I see 👍, problem for me was that sim card / 4g was not working..

Solution was to get new , different screen.

In order to get the new screen working, it also needed new "screen firmware".

So if screen is changed, just be aware that it may also need update, other from the usual headunit firmware and MCU update.

Now that the basic connections are up and running, time for some customization... first of all, I'd like to switch to a different radio app, is NavRadio+ (which is one of the best choices from what I've read) compatible with my S8?

I'd also like to switch to a different music player because the folder management of the default app is a nightmare; several people here use Musicolet, but looking at the Playstore I've read that this app app can organise and play only the local audio files which are stored on the internal storage or SD card. Does this mean that the app does not work with usb sticks?
[Android Head-Units] MasterOfLight:
yes, it is ! works fine for me ;-)
[Android Head-Units] Pingone:
My guess: would it be possible that the newest S8 boards are not affected by the sim problem?

As anybody used a screen protector with the S8?

I wasn't able to connect to 5Ghz over hotspot. Had to put it on 2,4 Ghz on my phone and then the unit found/saw the hotspot and would connect.

Yesterday I found this info while looking for the Ford issues:

Android head unit not connecting to hotspot.

The android headunit won't connect to the hot spot - some suggestions on how to fix the no data problem from a hotspot not working.

android-headunits.com

and further googling gave me info it has to do with 4G/5G capability of the phone but I can't tell if this is correct.

Maybe I could try changing security for the hotspot, didn't try that yet
[Android Head-Units] Clyde72:
I didn't even know 5.8 Ghz wifi was called 5G also... learning every day, my phone is 4G and 5Ghz band over hotspot didn't work. 5G cellular is only available in big city centers here so I don't bother buying stuff that is 5G capable.

5G cellular is Belgian marketing too, there was a long big fuss & debates about the licences (the belgian way, we have not enough politicians I guess 🫣).

This is a King Ranch with Premium Sony THX sound package using a type A bezel (all square openings) and the single board switch panel that controls all of the stock radio functions including On/Off, CD, Tune, Search etc are CANBUS. The stock radio has on a CD opening on it and no other controls with a separate LCD display using a BMW video cable from the stock radio. Fairly certain that even on lower trim levels, that the single board switch panels in the bezel are canbus but?? No matter what unit I choose, I will need to solve the wiring problem and interface the F port on the HU to the vehicle CANBUS. Reading in the Ford forums they reference that the BCM signals the HU and the amps for On/Off but no details. No help searching for wiring specific on a Clarion UQW1318 or FORD BL3T-19C15-(xx). Looking for love in all the wrong places :-( ??

I really hope that this will make it right since it has the F port wiring from the decoder

[Android Head-Units] Clyde72:
That indeed makes things confusing...
[Android Head-Units] Clyde72:
That's real lame if you will have to spend another 50€ for it to work in your car...
[Android Head-Units] AlphaRadioDog:
I am asking the seller to supply it or I will ask for a $40 credit and see what happens.
[Android Head-Units] Clyde72:
That crossed my mind, maybe involve ebay support to mediate... Worked for me on another occassion with an Asian seller
[Android Head-Units] AlphaRadioDog:
Clyde72, may I ask how you determined that my unit is a (Hizpo?) S5? There is nothing on the package or in the ad saying who or what it is. I used Android Assistant to read the HW and then searched for manu> ROCO model> K709 which lead me here. It does say that it is Android 12 and all of the other advertised specs match.
[Android Head-Units] nyp42:
It says so in the item specifics of the E-bay listing you linked. ROCO K706 is the processor family. If you go to Car Settings -> About Device you will see the system version. QF001 is the device name and the rest of the numbers are the firmware version. The line below show MCU version. There are updates for both being posted here as users get them from the vendor.

If it didn't say so in the listing you would need to cross reference the amount ram/rom memory and the CPU and/or DSP type with this chart to figure it out.
[Android Head-Units] Clyde72:
I looked closely at all the info in the link that you provided and all things seemed to match with model S5. Still a guess in fact :p (look in the upper right corner of the first image, gave some direction...). Also all the sales pitch showing functionality and tech details is similar to Ossuret's presentation e.g.

It is manufactured by Jitu Tech and sold by Ossuret & Hizpo and possibly others. As for the Android 12 install HW info app and be in for a little surprise... or see the first posts with screenshots by blue_one and me (S8 & S4).

Has anyone found a solution regarding the microphone quality? I connected the external microphone, but making a phone call the quality is extremely poor or trying to use it with CarPlay to give Siri commands. They offered to send another microphone but I feel like it is some kind of software issue that is common with these head units.
[Android Head-Units] popamor:
My issue is a little different. I did not attach the mic as I thought the built in mic would be sufficient. But the fan spinning and whining, the voice call on the other party is terrible. I am about to breakdown and pull out the fan.
[Android Head-Units] blue_one:
Can you give me more details please? I only know that the FYT units load firmware updates on boot up.
[Android Head-Units] Clyde72:
The 1126 & 0104 major update both come with "auto_update.zip" file sitting in an QF folder and the procedure given is to copy QF folder in root of an Udisk and boot the device for it to update. So maybe it could be used to revive units stuck after manual updating gone bad at least.
[Android Head-Units] Clyde72:
The mic not working ok when using Carplay or Android Auto seems common with several android HU. Look for the release notes from major update 0104 posted by blue_one, I think the issue can be fixed by updating...
[Android Head-Units] Clyde72:
Did some additional testing with wifi hotpot yesterday. Every last thing running Android or some other linux in my house connects to the wifi hotspot/phone, the gizmo's being dual band capable even on both 2,4 Ghz and 5 Ghz. Must be a flaw with the HU's wifi. I will do some searching/digging for those secret Android wifi settings...
[Android Head-Units] Aaantonn:
I installed the latest update and MCU, I think it works together, I saw several obvious changes.

1. Music control has become softer. Previously, on 1 it was quiet and inaudible, but on 2 it was immediately loud. Now you can turn on the music quietly, this is a big +. The music began to play a little quieter, I used to turn it on at maximum at 16, now it’s 20-21, but it’s not scary, since the speakers still can’t handle up to 30) This doesn’t apply to the radio, the sound on the radio initially worked softly.

2. By entering code 55551 and rebooting the system, the screen really became brighter, in light areas it became whiter, since in earlier versions of the firmware I had to set the brightness to 80%. But one day while working, the brightness returned back, this is noticeable, the screen is yellowish in the white spots, after a reboot the brightness was restored.

3. Dual Bluetooth works after entering the code, a new Bluetooth line has been added to the detailed menu of the system, but I don’t know what to do with it and what it is for)) Previously, my phone and OBD worked simultaneously without problems via Bluetooth.

But there are also negative comments. I used the launcher with a yellow car, changed the settings to a black theme and a white car. These settings have been removed... Now it is impossible to enable the yellow theme and the white car... The launcher also does not work correctly, in the window where the car was drawn the map was always turned on, but now this is not the case. I tried everything to get the card back in place, but to no avail.

Secondly, the radio unfortunately froze once, but I found information that this is not a breakdown, but the norm for Android, which the developers cannot help with now. To do this, they made a reset button that shorts the processor legs, and the radio reboots emergencyly. But for me, this button is installed poorly and it is impossible to press!!! I had to remove the terminal from the battery! I'll remove the radio and put the button in place.)
[Android Head-Units] noyce:
Where do you enter this code? I still couldn't find out...
[Android Head-Units] Aaantonn:
Before entering the factory settings, you need to enter a code, instead of code 8888, enter the code you need and click OK. Then reboot the system. I see changes, since before my screen had a yellow tint, it may not be brighter, but the yellow tint is gone.
[Android Head-Units] noyce:
I tried that and nothing happened. I can't see any difference. Mhmm...
[Android Head-Units] MauriBixio:
It's probably the opposite, that is, I purchased the S8 in January 2023 (all native QF01) and I've never had black screen problems (although I don't use a SIM slot, but a wi-fi hot spot for the network). many with new mainboasrd QF03 have problems with black screen, resulting from sim slots...
[Android Head-Units] MauriBixio:
Me too, type this code 55551 in:

system factory osk /ok

no brightness change greater of 10%. (already use 100% setting)

My opinion:

They have NOT done anything to increase the brightness (October update) compared to the previous ones, everything remains dim...
[Android Head-Units] Pingone:
Yep, my bad, I mean oldest, not newest.
[Android Head-Units] Pingone:
So, overall, no significant/useful improvements and a couple of issues. Think I'll stay where I am...
[Android Head-Units] Barykelo:
I have a black screen even though I don't have the SIM connector plugged in! QF03
[Android Head-Units] MauriBixio:
I think these MB QF03 are more defective than the previous QF01... with my S8 native all QF01 never had a black screen.

The sim slot cut or not connected I DO NOT think it can solve the real problem, which is probably hardware of the MB QF03, and they don't know how to solve it yet.
[Android Head-Units] noyce:
Maybe a stupid question: Is it possible to change graphics such as the car image on Homescreen of Ossuret S8?
[Android Head-Units] Aaantonn:
A new radio is purchased to listen to music, and changes in sound are a serious change. For the first time in almost a year, the problem was fixed.
[Android Head-Units] Aaantonn:
Perhaps it all depends on the screen, my screen was initially declared as super bright and was more expensive. But as Marioti said, black colors are not black, but that doesn't bother me.
[Android Head-Units] Aaantonn:
Yes, change the launcher.

[Android Head-Units] Pingone:
Well, good for you, of course. If you mean volume control improvement I can live with the actual setup (which BTW does not bother me: maybe different hw/motherboard?) while the other issues you talk of might be a problem for me. Just personal preferences :)
[Android Head-Units] Aaantonn:
System updates are not released to make you like something, but to fix problems. You probably won’t even notice those problems that are being fixed, but they are there because the firmware is all raw. So, the overheating of the processor was corrected earlier, you would not have noticed the overheating until the processor went into protection, and the sound settings menu has also changed 3 times over the entire period, as well as the sound itself, which previously gave an awful lot of bass, and this is super important for me if you don't care about sound quality, then what to talk about. Many people complained that the screen went out and the problem was not in the screen. I think those who have been using radios for a long time know all the shortcomings and how important updates are. Therefore, I consider updating the system mandatory.
[Android Head-Units] Pingone:
If I experimented issues I would surely consider the risk of updating (yep, speaking of "experience", my 35 years experience in electronics and software says that system updates are often risky, especially when released by not-so-well-known entities). Since I'm not in that position at the moment and have nothing to fix because nothing is broken (and I'm pretty sure about that), I'll pass.
[Android Head-Units] noyce:
I meant If it's possible to replace the Image with own image.

Also I'm experiencing another Problem after the update to the latest firmware. Before the update the Speedometer was replaced by TomTom Go Navigation if the app was running in the background. Now that doesn't happen anymore. Is it a bug or possible to change somewhere in the settings?
[Android Head-Units] Pingone:
I'd like to to switch from the default apps for radio and music to something more functional such as NavRadio+ and Musicolet. Are there better alternatives? A word of advice from the most experienced members would be great.
[Android Head-Units] MauriBixio:
Changing the car image in the OEM launchers: NO possible.
[Android Head-Units] marioti:
you can't change the default apps in main screen preview. (except navigation). But you can change the launcher like Nova or Carwebguru, etc., and there you can do all
[Android Head-Units] MauriBixio:
I use CarLauncher Pro app as launcher, I designed my own theme for it, and it works perfectly. ;)

I have never liked the Sx units oem launchers and their graphics cannot be changed!
[Android Head-Units] noyce:
Anybody else having the problem that navigation isn't showing on the homescreen instead of speedometer after updating the firmware to latest version? How to fix that?

I tried a factory reset but it's still not working and now I have another bug: Button lights don't work anymore. Will try to downgrade firmware tomorrow to 20230614...
[Android Head-Units] Aaantonn:
Yes, I wrote about this above, the navigator does not turn on where it should, apparently we use the same launcher) The launcher can be downloaded from the Internet and installed as a working one, it’s easy. But otherwise I like everything. Try turning on the buttons again in the settings menu via 8888, it is unlikely that this is the fault of the bug.
[Android Head-Units] noyce:
Your answer came too late... I already went back to the old Firmware. Now touch panel isn't working anymore and calibration isn't possible because the calibration points on the left side of the display can't be recognized. I tried factory reset with help of usb mouse but that didn't help. also tried to go back from the QF003 to QF001 mcu but that also didn't work. It says it's the wrong mcu for my system. Is there a way to fix my HU or did I brick my device 😞
[Android Head-Units] Aaantonn:
Downgrading the firmware without first downgrading the MCU is not a good idea since the MCU is responsible for the operation of the hardware. Try first removing the power terminal from the battery and rebooting. To replace the MCU, you need to enter a code.

It’s better to initially try to return the new version of the firmware, only at the beginning, before installation, check the second box, where mine was unchecked! The system may return to factory settings.
[Android Head-Units] noyce:
Tried that already (remove power cable). Will try to replace the mcu with this code you mentioned.

OK, I'll try it this way. Check which box?
[Android Head-Units] Aaantonn:
I have the first item checked, uncheck the box and check the second item, it will say delete all data. This window will appear when you reinstall the system.
[Android Head-Units] Aaantonn:
Apparently the new MCU was responsible for the operation of the touchscreen with the new firmware, you downgraded the firmware version and now the MCU does not work correctly, since it is stated that this firmware version affects the operation of the screen, but probably only with the replacement of the MCU
[Android Head-Units] Aaantonn:
Have you removed the power terminal from the battery?
[Android Head-Units] noyce:
I'll try that tomorrow. Have to get some sleep now. Thanks!
[Android Head-Units] noyce:
Just reinstalled the old mcu again with code. But still I'm not able to calibrate touchscreen because it doesn't recognize touches on the left side of the screen. Again reinstalling the old firmware with deleting all settings didn't help. 😔
[Android Head-Units] marioti:
After installation just reebot system. In my case always work and touch button work again
[Android Head-Units] noyce:
Another factory reset with code and one more reboot did the trick. Everything works again 😊
[Android Head-Units] Aaantonn:
Don’t be afraid to install new firmware, the main thing is to double-check everything 10 times. On the last three versions of the firmware, the AI assistant stopped working for me, and now the map in the launcher does not turn on in the place where it shows the speed. But this is small compared to what has changed over time. We improved the sound several times, changed the sound settings menu twice, the sound card began to work correctly (after all, the radio was bought for the sound), the main menu changed. A car battery charge indicator has appeared, the Chinese language has been removed from the door opening window, now when you make a call it shows who is calling. Those who write that they like everything anyway didn’t see the first menu; I didn’t have 20% of the settings in it. We worked on the cooling, in my case the screen became brighter, and much more. The updates seem small at first glance, but if you compare the year before and now, these are two different systems) Also, I don’t believe that the manufacturer does not check the firmware, this is nonsense. And just in case, I have all the firmware versions stored, even the seller sent me the very first one)
[Android Head-Units] noyce:
I would go for October Firmware again because other than the Speedometer/Navigation issue in homescreen everything was ok. But to have that working is essentially for me. So if there's a workaround, let me know! You wrote something about the OEM Launcher can be downloaded from somewhere on the Internet. Where did you find it and how to install it if that fixes the Speedometer/Navigation on Homescreen bug?
[Android Head-Units] marioti:
I have this firmware and no issue with navigation on homescreen. Do you turn off the pop-up window map? You have to go to settings, all aps, find the google maps, and turn off this
[Android Head-Units] Aaantonn:
I disabled it there, this button enabled navigation when the radio was rebooted. They have reduced the functionality of the launcher; previously you could select 4 themes with different colors, but now you can’t. There may be another solution to the problem, but I haven't found it. You may be using another launcher, but it doesn’t have this problem.

I was looking for a solution to the problem and found information that on the Teyes radio, if you want to open the full functionality of the launcher, you must buy the paid version from Teyes, it shows how to do this. Perhaps they want to do the same thing here, or perhaps something just went wrong)

In any case, the launcher can be downloaded for free from the PlayMarket or found on the Internet.
[Android Head-Units] noyce:
Not using Google Maps. I have TomTom Go App.
[Android Head-Units] marioti:
no matter. do the same for TomTom, and also set it as default nav app, if you didn't do this already
[Android Head-Units] marioti:
Well.. i looked there and it sems to all the stock launchers are the same. Right now i use this one

About Teyes, i haven't heard about any payed version of original Teyes sotfware. But there is the payed software (10$ for now) from user gordgelin. He call this soft. VincentVega edition. And i have it in my CC3. So everything i told about this unit, it was on moded soft already.

Hi there,

one (probably silly) question about the interface and the default home page. I just installed Musicolet and I'd like to use it as the default music player, but in the home page the highlighted window in the picture shows the music played by the default player: is there a way to make this window show the music played by Musicolet?
[Android Head-Units] Aaantonn:
Two days later, the launchers started working on their own and all settings were restored) I don’t know why it took so long. The video answers your question on how to change the color of the car, I don’t know if there are such settings in all launchers, and the second is how to enable navigation in the speedometer window. Previously it was turned on from any button, but now only in the second menu item.
[Android Head-Units] marioti:
the same question was coupple posts ago. No you can't on stock launcher. Only if you install a custom like nova launcher, etc.
[Android Head-Units] noyce:
Thanks. Maybe I'll give it a try.

But my question wasn't to change the colour of the car but replace the car image with my own car. If I understood correctly that's not possible. For other HU's this seems to be possible but it seems on our units we don't have that kind of access to the underlying system.
[Android Head-Units] Aaantonn:
All you have to do is download a launcher where there is such a function, you need to search on the Internet.
