thank you, I will try when i am at home!

Unfortunately, my wireless android car does not work either. It randomly stopped working on the 0414 update. That's why I updated to the 08/05 version, that didn't solve the problem either. And even after a factory reset I can't get it to work..
Maybe we should try out downgrading the Android Auto App on our phone then.
What if it stopped working after a Google Play Store update?

I don't think it's an issue on the phone. Normally, with carletter, the Bluetooth logo turns green when my phone has a Bluetooth connection with the unit. That is not happening at all now. The strange thing is that apple carplay wireless just works properly.

Didn’t worked for me.. I’ve downgraded to the same version but still overheating.. what is the normal temperature of the unit ? I mean when listening to radio or using CarPlay ?
If fixed in car, i had 55-65, but in last tuesday i did some mod and
Next change i made. I have glovebox with wentilation (if the ac is working then i have cool air in there) so i connected air tubes and guide one to the back of HU, near the fan. Also i change a air direction, to fan blow inside HU. First tests look good obviously. Before this change, the HU fan blowed constantly and normal thing was 55-65 degree in CPU (condiotions: radio and google maps was on, nothing else, outside temp 22-23 C, AC off, car fan on, on the lowest speed, inside temp was set to 20C). Now there is ca. 42-46 C in the same conditions.

Anyway. Go to Factory and set "332211" it should be a popup with cpu load and temp (you turn off the window by write again this code) . If the load do not change in time, but it's in max, then there is something wrong with MCU firmware or in mcu itself. But if the load change between min and max, i suspect no thermopad between cpu and housing. Somewhere in the middle of this thread, there is a description how it looks

Remove bluetooth pairing on HU and android auto history from phone, then retry. Else factory restore the head unit, and try again.

You have to remap buttons in the settings!
Go to settings, enter 8888 then you will find a menu there where you can add functions to buttons.
I am working now but I will take pictures when I arrive home if you want.

Did you get the Wireless AA work btw?
It worked well to me before the update but now it only works wired via CarLetter. :(
Yes it works again now!. vias the menu of 8888. I have set all the buttons. Thank you!

I have followed the steps above with no success. Even a factory reset didn't help. When I have time, I'll investigate why it will come. Otherwise I will look for another app/solution

Has anyone pulled the Audio player stock app from the Sx model radio?
Horrible look, I would like to see if it is possible to "modify"...

What can be a valid alternative app to this stock audio player, in anticipation of using Car Launcher Pro as main launcher?

Maybe Musicolet. It also has car mode.

Edit: i was thinking of radioplayer. That one has a car mode.

But Musicolet is a good music player

Thanks.
I know Musicolet good app.
I tried this app on Car Launcher pro (only test for the moment with phone, I want to create my theme first...) and it works fine embedded, in background.

With phone, however, when it connects with Car Launcher, an popup appears at the beginning (if I have the data internet active) then immediately after the popup disappears.

No other free and ad-free player, which works totally embedded, in the background (even at the beginning) with Car Laucher pro?

edit:
I'm talking about audio player app that can work mainly offline ..like Musicolet.

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..
Good thing is, it's work on ours HU :)
As a as a beta tester, first impressions:
1. As you notice, it stop playing randomly, and as for me it stop completely, there is nothing i can do but change a station or reload the app. For now it's a main problem.
2. equalizer button, not work
3. the app is in the same volume level as oem app, and for me they both are to quiet. I have hope to get a volume control in this app (it can be done in app like musicolet, so it isn't impossible, i gues)
4. I have notice, that in oem radio app via canbus shows a station frequency preview on instrument cluster (see the video). Is there a way to do the same here?
5. On instrument cluster station preview i've notice also, that radio app volume shows 1 step lower compared to global volume, eg. if on instruments i see volume 2, in the same time on HU displays volume bar in level 3. Maybe it have something to do with point 3 as above.
6. In full screen the app shows 6 remembered stations (quick selection). Now, if i use a split screen, the app shows 4 buttons, and it's ok. But, if i go back to full screen, then i see only 4 buttons instead 6. See seccond video.

It starts sharing WiFi on wireless mode, isn't it?
Mine does nothing. :(
My phone even crashes after waiting a lot.
Hi There
this happened to me when android auto went from 9.4 to 9.5. After several unsuccessful attempts, because after a few successful connections everything failed again (the bluettooth was connected but the carletter did not detect it), it was only possible to connect via cable. I downgraded the firmware because before everything worked, and guess what?. Anything !!. Then I remembered the several years I spent on the MALAYSK forum and had an epiphany. Never upgrade or downgrade without erasing all data (user included). I know it's really annoying but it has to be (tick checksum and user data). One of the things that alerted me was that without deleting everything, when you change the launcher it duplicates the apps in the application drawer. So now whenever I upgrade or downgrade I delete everything. If you notice the time of the first boot of the device after updating is longer. Now everything works like before including (hey google), which only worked with the wake-up button. Try this because it could very well be the solution to your problem, which was mine too. PEACE

Today just installed a new Hizpo S3 in my wifes car, this is a Qf001 / Qf003 version. This is a lot faster than a older S4 Qf001 version.
Canbus Ac working, other features like hybrid car monitor and keylesgo ( smartkey) are working. Sound is a bit better.

Great news.
With this new HU,
Firmware version?
MCU version?

Can you inquire if MCU QF03 also works with "old" HU Sx and current QF01 MCU latest release?

And...AC works,brand car\model?
Canbus HU hardware: type\name\model?

Didnt tested too much, but I will use it primary in next days.
1. For short time didnt noticed stop in playing.
2. Equalizer button, not work
3.Volume level is good for me.
4. Can bus work for me as on stock app, but it would be better to display station name instead frequency.
5. I have similar problem as marioti described for resizing window.
6. I noticed steering wheel button for changing stations not work.
Anyway thank you very much for this project. 🙂

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

So I did the 332211 code and yes the cpu is fluctuating from 600mhz to 1800mhz that means I have to open the unit to see if there’s no thermopad and put it one if needed

I’ll keep this updated thanks

Hizpo S8, MCU is latest 230207 (https://jitu321077708mcu230207.oss-cn-hangzhou.aliyuncs.com/mcu.bin), radio is TDA7708.
As of No 4., stock audi radio BNS 5.0 was displaying station name but this unit displaying only frequency in radio. But if I open phone, it displays "PHONE" so its capable of displaying text. :)

    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

    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
    9
    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 ;)
