It's only 21.8 dB, the Sunon Vapo bearing looks very good for conditions in car.

Cold conditions in car gives condens, Vapo bearing is sealed, oil free and dust proof, long lifespan and can be fitted in every position,my unit hangs in an angle in the dashboard.

It has Maglev technology 😁

My fan that was stock fitted in the HU probably dying because of the cold conditions and humid conditions in this time of the year.

A fan control would also protect our HU better, first warm up before cold humid air goes inside our unit, also thinking about to fit a temperature controller.

So blue_one found a very good fan with a decent price.

thanks @Max643
[Android Head-Units] Aaantonn:
Where does the fan control icon appear, where can I find it? Or is it only on new boards?
[Android Head-Units] Clyde72:
It is an app, can be found among the installed apps
[Android Head-Units] Clyde72:
Thx for the fix, just changed it on my unit and now time & date are immediately showing correct after start up.
[Android Head-Units] Clyde72:
I just installed it on S4, now I'm running latest 0302 fw with 1612 mcu (damn 🙁 but it was an system update for S5-S8 after all).

New apps got installed, Toppal Security & FM Network Radio which seems an internet radio player (though Belgium not avaliable) and once again has to be bought to activate...

I hope it will deliver on Google Maps not crashing... Will have to find out if AF is now working stable on FM... Sound & volume seem to have improved but will have to find out while driving...

Music app does indeed show Track, Artist and Album now making it much more user friendly when using music files on Udisk.

BTW, I also did the GPS fix (hail @Meteordust) and I think it can be beneficial for all of you, much faster location determination and more precise...
[Android Head-Units] Aaantonn:
Tell me what does the fan control application do in the new update? It simply turns on the fan and it blows constantly, and turns it off, or it is possible to adjust the on and off temperature. How does it work? Or perhaps automatically turns on when needed?

Send me an app icon with the name please.

You need to understand whether it is worth updating or not, because after that you need to reinstall all applications, and buy paid ones again! What's the point of changing the firmware once a month.

It is clear if, as in my case, the firmware completely changed the sound of the radio, and if it just added applications that you need to buy, what's the point in that?
[Android Head-Units] Clyde72:
Just today I've updated for the 4th or 5th time and I never lost any user data. Also never had to reactivate one single thing. There is an option in upgrade setttings to prevent the loss of user data... Just have to click it prior to updating 😉. Only 1 time and you're good for all future updating...

It is mentionned in this thread somewhere end of December and beginning of January...
[Android Head-Units] Aaantonn:
You need to look for such a function when I installed the system, I had only to update and clean the system. There was no choice to leave anything. The seller immediately warned that if I change the firmware, then the second time the code for the voice assistant will not be valid.

Might not have needed to be cleaned.

I'll look in the branch for how to save the data, maybe I'll find it.
[Android Head-Units] Clyde72:
I just took a picture where to look for it. Will post it.
[Android Head-Units] Aaantonn:
I see only the firmware itself for the new firmware, which MCU document link should I take? Will mine work from the previous update?
[Android Head-Units] Clyde72:
Was mentionned before but here it goes if you don't want to loose your user data when updating.

Only when an Udisk with the update file(s) is inserted you will find several extra options when going to Settings, System, System Upgrade

1. Option to check(sum) the file, my advice, activate it to be sure - it does check the file for corruption before beginning the update process

2. Deactivate this option if you do not want your user data gone (own apps, paid apps, user settings etc etc) after the update.

These options also apply for manual fw and/or mcu updating...

I was originally on 19102022 fw and 19102022 mcu on my S4, meanwhile on 03022023 fw and 16122022 mcu and never lost any app nor personal settings in the process.

I always update manually, never automatically as this gives me more control. If you find a file update_auto sitting in a QF folder rename the file to update and put it in the root folder of the Udisk and then (system) update manually.

Keep in mind that updating is always at your own risk.
[Android Head-Units] Clyde72:
See the post I just made
[Android Head-Units] Aaantonn:
I'm sorry, but I didn't fully understand, do I need to cancel the check or the second paragraph so as not to lose data ???

And another question, did you unpack the downloaded firmware file?
[Android Head-Units] Aaantonn:
Understood, probably cancel 2)
[Android Head-Units] Clyde72:
Yup, cancel, check the picture
[Android Head-Units] Aaantonn:
When I updated the firmware for the first time, the seller dropped two files to me, this is the firmware and the MCU, and said not to unzip it, but just to throw it on a USB flash drive. And here I see one file called date 😁

Please tell me how did you do
[Android Head-Units] Clyde72:
Yup, unzipped the file, went to look for update_auto.zip, renamed it to update.zip and copied it to Udisk root. Then I did a manual system upgrade on my unit.
[Android Head-Units] Clyde72:
The monthly system updates are only 1 file. This is the February system update...

Read the whole thread from the beginning and you will see there are differences...
[Android Head-Units] Aaantonn:
And what did you do with the update_auto folder, attached a photo, do you need to transfer it to a USB flash drive and change it?
[Android Head-Units] Clyde72:
That is not an folder but an txt file, open it in notepad and it will only show you the version number. It is only information about the zip file. Not needed for updating.
[Android Head-Units] Aaantonn:
Thank you very much!!! Went to update the system))
[Android Head-Units] Clyde72:
Please post a picture here of the system info afterwards
[Android Head-Units] Clyde72:
As for Toppal, maybe contact Toppal directly and explain (& proof) you bought a licence and explain what happened after updating https://toppal.myshopify.com/.
[Android Head-Units] marioti:
one more about the Sunon fan.

Blue one said about MF35101V2-1000U-A99. But in my whole country i find (online ofcourse) only MF35101V1-1000U-A99. Diference is V1 insted V2. Do you think diference is ony a number of revision? and the fan will fit? When i compare their technical data, i see no diference.

Also, is the nevest software (fan app) stearing the fan, or just on-off
[Android Head-Units] Meteordust:
Yes is a difference...V1 is 10000 rpm with 28dBa and V2 is 7500 rpm with 21.8 dBa.

Regarding fan app, this small 2 pin fans need a minimium voltage of 6 or 7 volt to be able to start to run.

I would prefer an on/ off fan because don't want cold humid air blowing in the unit in the cold morning and damage electronics inside, like corrosion and so on, I live in area with temperatures far below zero in winter.

I'm going to put small thermostat behind my unit that just switch the fan on when temperature is above 15 degrees behind the unit.

And this fan app only works with the newest 2023 produced units.
[Android Head-Units] marioti:
Thank you for attached file, now I see all

I have pcb varnish, so I'll put it in to all pcp inside. It prevent by humid damage
[Android Head-Units] Aaantonn:
The application controls, I will attach a photo. It can be automatically turned on at a temperature of 50 degrees, or you can simply turn it on manually. Visually, everything works, but since I still don’t have a fan, the question remains whether it will work on my circuit, they say it doesn’t support it in the branch, we’ll see.
[Android Head-Units] Aaantonn:
Обновление системы прошло успешно, данные системы прикрепляю после. Сделал как вы сказали, все настройки и приложения сохранились! Спасибо! Обновил, так как хотел приложение для управления вентилятором, но оно сразу не открылось, только через два часа при повторном вводе кода 45455656 приложение появилось! Визуально работает, но проверить не могу, пока не приедет вентилятор. Продавец скинул как подключить (вентилятор охлаждения, пожалуйста, смотрите картинку, подключить к синему проводу от жгута RCA.) Прикреплю. Включу вентилятор и проверю! Но все равно радиатора на процессор не хватает.

Второй причиной установки системы было зависание гугла, пока не проверил.

Еще заметил, что приложение CarLetter вызывает частые подвисания системы на несколько секунд, при включении приложения выкидывает из других приложений и, что самое ужасное, отключает вайфай. Каждый раз, когда заводишь машину, все повторяется. Я вообще не знаю, как это приложение используется, я его отключил!
[Android Head-Units] Meteordust:
One more time 😁...yes there is a fan app...but not doing anything with the fan that is fitted with mainboards before 22-12-2022, the unit that we all almost have.

That is clearly described in the release notes you can find in this thread.

With the stock car launchers it is not visable, at least not on my unit.

When you use other launchers like Nova, Agama etc it is visable in app view.

The cable with connector for fan is just a continuous 12 Volt on my unit.

So the fan app seems to be an add-on for the brand new just produced mainboards, that nobody have seen yet.

But If you say that we need blue cable from RCA harness ?, see no picture yet like you mentioned you would attach, we all are curious if they fixed this, with also the older units that you also have.

Hope it helps clearify this.
[Android Head-Units] Clyde72:
Thx, seems like this latest system update doesn't contain mcu.

I noticed your mcu is quite old: 13092022. Latest working mcu for S5-S8 is 03012023 (for S1-S4 it is 16122022). See Firmware thread.

You will have to test for the fan but possible it won't work like with most of us.
[Android Head-Units] Aaantonn:
This MCU was thrown to me by the seller with firmware 23.01.09

According to the habit of the MCU, I found an article. Point 3!

1.MCU is an independent computer, which is made as a separate board, has its own processor, flash memory, as well as programmable inputs/outputs.

2.Android just interacts with the MCU.

3.Attention! As practice shows, it is not necessary to update the microcontroller firmware just like that if the CAN-bus module, steering wheel buttons, Wi-Fi functions, Bluetooth and other options that are important to you are working correctly. Sometimes updating the MCU firmware leads to the inoperability of the device, then you need to contact the service center.

4.The firmware only affects the operation of the controller itself, there is no effect on the Android logic.

5.During the update of the MCU, in no case should the power supply be turned off.

6.The name of the firmware may contain the letter D, which means that the version for a device with a DSP processor designed to process digital signals (often in real time). If you install the firmware for DSP on the radio, where there is no DSP, there will be no sound.

7.MCU firmware has nothing to do with Android firmware. The latter is just the operating system and that's it. Also, when installing the firmware, you need to consider the type of radio module. It can be digital or analog. To find out, you need to look at the data of the installed MCU, tap three times (sometimes you need five) on the MCU version in the device information, if TEF is indicated at the end, it means analog, if Si4 is digital. If you install the version for digital, when you have an analog one, it will not catch the radio (it will constantly hiss).
[Android Head-Units] Meteordust:
Okay...well my unit also have that connector, my unit came with a fan already fitted, can't remember the colour of the cables, have to take unit out.

It seems that yes your supplier showed how it should be fitted, but I'm afraid that is the situation I already have fitted it.

But have to check my connector in the unit and the place of the wires to be 100% sure.

You already showed in picture your mainboard date of june 2022, so I really have deep doubts that your supplier gives you the right info.

Thanks 👍
[Android Head-Units] Clyde72:
We all know what mcu is and does... We know how to Google 😅
[Android Head-Units] Aaantonn:
So why then update it if everything works correctly? My steering wheel is working, the camera turns on, the canbus is fully functional, there is wifi and bluetooth. What's the point?
[Android Head-Units] Meteordust:
Well not everybody Googles 🤣, so appreciate your effort @Aaantonn
[Android Head-Units] Meteordust:
My unit with MCU 0301 and FW 0901 of 2023 works okay now, have no problems at all to update the firnware at the moment...assume Google/ Android security is not updated in this new firmware. And new MCU not available yet.
[Android Head-Units] Clyde72:
Because wondering why they keep on providing new mcu files. Can be the same file every time.

You should eat less sugar with your "What's the point" 😉
[Android Head-Units] Clyde72:
With the latest update Toppal Security gets installed but as you would have guessed... needs activation code... Tsjing tjsing 😉

Special business model. Sell swiss cheese and then charge to plug the holes... 🤔
[Android Head-Units] Meteordust:
🤣 Well developer of firmware probably gets his peace of the cheese also, maybe that's why the holes are there ?, nothing for free in this world.
[Android Head-Units] Aaantonn:
I see this application is in Google, freely available for free, but I still don't understand what it does? How does it protect?
[Android Head-Units] Clyde72:
So true but in all, to me, the unit is worth the money. I enjoy it every car ride.
[Android Head-Units] Meteordust:
Yes indeed....it attracts me too much while driving and not looking at the road 😉

So far so good...now see what the durability will be ..hope for many years ...next week take unit out to fix my fan.

In my search it is indeed hard to get 35x35x10 fan of any brand, Aliexpress has some but in my country also hard to find, but found them, 1 day delivery and had two delivered today , coz minimum order was two 😣, 13 euro a piece.

Could claim new fan at Hizpo, but don't want the same cheap fan that breaks down in a month of using, let's hope Sunon will last longer
[Android Head-Units] Clyde72:
Free to download...

Apparently for road security 🤔. I guess Chinese are really bad drivers or so 🫣
[Android Head-Units] Clyde72:
Looks like you will need to buy an Toppal Security activation code...

No, seriously, in the beginning distracted me also 😉, it took some time to get used to it.
[Android Head-Units] blue_one:
One hint for the fan swap: I didn't use the metal grille for the new fan. It reduces the air flow and makes more noise. You just have to check that nothing blocks the fan at the final installation inside the dashboard.
[Android Head-Units] blue_one:
Added to the first post. Thanks for the info mate.
[Android Head-Units] Meteordust:
Thanks for the tip, regarding metal grill, happily this HU unit is less deep then my stock OEM radio, so lots of space behind it.
[Android Head-Units] Clyde72:
Just had a look and Reichelt sells the Sunun fan. Where you able to use the original bolts? I don't remember.
[Android Head-Units] blue_one:
Yep. It was a 1:1 swap for me.
[Android Head-Units] Clyde72:
Will depend on your car hifi/speaker configuration. Via DSP app you can change the center point/sweet spot with the red dot/ball or select the presets ans then adjust a bit. There are also EQ presets or you can set them manually, set bass boost or not, loudness or not etc etc.

You can play around with it to your taste.
[Android Head-Units] blue_one:
I've updated the first post with some new infos. Let me know if you miss something useful.
[Android Head-Units] Aaantonn:
Hello! Tell me someone had interference when listening to music, namely when turning on the music, it’s all the same from where from the player, radio, telephone, etc., a faint whistle is heard from the right side. You can hear it when the music stops, like some kind of background. It is barely audible, but when you know it starts to annoy! If you press pause, the whistle immediately disappears, it seems that this is some kind of background.

Perhaps this question was in the thread, but I did not find it.
[Android Head-Units] Clyde72:
Not sure if it applies to your background noise but some people needed to remove an resistor, search the thread for "resistor"
[Android Head-Units] Aaantonn:
It seems that this noise gives you a connection to the Internet via a phone via Wi-Fi, I'm looking for all the branches) So far to no avail, but I changed the logo))
[Android Head-Units] marioti:
since couple of days i see here a bit of quiet. So i turn back to my questions.

Does anyone know an app. for fm radio (i'm not searching radio apps working only online) where i can add a staton logo?

Does anyone have an advanced user manual? not just a basic, added to HU.

Just for info. I asked Ossured about new firmware dated 04-02-2023. But they said, the last upgrade they have is 09-01-2023

One more thing. About the fan, maybe it's a good idea to buy V3 version (MF35101V3). It have 5000rpm, so it is a quietetest from all of them. But ofcourse airflow is the lowest to (3,6 CFM insted 6,5 CFM in V2 version)
[Android Head-Units] janolelapin:
Hi,

"NavRadio Plus"
[Android Head-Units] Clyde72:
This thread is the missing advanced user manual... Lots of user info allready to be found since it started.

Ossuret isn't the best or fastest in support, most files come from Hizpo & thx to users sharing them here we can all use them (at own risk).
[Android Head-Units] marioti:
you are right. I was readed this thread from the beginning, and wrote down some interesting things. I thought there is some extended manual. Anyway i plan to make something like that, but i have to spend many more time with my HU :)

Clyde72, what do you wanted to say about fan?

I was trying with free Basic version (without station logo), but the interface is not good to me. Still looking

Aaantonn

couple post ago, you show the pcb with processor. Can you estimate what size is the processor, ant how much space is above it? I'll want to try to fit a radiator with thermostat.
[Android Head-Units] Clyde72:
My fan isn't connected at the moment and I'm in no hurry, still winter here, but as I need lots of electronic components from Reichelt I will order the Sunon V2-1 along for replacement later on. Automate it with an thermostat seems a good idea. Will follow thread on that.
[Android Head-Units] blue_one:
Did anybody discover what our Chinese friends mean with the latest firmware changes?

3. Add button sound

4. Add the function of forced upgrade system

5. Optimize the problem that google related processes die

I couldn't find anything new.
[Android Head-Units] Clyde72:
As for Google related processes I had Maps crash from time to time but mostly when it was launched via Assistant Voice (manual launch GA & then Voice) or when Maps launched from Calendar. So when one Google app calls another Google app. Launching Google Maps (my standardised Nav) directly works smooth. Have to find out if it is more stable now... but TXZ is still the propriety service in the background so I guess conflicts will remain.

No idea on the sound button and didn't see changes in update features - though forced & upgrading doesn't sound healthy...

Ran everything through Google Translate again (Chinese traditional & Kantonese traditional), seems like 3 should be "key tone" in stead off "button sound", no idea put maybe it is an option to switch key tone on when tapping/stroking keys. Like it is possible on phones and tablets...
[Android Head-Units] Aaantonn:
I will redo the entire cooling system in two weeks, I will show how I did it and tell you all the dimensions. I have to take it apart twice more to get it all done.
[Android Head-Units] Aaantonn:
On the day before the system update, Google hung up on me, and so seriously that everything connected with it turned off, maybe this is point 3.
[Android Head-Units] Aaantonn:
Who can write the meaning of all these components? Where is the processor, where is the memory, where is the amplifier? I want to make cooling of all components with the help of radiators, there is enough space and it is very interesting to compare the indicators before and after. It is especially interesting where the temperature of the amplifier is shown! I saw a video on how to improve its cooling.
[Android Head-Units] blue_one:
The whole housing is a radiator. The amplifier is connected to the housing with thermal grease. Inside the housing there is no more room for additional radiators. The best way would be to cool down the housing with a big fan like 12cm.

You can see the disassembled unit here:

[Android Head-Units] marioti:
So, i'm curious, why the processor is without any cooling
[Android Head-Units] blue_one:
You mean that unit from my link? That's the S3 without active cooling. The S5-8 has a fan.
[Android Head-Units] Clyde72:
S4 has also a fan...
[Android Head-Units] marioti:
we know there is optional fan, but why the processor isn't cover by this heat dissipation plate or why there's no radiator. It would be better solution, instead only fan
[Android Head-Units] Clyde72:
maybe because there was no head room for heat sink, you could maybe stick thermal foam pad to the processor so the back casing serves for better heat dissipation
[Android Head-Units] blue_one:
Regarding to my unit there is a thermal pad on the processor.
[Android Head-Units] Clyde72:
Thx, I didn't open mine up yet. So they designed it with proper heat dissipation in mind

Hello to everyone. I have a problem with my S8. After 10 minutes not touching the screen the screen touch stop working . If i connect a USB mouse the device is working. I have to reset all the time . Sometimes the touch screen is inverted the right up corner is the low left corner . Any idee how to solve the problem ?

I attached the log files
[Android Head-Units] popamor:
Try to recalibrate the touch screen. I remember in one of the upgrade steps instructions saying that after firmware upgrade, if you have screen issues.
[Android Head-Units] slyver2008:
I already did that more then 3 times but nothing. Usually after 10/15 minutes the touch doesn't respond anymore
