Thanks for your report ;)
Please specify your model, MCU and radio type

1. ok, noted down.
2. I still have to work it
3. ok, noted down.
4. i still have to look at the entire canbus, that will be my last priority
5. NavRadio is not considered a radio app but just a third party app so that could be the reason
6. I'll look at it
Unit: S8, MCU QF01 with firmware 0207,
Soft 0508
Radio TDA7708

Noupe, only frequency 😕
I sent this question to Hizpo today, we will see what they think about it. Is it canbus decoder related or something else.
RDS info on the unit I don't think are related to canbus, but to the radio chip tuner.

TDA7708 is able to display them with HU stock radio app, I display them without problems.

Not sure if you ALSO display RDS info on your original little car display via canbus,indeed maybe it's not possible to have (if I understand correctly you have Audi)...the canbus of these units with German cars (I have BMW) doesn't provide many things ...eg. AC climatic control management and more does not work.

RDS is okey, working on mine also. I was asking of displaying radio station name on instrument cluster on the car, because stock audi radio has that option, but android display only frequency.

Normally all models send to canbus just the frequency as an integer or float value, not text.
Even more if the broadcast to canbus is handled by MCU, there is nothing i can do to change it because I can't modify the MCU code.
Anyway first i'll need to look at the code in the original app to understand how is handled.
We'll see...

frequency, and in my case also number of channel (on which i saved the station), and number of FM/AM.
The channel number is only visible for a while after changing the channel

Video which they sent is useless... It shows only turning on AF and TA, then autoscan...
Yes I have FM band display also, but no channel number... It can be seen on video which I posted earlier.

Is this info sent via canbus from HU?
Firmware and MCU ?
Canbus decoder (of HU) model?

But,if so, probably on Audi (or at least some models\year) it can happen,and therefore better for you!
With BMW it doesn't seem like that...

Hizpo technicians are incompetent...I got tired of communicating with them, they never understand what you're asking (or maybe they pretend not to understand) and in the end they don't know how to solve technical problems.

On the other hand, excellent communication with Hizpo compared to commercial stuff, they ALWAYS respond.

I have yet to try firm. 0508, I still have 0414 (mcu like you of course).
The only thing that differentiates the canbus issue with BMW cars (at least up to firm. 0414):

where you read "CanMcu" version you have the data of the vers. HU hardware canbus, while with BMW I have everything empty... I asked Hizpo the reason, nothing, they can't answer, incompetent technicians as usual!

Maybe this reason makes canbus communication (on some things) not work with BMW.
Does AC Climatic control work with your HU and Audi?
With BMW no,and no info freq. and radio broadcast station (by HU) on the dashboard oem display.

AC controls are shown in popup, and it work good for me. I have Skoda Superb 2012.
In 0207 SW, i hadn't any info about canbus (in system info screen). In 0328 it was "V1.1".
I don't remember how it was in 0414, but in latest SW it show as you see in my pic.
Have you try to reset a canbus model with onternet connection on?

Canbus in my car Audi A3 2009, works for reversing camera, steering wheel controls, and display inside instrument cluster shows some info about HU, if radio is turned on - frequency, if phone, shows phone, aux, media but everyrhing is very minimalistic...
In HU, car settings there is app for canbus settings, maybe you can try to enable a/c, door open or similar it doesnt work on my car, but personaly that not bother me.
I have LZ canbus box, maybe 1.1 version or similar.

Sure...tried everything related to canbus...AC climatic contral doesn't work at all.

Even with previous firmw. and MCU files, same thing, and I've never seen info about vers. canbus on "CanMcu: " summary.

Info is shown correctly in the car-canbus section, see picture (old, with stock HU firmware, no current 0414, but just to understand what I'm talking about.).

Naturally everything else works via canbus... but AC control and radio transmitter info in the oem display on the dashboard don't.

OT:
Do you use Toppal AI?

In HU, car settings there is app for canbus settings, maybe you can try to enable a/c, door open or similar it doesnt work on my car, but personaly that not bother me.
I have LZ canbus box, maybe 1.1 version or similar.
With my car, canbus works for:
auto reverse cam, parking sensors animation (icon with car with colored waves approaching), dynamic steering lines, all buttons on the steering wheel ok, doors open everywhere, show ext. temperature,setup units (C or F) Km or M measurement unit, setup to see in the oem dashboard display the fuel consumption in lt\100km or KM\lt and something else.
It should work (but I don't have) temperature control of the heated seats.

It does not work:
- Nothing inherent AC climatic dual control (for me it would be very important to have this instead) as the HU hides the oem command display (below) and when I have to set the dual control temperatures I can't see the oem display well.
- any info in the oem display on the dashboard (ardio transmitter, etc.) that I could see with the oem BMW radio instead.
- NO infos (directly in the HU) relating to fuel consumption\residual consumption\average speed.

Note:
in the gui of canbus\HU there are also other settings (setup timer for coming and leaving home with the front lights) and more that I don't remember, but I don't want to act on these things, which maybe later ruin the various control units of the car. ..
I also have canbus hardware by LZ and for never auto I have to use this setting... maybe the AC problem here!

For those who have the AC climatic contol WORKING???
- What kind of canbus hardware does it have?
- Model?
- Builder?
- Canbus setting of your car?

Спасибо.
Я знаю хорошее приложение Musicolet.
Я попробовал это приложение на Car Launcher pro (на данный момент протестируйте только с телефоном, я хочу сначала создать свою тему ...), и оно отлично работает в фоновом режиме.

Однако с телефоном, когда он подключается к Car Launcher, в начале появляется всплывающее окно (если у меня активен Интернет для передачи данных), а затем сразу после этого всплывающее окно исчезает.

Нет другого бесплатного и без рекламы проигрывателя, который работает полностью встроенно, в фоновом режиме (даже в начале) с Car Laucher pro?

редактировать:
Я говорю о приложении для аудиоплеера, которое может работать в основном в автономном режиме, например Musicolet.

    Is there any advantage of using Android Auto or CarPlay on the Android HU if all apps you need are installed on HU and the HU has its own sim car with cell service?
    In my opinion there's absolutely NO advantage to use AA/CarPlay if you have 4G SIM with good signal coverage. You only get hotter HU being moooore busy running AA/CarPlay wich will also runs slower and also draining your phone battery for no reason.

    Later Edit: Also I see no advantage to use AA/CarPlay at all on Android HU, even with phone Hotspot is better if you don't have an 4G SIM or good coverage/speed!
    3
    AA only makes sense if you have an OEM multimedia system that is not based on Android. Conversely, with these units, it is of no use, all you need is a phone hotspot (or 4G SIM) and you can use the same apps directly, without AA .

    Naturally my opinion, perhaps not shared by others.

    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.
    2
    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.

    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..
    10
    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 ;)
