There is also a hardware/software fix.

This one above is not for everyone.

There is a picture around that shows how to tape to deactivate the internal mic. It is also possible to desolder + or - of the mic.

And then use the software volume fix for the mic.

On Toyota it do not work to, but since last update my radio shows Outside Temperatur in the Statusbar from Canbus line.
With BMW the external temperature via canbus is shown by firmware 0328, maybe even before... I don't remember exactly.
In any case, the information from the car to the radio, with canbus, is very few (with BMW) it does not even show fuel consumption, average km, etc.
With the previous Erisin Android 9 "radio I had much more information than the car via canbus .. but Climatic Control never.

ID codes for Climatic Control via canbus is very complicated to interpret, and very different between each brand \ car.. I think that ONLY the Gui for Climatic Control exists in these radios, but it doesn't work for most car brands. German brands (canbus more sophisticated than others) does not work.

The Chinese still have to work A LOT on canbus\radio management!

Hi guys, I'm going to disconnect the internal microphone by blinding the connections 1 and 2. I just want to be sure that it doesn't matter if I do it on the connector as shown in the picture or if I open the unit and do it on the motherboard side. Just to be sure. Thanks for the quick confirmation :)

I desoldered the micro directly from the board and until today everything is perfect

Hi.

Please check this link, https://we.tl/t-BfzaiKcdY0, this is our bootlogo that we place in the units that we install. We provide this service as a extension of our main activity so this is not a publicity or sales promotion, it is only a bootlogo example that I am sharing with @MauriBixio .

The details of the file are:
960 480 20
p 0 0 part0

It is a unique part file with 91 frames that continuous in a endless loop until the end of the boot time.

This unit is a fresh one, so we don't have too much to load but even in the future the logo will continue in the loop until the end of the time.

So depending of you logo you may make a endless loop with:
1280 720 30
p 0 0 part0

and will redo and redo the sequence without any stop.


One aspect.

Sometimes when editing the desc.txt with notepad I realise that the final bootanimation.zip was corrupted and was not updated with success.

I prefer to use wordpad.

In case of doubts do it in Boot Animation Factory to avoid additional bugs in your test process.

best of luck
Hi,
No possibility to ALSO add a sound (very short-lived) to the animated boot?
Have you ever tried?
If possible, in which format (.wav or .mp3 or .ogg or.....) and how to integrate it into the final animation?

Thank you. ;)

Do you know any working app which can be installed in ours HU, and it allow you to set the volume separately to apps. I have something like this in samsung phone, and it call Sound Assistant. But it is only for samsung devices, ant it not work in HU (i was try it). There is also something like AppVolumControler, but it is for older version of android, and it also not work for us.
In head unit, no. Only on phone (media source)

There should however be a hidden setting in the HU to lower bluetooth input gain, since this is forced by the bluetooth audio standards, but i do not think JITU has bothered to allow for configuration of it.

Also, the android auto absolute-volume setting overrides all other bluetooth gain settings since it routes the media signal over wifi or cable instead of bluetooth. A better description of this here: https://www.reddit.com/r/AndroidAuto/comments/mcwb49

Sorry but i have this off since the beginning. I was also try to switch to Carplay, but no results.
As for now, only thing what worked to me, was to shut down AA app manually, direct in my phone.

i'm looking for the possibility to app volume control, because stock radio is too quiet compared to the rest. I set google maps to quiet mode, and it still to loud when working with radio in the same time. Also the same with stock music player or any other like musicolet, ect.

Ah. IIRC Renault uses very low power radios, and therefore have speakers that respond VERY easily to current, ergo will be VERY loud with a proper amplifier that the S-class units have. Default is something like 4x20w and you are now feeding them 4x45w from the TDA7388 amplifier built into the stereo.

I highly suggest you replace the trash speakers that are stock in your renault, and that should solve every other problem aswell. Even a basic €40 kit will be a massive upgrade in sound quality, but do make sure they fit both width and depth-wise.
don't want to investigate anymore....
I tried to use some software to low down the volume again, but failed, nothing changed...

Uninstall android auto then? Iirc its elective not system bundled, so you should be able to just uninstall the package from your phone.

Only way to find out is to hook up a multimeter and measure peak AC voltage at volume setting 1, going into speakers at the door speaker connector.

Also, using what software?

Hello everyone, please tell me if it is possible to install magisc on this device to install Moto Dolby Audio / Audio FX Port or Dolby Atmos Port
OnePlus 8 or ViperFX. The fact is that when I connect my smartphone via bluetooth (there is root access and Moto Dolby Audio), the sound becomes much better and louder, and I would like to be able to do this without connecting my phone. maybe there are some other ways (without magisk) to install these AudioFx please tell me

Hi,

I din´t try it until now, in Boot animation factory we have an sound option that ask for a mp3 or wav sound.

So it may work.

If I find some free time I will make some tests.

    So in the end, we worked out with the seller that the BT chip is a bit cheap and allows the connection of only one device at a time - be it an OBD or a phone.
    Furthermore, autoconnect already works with my HU, because from my point of view the buttons are named illogically - when the button says "close" then autoconnect works...

    It seeems that we are all Beta Testers 🙃
    With my S8 (native all QF01) I can have both BT the phone and the OBD interface paired and connected together, without problems, so the seller did not tell you the truth, because Chinese seller of these units, whether Hizpo or Ossuret, does not They know it thoroughly, as they are NOT the real producers but only sellers.
    Hizpo (I know them) have technicians who answer questions in a generic way, without real effective knowledge of both SW and HW of what they sell.

    I am writing an answer to my question dedicated to specialists of this topic who do not know how the device works, but only write their guesses, and they confidently think that everyone is stupid!
    Changing the MCU version QF01 to the QF03 version is possible and very easy! Changing the version did not negatively affect my system in any way! The screen did not turn on from time to time and the seller himself told me to change the MCU, sent this version and told me how.
    To change the version of QF01 to QF03, you need to enter the code 774411 in the factory settings and then download a new MCU. The board version has nothing to do with the MCU ! As I understand it, there will be no more MCU 01 version

    Some features are better on Teyes than Sx.
    The CPUs are not the same, either.

    UI: they are all similar, true, but the graphics of a UI are subjective, I don't like the UIs of both Sx and Teyes, for example.

    A real IMPORTANT point for me is the display, in particular its sharpness, brightness and anti-glare, lasts the day, with direct sun.

    Well, with my S8 8GB\128GB as I have written here several times it is VERY BAD, very low brightness, during the day at 100% almost not readable what is running underneath. Anti-glare film does not exist...

    IF Teyes CC3 2K instead has a better screen, which you can see perfectly during the day, for me it would already be a great thing, even if it costs more than Sx units, but the problem...is all this true or does Teyes just want to advertise\marketing ?

    Anyone who sells advertises their product for sale even more than reality, to sell it...

    ONLY someone who has purchased and uses the latest Teyes CC3 2K units could truly say that!
    Now i'm waiting for cc3 2k, so when it comes, i'll say some more, compare to s8 unit which i use since february

    I have a QF03 never had a single issue with it. Have updated to latest firmware and have done 1 mcu update (1 more available not sure if I will install)
    Of course, MANY problems also arise from poor writing of the latest firmware and MCUs released by developers.

    My advice:
    If you have the unit that works well, don't chase constantly new firmware and MCUs, leave the working one as it is.

    Hello,
    I have this headunit in the variant S5:
    https://a.aliexpress.com/_mNPpRPg

    It is working fine, but after turning it on the first time the screen went black after five to ten minutes. After turning it off for seconds and turning it back on the screen works fine for a few seconds but then it turns black again.

    The radiator on the back is connected to power so heat shouldn't a problem. When the screen is turned black audio is still working fine and all the my steering wheel controls are working.
    Also the touchscreen is working as well as the buttons on the left side of the display.

    After using it for a few rides (3*20ish km) the sreen turned white 5 minutes after it turned black. Then again it turned black but had some weird grey stripes. These stripes were also visible even after a car stop, whilst i was seeing the home screen.

    Is this a already known issue or did a catch a faulty device?

    The seller was sending me this link after i contacted him about the problem:
    The system firmware link: https://jitu2fixgreenscreen.oss-eu-central-1.aliyuncs.com/update.zip

    A video showing my problem:
    Don't listen to this nonsense about the MCU! I have exactly the same version, upgraded from 01, the seller himself told me and told me how to do it! Everything works well and there are absolutely no problems related to the MCU! I will tell you more that as I understand it, absolutely all new devices work on version 03, and version 01 is no longer supported! The seller himself explained to me that version 03 is an updated version 01. I will tell you that 100% you need to look for a solution to the problem only with the seller! For example, in my case, the seller directly solves problems with the manufacturer and gives me answers the next day. In the same group, since the appearance of version 03, they say that it cannot be installed on 01, they say the board is not the same... In fact, it is very easy to install and the board is the same!
    I write rudely on this issue, because people who write false information based on their guesses are annoying, and when you criticize them, they turn your message into spam!
    NEVER REARRANGE THE MCU ONLY AT WILL! THIS CAN TURN YOUR DEVICE INTO A BRICK, THERE ARE ALREADY A COUPLE OF SUCH CASES IN THIS BRANCH! MAKE SURE 100% THAT THE MCU SUITS YOU, ASK THE SELLER AGAIN, THEN CHANGE IT! IF YOUR DEVICE WORKS PROPERLY, YOU DON'T NEED TO CHANGE THE MCU, JUST THE FIRMWARE!
    Look for the answer from the seller!

    Hello all,

    it seems that there are some QF001 owners out there but not much informations. So i will try to collect everything and put it at one place.

    The original manufactor is shenzhen jitu technology co. ltd.

    These units are sold from Ossuret, Hizpo and other brands. This are the sellers specs:
    specs.JPG


    The Android 12 is fake which is Android 10 in reality.

    I have the 8/128GB Version myself:
    Screenshot_20221129-085346.png


    Codes for the factory settings menu:

    Different firmware versions are inside this thread. Take care of the right MCU file and beware that clear user data is enabled by default on update. There is also a dedicated firmware thread: https://forum.xda-developers.com/t/...s-with-uis-7862a-7862s-not-fyt-based.4541261/

    Dedicated thread for gaining recovery access: https://forum.xda-developers.com/t/...uret-s4-s8-uis-7862-headunits-no-fyt.4538107/

    Beside the faked Android 12 Version the head unit seems to be a good bang for the buck. I´ve paid around 230 Euros including VAT and shipping. The unit runs stable and powerful so far. Everything works as expected. The Android is a bit downcutted by the manufactor. There are no text notifications in the statusbar e.g. But i can compensate that with widgets.

    Against the description android auto works wireless with my Xiaomi Mi10t pro. So that's also nice to have.

    Tweaks, mods and others:
    - my wire harness was labeled wrong. Key 2 and Key GND were swapped. So better check the cables before connecting. For me the correct wire names/functions were in the printed manual.

    - replacement fan that fits my model: Sunon MF35101V21000UA99

    - there's a sleep whitelist in the factory settings menu that prevents apps from being killed in standby mode (ignition off). That's very useful. I've whitelisted Google maps e.g. and don't lose my programmed route anymore if i turn off the engine for a short stop.

    - tasker trigger for warm boot: detect any USB device connected. (You have to plug in something into the usb port, dashcam or pendrive e.g.)

    - the status bar only shows a few symbols and no text notifications. Therefore I use a notification widget in combination with nova launcher. This way I can see all notifications in a widget which would be at the status bar originally.

    - wireless ADB is enabled by default with root user. 🎉 The port is 9876. ( I've found that inside the build.prop)

    - if you want to have a look inside the firmware you can use a rom kitchen tool like CBR

    - how to change the boot logo:
    1. If your player is 1280*720 screen, you need to rotate the picture 90 degree, and cut it into 720*1280 size, transform the picture to .BMP format.
    2. If your player is 1024*600 screen, you need to cut the picture to 1024*600 size, transform the picture to .BMP format.
    3. copy the picture into your Udisk root path, and then connect Udisk to the player. follow the steps settings-factory-8888-Logo set-then you can see your picture and select it- click update logo.
    - how to change boot animation: https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88086835

    - enhance the microphone and call quality by using the external microphone and disable the internal microphone by masking two pins of a ribbon cable. It's explained inside this thread (link to post will follow)

    - GPS tweak: https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88112693

    Known issues:
    - "hey Google" (activate the assistant by hotword) doesn't work
    - no car speed dependent volume control (manufacturer says it would be implemented later)
    - the firmware is a debug release which is a serious security risk (every app or malware can get root access through ADB shell). On the upside you can also get root access through ADB and do everything you want

    To be continued...

    Cheers

    Hi all, if anybody would like to test a very early alpha version of NavRadio(basic), they can find it here:
    Download NavRadio BASIC for QF01

    it's incomplete, full of bugs, it surely crash here and there but still usable.
    I have enabled Google Crashlytics to help me debug all the crash and ANR so more people use it and more i'll fix it.

    The full version will come when the free version will run smootly.
    Enjoy;)


    NOTES:

    - Autoscan is done by MCU and it's fixed to 18 stations. Anyway you can use Autoseek function to find more stations or add new ones to the existing ones.
    - The first frequency at startup need to be fixed.
    - Sometimes you can hear the sound muting for a second, it's because the ROCO service think that navradio is a player and not a radio. I'll look for a fix later on..

    And now a few more!

    1122 / 2211 - both popup a bubble with chinese text. I thought they were the same at first but they have different characters. (They both have the word “log” in it)

    6655 - opens up a screen that appears to be the same as 555666 but these are also in Chinese so I don’t know if there are differences. Notably when you enter this menu with either code it will record a snippet of audio from the mic and play it back.

    4455 - engineer mode (lots of stuff in here to explore, includes adb shell)

    5544 - gps stuff

    1212 - notification that says “slog copied to unkown”

    2121 - seems to just take you home

    45645600 - download mcu file

    How did you discover the codes?
    Just by trying a bunch of different codes and looking for patterns. Starting by looking at the codes we already knew I discovered they are all a repeating sequence of digits that are adjacent to each other on the keypad. Once you find a pattern there’s usually another code that uses the same pattern somewhere else on the keypad. If you actually type in the codes and look at the physical pattern they make you’ll see what I mean. For example 114477 is just the digits in the left column of the keypad going down. 336699 is the same pattern in the right column. And then some codes are just variations on top of that, like doing a code in reverse (which we already knew) as well as adding 00 to the end of some. This is how I discovered all the codes. Once I’d find one code Id try that same pattern in all places and variations. Simple as that! I’m sure there’s more patterns yet to be discovered so try different ideas out and see what you can find. With many people using these strategies I’m sure we can discover more! I may have even missed a few using the patterns of ones I found.

    For whom that's interested and is annoyed that display time is out of sync with atomic network clock time.

    Myself don't use 4G network, but WIFI hotspot from phone.

    Each time when I opened the GPS test app, time changed and was out of sync by 2 to 4 minutes, also when I forgot to put hotspot on my phone on, after that it was taken the GPS time sync by default after startup,
    So first taken my right hotspot network time and changed 30 seconds later to the out of sync GPS time, it was also out of sync with my OEM Opel board computer display.
    With some hassle I could changed that back but needed to be sure that hotspot was always on before starting the car.

    Think I found a solution.

    Note, I don't use sleep mode, always have a fresh cold start, unit starts up with firmware date and time, 09-01-2023, 12:05:54.

    After going in the factory 5544 GPS setting, changed on first tab screen "agps" the server SUPL host to supl.google.com, changed port to 7276 (seems secure port), but you also can leave it on 7275, then tab screen "information", on the bottom page changed the satellites to GPS, Glonass, Galileo, my problem disappeared.

    My unit correctly shows the time now, after a start-up it is in sync within 1 second compared to atomic clock, with or without hotspot, mean also without network connection it syncs with GPS satellites the time correct.
    The AGPS SUPL was using the Chinese host (supl.qxwz.com) and preferred what it looks some Chinese satellites for Glonass and Galileo and somehow the Chinese GPS time is inaccurate.

    Rather Google then the Chinese that follows me ;)
