Go to dasaita.com. there are published all the firmwares for bmw series units
I'm sorry, I have already found, I did not know that the firmware is in the forum section. In that case, the only question about connecting to the power supply will be grateful :)

Thank you for your answer, but when I enter desaita, I only see sales when I enter bmw px3, nothing is found when I enter the firmware, I have no idea where to find the firmware for the bmw px3. she fell into bootloop, she needs to connect to the power supply outside the car and upload the firmware, but when I connect the cables yellow red to plus and gnd to minus, no signal pops up on the screen. I connected other radios to the power supply and there was no problem and here, however I did not connect, no signal pops up

By the record .. i am pretty sure that your unit has a reset pinhole ....by using that you can punt the unit in recovery mode for forcing an update without removing the unit from the dash.
Thank you very much for any help, i.e. if, outside the car, after connecting to 12v, no signal is displayed, there is no need to combine it, just connect it back to the car? I read somewhere to connect outside the car, all you need is a yellow cable to 12v and a black cable to the gnd, but the gps antenna must be connected. Anyway, thank you very much, I really respect all the help and knowledge and I am extremely grateful :)

Może spróbuję ponownie mikrofonu pokładowego. Kilka razy wyłączyłem mikrofon zewnętrzny i pracuję z Iris, aby być może wymienić chip/płytę główną. Nie wiem. Wszystko inne działa dobrze, ale ludzie po prostu mają trudności ze słyszeniem mnie (brzmi jak dużo hałasu w tle, jak mi powiedziano). Nawiasem mówiąc, właśnie zainstalowałem przednią krzywkę (było to bardzo łatwe). Zapłaciłem około 15 USD za aparat i jest to jakość. Na pewno pomaga mi „lepiej” zaparkować ciężarówkę.

Maybe I'll try the on-board mic again. I switched out my external mic a few times and am working with Iris to perhaps replace the chip/mainboard. I dunno. Everything else works well, but people just have a hard time hearing me (sound like a lot of background noise I am told). By the way, I just installed a front cam (it was very easy to do). Paid about $15 for the camera and it is quality. Helps me 'better' park my truck for sure.
I have a radio with "zlink" and the motherboard has a problem with the external microphone. It must be connected on the panel as an internal microphone. I have a second radio without zlink and the internal and external mics work. I tried to advertise without success.

Help a newbie please!​

Totally new to all this. I recently factory reset my Dasaita unit, and did some OTA updates (forgot which ones), and never did any flash drive updates (not sure if I need them?). Now when zlink launches, the android auto interface isn't split screen anymore. I'm already engaged with a back-and-forth email with Dasaita, who said they'll send me a zlink update when ready. Still waiting.

Now android auto looks stretched and wastes screen space. Anyone know what's wrong and how to fix?

You just may need to wait.
I read it's a matter of making android auto recognize I have a widescreen, so now I'm wondering if its somewhere in the settings I can't find, or some code I need to change. Other tutorials online are not for zlink.

And thanks. Was looking for more insight as I like understanding things and if I can help myself as a DIYer, why not?

Dod you have zlink configured to HD? If not go to settings in zlink and scroll down to enable HD

    You have a rare MCU version, I couldn't find MTCE_AW anywhere. You don't need to update the MCU, 3.75 is a fairly new update. Crossing MCU manufacturers is not recommended. You can also update the firmware(rom) from other manufacturers, but no one can guarantee that the Z-link will work. You have to try it yourself. First, try contacting the vendor to see if they have firmware and MCU updates. Z-link can be updated separately but you have to ROOT but it doesn't work very well see the thread below. If everything works for you, leave it as it is, you may cause yourself more problems than now, there have already been many cases where updates have been bricked. Especially Dasaita(HA) has white screen issues after firmware update. It can be fixed, but why add more work.Please read the MTCD threads thoroughly first.
    Z-link:

    Here you will find the firmware of all px6 android 10 manufacturers, including HCT, there are attached screens that you can use to identify your ROM:

    Hello. I have a PX6 1280x720 RK3399 MTCH_HA Dasaita head unit model HA5224 with CB008 running off Vivid 10 on android 10 with latest firmware update 20220518.155842 . Nissan Rogue 2017, I am looking into any info on how to update the unit further. Is it worth updating to Android 11 just want to be further educated. Thank you. I am learning off of research and reading on how to do updates and take advantage of my unit
    If works well don't upgrade. A11 does not include any different feature or enhancement
    1
    Why is everyone wanting to update to A11 I see pretty much anyone running Vivid 10 and Android 10 wanting to upgrade to vivid 11 and Android 11. To get vivid 11 do you need to have android 11?
    Vivid 10 = Vivid running on Android 10. Vivid 11 = the same exact Vivid but on Android 11. You aren't missing anything and Dasaita's Android 11 builds are plagued with Bluetooth issues. Stay on 10

    Yes , but only the Rom....the MCU is better to upgrade only with the AW manufacturer.

    hi, is my head unit compatible with these upgrades ? (PX6) (1024x600).

    I noticed that the MCU in my unit is MTCE_AW and I can't find any files related to this type ... any idea ?
    MTCE_AW is a SYGAV unit to get their latest firmware you will need to email them a screen shot of the about page and they will provide you a download link. They were very responsive to my request for the latest updated firmware (they responded within 24h of my request). My head unit is SYGAV and has MTCE_AW.


    Worth noting that the DASAITA firmware updates will work with your unit but I would recommend getting them from SYGAV in case there might be any compatibility issues.

    Because the upgrade is risky, it might lead to CRASH, BLACK SCREEN, OR SYSTEM ERROR;

    Unless there is a major bug in the car system, it unable to be used normally.
    At this time, you can choose to upgrade the system to solve it.

    contact your dealer to make sure you are choosing the right firmware and right update steps

    @hotaudio

    It would be great if you can share what's on your mind for the future of this device... Would it be updated to 7.0? Are you guys thinking on moving directly to 8.0 as some post suggested? Or are you focusing on further cleaning/bug removal on Android 6 for the foreseeable future?

    While upgrading for the sake of being able to claim compatibility with latest android release is not really helpful for the users (everybody prefers a stable device rather than latest SW), what Google is doing with the assistant seems quite nice :) and I understand there's no possible dirty trick to get Assistant on Android 6 (while there're some "options" posted for Android 7)
