MCU firmware of your MTCE platform radio with firmware from another MTCH platform - although these platforms are closely related from the same developer, they are still different (the MCU microcontrollers are different and the MCU firmware is different), you will be happy when the "update" fails, otherwise, your radio would stop working and you would only be able to restore the MCU with the help of a programmer.
