I changed it to the latest version of the MCU, the voltage readings on the battery worked.

THANK YOU FOR YOUR ADVICE AND HELP!
[Android Head-Units] Clyde72:
I have an Golf V and no canbus connection and battery voltage is shown since 2 or 3 updates ago. After some firmware update.

It just sences the voltage fed to the unit no matter how it is fed I guess. That sensor (hardware again, part of overvoltage protection I guess) must have been present all along, some software change made it to get read out via mcu an displayed I suppose.
[Android Head-Units] nyp42:
I briefly tried tried SVC with the Spotify Lite and the default audio player. It didn't seem to do anything for either of them.

The disable back up camera has been working since several updates back BTW.

Also Z-link is now the default Carplay app but it still isn't activated. Anyone know how to activate it.
[Android Head-Units] Clyde72:
Thx, will test thursday, will need to do some highway on my route then...

I remember an update but my canbus is still not reconnected. Will do it ounce I get the unit back out for the fan & mic mods a.o., was following these mods ever since...

You can change it back to Carletter if you want, that option got added too in the factory settings.

Otherwise maybe this helps
[Android Head-Units] nyp42:
Has anyone been able to activate Z-link like this. The screeen I get is different than the one in the video. The one I get has a QR code and is asking you to scan it with some app to activate. I suspect we may need to contact the vendor to have it activated.
[Android Head-Units] Clyde72:
No idea, just a link I've found. Never tried Zlink and I don't use Carletter. What would be the difference between Zlink & Carletter in fact? Seems quite similar and both evenly limited to me.
[Android Head-Units] nyp42:
I think z-link can do wireless Android Auto.
[Android Head-Units] Clyde72:
Carletter also, at least when I tested it when I installed the unit but I installed my preferred streaming apps, parking app, nav app etc on the unit itself
[Android Head-Units] nyp42:
I thought it could only do wireless Car Play and Android Auto needs to be plugged in.
[Android Head-Units] Clyde72:
Needs Android 12 on the phone if I'm not mistaken
[Android Head-Units] popamor:
Never mind. Saw that you have ficed your issue with MCU upgrade.
[Android Head-Units] Meteordust:
For the one that is buying the V2 Sunon fan, 7500 rpm for replacement of stock fan.

Tried two solution:

1) Putting it on 9 volt with a L7809CV...hardly noise but worried about the amount of airflow.

2) Put a resistor of 135 Ohm, power supply was 14 volt, voltage over fan was 10,75 volt, it makes little buzzing sound, but probably you will not hear it fitted in HU and in dash.

With stock fan and some hour of driving, car temp around 22 degrees, the fan app showed 55 to 59 degrees for CPU.

So my believe is that putting the Sunon fan from 7500 rpm to 5000 rpm is not wise, lack of airflow.

My fan delivered shows 0.52 Watt actually, little different from data sheet.

Comparing the two fan blades, stock and Sunon, the Sunon has wider blades, more airflow better static pressure.

Decided to put 135 Ohm, 10,75 volt when engine is running with 14 volt from the plug, this not from calculation but by measuring the voltages.

And this is a 2 pins, coz was reading somewhere only 3 points available, or he mend 3 screw to fit.....for 3 pins you can use a PWM controller.
[Android Head-Units] marioti:
Have you tried to fix thermopad, i have it but it was to thin and chinese was place it wrong, did not touch the metal case
[Android Head-Units] Meteordust:
Who you ask....
[Android Head-Units] Clyde72:
"2022-12-16 update record:

4. Display the original car battery voltage in the status bar"

1216 was an major upgrade with a lot of functionality improvements even without canbus (disconnected my canbus in November)
[Android Head-Units] Clyde72:
You can also use factory code 332211 to test with new fan which will keep cpu & gpu temp on screen, same code to disable it again
[Android Head-Units] marioti:
You :)
[Android Head-Units] Meteordust:
Well I will not use a thermopad, it's proven that for contact between a CPU and housing it will do worse, most are only 6 and max 12 W/mk, thermopaste you also only use for filling up the microscopic holes in the surfaces of CPU and cooler, a very thin layer.

Thermopad I would only use in a situation with totally no airflow, to have at least some cooling, that they do with IC or other parts on graphic cards and so on.

Better use copper or aluminium between CPU and housing with little thermopaste, you can also make one yourself from aluminium foil to the exact thickness, copper/aluminium has much better W/mk like 20 to 30 times better then a thermopad.

But I could be totally wrong :eek:
[Android Head-Units] marioti:
Agree for all. But.

Cpu isn't flat, with shiny surface like in a computers. the CPU in our HU, and a housing also, is really scabrous. You can always try to polish the aluminium housing, but not the pcu, because is a plastic. Thermopads are also present in a computers and laptop, eg. on a RAM, etc. So i gues, the thermopads are better then nothing between cpu and housing (the gap was 1,6mm).

In my case, under the fan is solid plate cover all bottom, so the airflow around the cpu is questionable. I'm thinking to cut this, and leave only around the CPU.

Anyway, i'll do some tests, and find out myself what is better in my case. For now i filled the space between housing and CPU with 1,7mm thermopad. Next, i'll try with Aaanton idea (and yours too), to go with 1,4-1,5mm thickness cooper plate and some thermal paste (i got MX4 at home)
[Android Head-Units] Aaantonn:
I made myself a week ago, I used a 1.2mm copper plate. and a Honeywell PTM 7950 phase transition thermal interface. I just pasted a thermal interface onto the processor, then a copper plate, then the thermal interface again and closed it, through the fan hole you can see that everything is pressed well. Now the temperature of the redeco processor reaches 50 degrees and the fan turns on very rarely.
[Android Head-Units] nyp42:
I have found that if you run a fan with a hydrostatic bearing to slowly it will wear out very fast, FYI.
[Android Head-Units] marioti:
I just discovered, that my housing is weird, it's not cover whole cpu, as yours. I have to figure out something.

About the temps.

Conditions: - in idle, on table (i can't test it in car yet), run google maps, the temperature between 38 to 41 C (shown on fan app)

But it can easly and fast jups between 38 do 56, if i just do any operations.
[Android Head-Units] nyp42:
Can anyone find the datasheet for this CPU? I usually don't worry about CPU temps until they start to approach 80 C.
[Android Head-Units] Meteordust:
I'm running my fan on 90-95% speed.

I re-adjusted my fan with a 68 Ohm resistor, 135 Ohm is too much and not needed to cut down the noise.

Fluctuation in temp with 135 Ohm was 50 to 59 degrees, like the old sock fan without resistor, using Sygic or video.

With 68 Ohm, it is 40 to 50 degrees, car temperature 23 degrees with 1 hour driving, so inside dashboard it is warm ..

Fan fitted in unit and some static back pressure does not make sound that is annoying, not buzzing, hardly hear it ..need to put my ear almost on the HU to hear it, with only key in lock, no interior fan or engine running.

It's fine for me, CPU should be able to handle 60 degrees easily...and have airco in the car .

Final, with Sunon fan V2 ,with 68 Ohm resistor, temperature dropped with 15 degrees and less sound compared with the stock one.

Mentioned before fan blades of that stock are small, Sunon almost 2 times wider and probably more static pressure and airflow.
[Android Head-Units] Clandaries:
Is it possible to reset the MCU settings?

Hizpo tries to tell me that it is normal, that just the multimedia keys will work on the steering wheel.

Also does the frame of the head unit not fit 100%

They will give 20 Euro refund.

I am very disappointed so i will send it back.
[Android Head-Units] Meteordust:
Agree a little bit :cool:, thermopads for what you mention are parts that don't jump up and down in temperature that quick.

A CPU needs immediately good cooling when load goes up, fan speed up and big cooling body.

On Youtube you can find tests with thermopad, nothing fitted and thermopaste between CPU and cooler, immediatly CPU goes in trottle with a load on the CPU when the expensive thermopad is fitted.

You will see that even without any paste or pad you have almost (+5 degrees) the same cooling as with thin layer of paste.

For quick responses a thermopad acts like an isolator, the difference between W/mK is huge between copper and pad and says enough.

So if I would do something, I would go with a copper plate, like @Aaantonn, didn't took off the mainboard of my housing myself, not worried when I see now with my Sunon V2 fan with 68 Ohm resistor that it not going above 50 actually.

And really no annoying sound hearable.

Switch fan off also don't like, not because of the CPU but because of the heat coming from the other side, where power connector is fitted, that area becomes really warm, so fan blows air in unit to push out warm air in general.

This kind of CPU's are designed like this to fit in small housing applications, also without any fan or big cooling bodies.

Although that is what I believe.
[Android Head-Units] Clyde72:
I'm searching for an screen recording app to analyse temp over longer drives without fan.
[Android Head-Units] marioti:
1. I'm trying to connect my Viofo A119 dash cam to HU via AV. But viofo got NTSC, and the picture on HU is black-white and "jump". Is there a way to set NTSC in CVBS-IN line?

2. Anyone know where i can find a ready boot animation to Skoda in 1280x720.

couldn't find it here:

https://xdaforums.com/t/mod-boot-animations-taking-requests.3351617/

3. Meteordust, You got right. I'm going to go on cupper plate and thermalpaste, just like Aaanton.

4. I have tested the microphone (the modification with extended wires and foam :) ) I talked with my wife, first direct via samsung s21, seccond via bt connection with HU. She said, better was via HU :)

Ofcourse it was in pretty quiet environment in my garage, but still i can said, it is good job :)
[Android Head-Units] Aaantonn:
This is normal when the temperature jumps sharply, some operation is turned on, the processor crystals heat up, sometimes for a short moment, and sometimes until the operation is completed. In this process, the main thing is not how it jumps, but how efficiently the heat is removed, as you understand, it will not be removed without being pressed against the body. You need at least a thermal pad or it’s better to buy a thermal interface as I wrote above and through a copper plate, cut it 8-8mm (the plate is sold 15-15mm on aliexpress). The phase thermal interface has crazy heat transfer! I use it on a gaming laptop. I do video editing all day, so any thermal paste becomes unusable in 4 days, from high temperatures, and the thermal interface works well. It is specially made for processors.
[Android Head-Units] Aaantonn:
I'll give an example: CORE i7 processor 1) Arctic MX-4 thermal grease - temperature 64 degrees on the first day of operation, 68-74 on the second, 80-90 on the third, fourth day, and on the fifth day 97-98 degrees! Pasta doesn't work anymore! 2)Arctic Termopad Thermal Pad 0.5mm - a week of work at a temperature of 80-92 degrees, the temperature is higher than with the paste but does not rise higher! when removed, the thermal pad remained soft and functional. 3) Honeywell PTM7950 termopad GPU - constant temperature at full load 66-68 degrees, there are jumps, but they are not considered. I don’t know how long it will last, but with my loads for a year it will be super! What is all this for - a thermal pad is better than nothing, I checked it for the sake of experiment, it’s bad, but it works, I saw a picture here, someone put it up, he has a thermal pad glued on the processor.</div>

In general, I think the radio tape recorder will work as it is, since they are all made according to the same prince and so far I have not heard that someone burned out. I think when overheating, the processor will go into protection, it will start to slow down and that's it. But the power amplifier at a temperature of 70 degrees loses more than half of the power, as it is written in the description of the amplifier, it is better to immediately replace the paste with a good one on it.
[Android Head-Units] Aaantonn:
Maybe someone saves their MCU ???

I really need MCU QF 01.51.20220913.002121

Very necessary! If you have please share!
[Android Head-Units] Meteordust:
You need the bootanimation like on that page?, because they show one for Skoda but indeed only on 1024 x 600.

I also modified one for my Opel, it doesn't matter if it is in a little smaller size, it will just be centered and a littlebit smaller, and you need to modify it a litlle, fps, rename it.

With Photoshop with a recorded "Äction" you can simply re-size, rename all the files in a minute.

My Opel animation I needed to modify a little bit, coz of the many files, it took to long to play, part0 of bootanimation you want to play all files, part1 is just a waiting time for device ready to homescreen.

Our HU starts up fast, so if I would play part0 like part1 (set in desc.txt) the animation will not be played fully, or set a much higher fps, but that looks to fast when playing.

So if you need the Skoda one from that linked page in 1280x720, I can simply re-size it and modify it, but I would go for a little smaller size than actual screen resolution.
[Android Head-Units] marioti:
I'm trying it myself, but i don't know if i'm doing it right. 1. I change pictures res. in part0 and part1 files to 1280x720, but if i want to save proportions, it gives me 1229x720. 2. So in the desc.txt i should change it to string 1229 720 20? (with no changer in the rest)? I think this 20 seccont should be fitt for our HU

2. In the instruction they said - Change permissions of "bootanimation_dancing_droids.zip" to "644" - but what it means to our HU?

So. If you have some free time, can you please do this with Skoda2 files :)
[Android Head-Units] xdsbx:
Iv done it as it says on the first page. It worked for me. I tryed to rotate it in windows Paint.
[Android Head-Units] marioti:
you are saying about a boot logo. I'm talking about the boot animation :)
[Android Head-Units] Aaantonn:
Maybe someone knows if the old version is stored in the system after the MCU update or is it immediately cleared? Where can you search?
[Android Head-Units] Clandaries:
One question.

Whitelist apps does not work. Apps get killed.

Is there a anoter working way to get apps to autostart?

Regards
[Android Head-Units] marioti:
i have made just like on this video. system updated itself and... there is no boot animation right now. System booting longer. i changed pictures to a bmp files (original are in png), not working

Also i try to change boot logo like on the first page. i have boot logo in 720x1280, and .bmp format. Copied it to root in pedrive, but system do not see the file. (i can't attach here a file in bmp, to show You)
[Android Head-Units] Meteordust:
Hi, you don't need to copy the animation to root, it will load automatic when you put it on usb stick in QF/auto/ folder, so need to change permissions.

Well it is about dimensions, 1024x600 is different from 1280x720 if you scale 1024x600 to 1280 wideness it would be 1280x750, your 1229x720 is actually 1228,8 x 720

That's why I use Photoshop, record my handlings I do, as an action, and do a batch with that action for the around 150 files I think, so automatic convert the files in just a minute.

Will download your Skoda and have a look.

As long as your size is not bigger then screen resolution of your unit it will work, it will be centred.

Our stock Android boot animation has dimension of 640x180 so 1024x600 already will looks nice on a 1280x720 screen.

You then only need to change desc.txt to your likings and rename it as bootanimation.zip

When you unpacked it you need the pack it again in zip with method store, otherwise not working.

But no problem if you really want 1280x720, think Friday will have time.
[Android Head-Units] marioti:
Now, I used Light Image Resizer and set without proportion to 1280x720, update the desc.txt (just wrote new res.) then put all in QF/auto/bootanimation.zip

and i think something was mess up in the first time. HU did not see a pendrive.

I tried annother one, with just a music in .mp3 and it not see it. In file explorer i see ony internal disc
[Android Head-Units] Meteordust:
You need to copy to usb root in folder QF/auto/

This two folder you need to create on USB stick and in auto folder you paste your bootanimation.zip, no other name like that.

If you unzipped it and zipped again, use method/level store, otherwise will not work also.
[Android Head-Units] Clandaries:
For Suzuki Swift Sport
[Android Head-Units] Meteordust:
If you just scale 1024x600 to 1280x720 , you crop the height to smaller size, that will not look nice with round things in the pictures, like stretched in wide.

Stock Android bootanimation, with only 105 png24 files total, desc.txt looks like this.

640 180 20 (dimension of the jpg or png and fps)

p 1 0 part0 (means play all the files ones)

p 0 0 part1 (means loops till device ready to start homescreen)

If file explorer only see internal disc, your usb stick not working..

So in your case, just rename the zip. remove that _dancing_droids and just try first with 1024x600 how that looks, this is probably made for a 1280x720 screen and desc.txt looks okay already, no need to unzip and zip it again, and if you do, zip it with method/level store.
[Android Head-Units] marioti:
Ok it'll be better to wait for you till friday:)

I reset to factory. Boot amination back to original. But still do not see a pendrive in factory file Explorer, or music app, etc. I tried all I have (11 pcs)

Weird because i've done the sys upgrade yesterday, using one of my pendrive
[Android Head-Units] Meteordust:
Yes that is weird....cable ? I also made mistake ones, wrong zip level, animation was just a black screen, but could just redo it...so don't see relation with your bootanimation you created..

Normally after start up you see a popup that it will update the animation with an automatic reboot...if it has the same date and time as the one already installed it will not update again.

To make animation you can also use boot animation factory, google it, it is free, you can test your files, set fps, it creates a desc.ttxt file when save it and will be correctly zipped.

Okay will make a 1280 of it...no probs..
[Android Head-Units] Telperion:
It's in /data/QF/ I believe, or /great/QF/, I don't remember which. Or if not there, from a root shell use your Linux file search command of choice to locate it in the filesystem.
[Android Head-Units] Meteordust:
Oeps thought it was about the boot ani....removed my reply
[Android Head-Units] marioti:
I was use one of the original usb cable, but I was connect also this seccond one with no luck

Thanks in advance for bootanim..
[Android Head-Units] Meteordust:
Looked in your skoda file...one thing is weird it has several no 1.jpg with each time a 0 more, it should not be like that.it should start with 001.jpg,002.jpg and end on 150.jpg or something, not like 001,0001,00001.000001 and then 002,003. and end on 150.

But will correct that, but don't understand your usb in relation to updating bootanimation, hope you find the problem.

Did you see the screen the first time that it was updating and auto rebooted..?
[Android Head-Units] marioti:
please get that seccond bootanimiation "Skoda2", there are .png files, started from 000000001.png and finish on 40.

Yes, at the first there was a window (Bottom middle on screen) with information about autoupdate MCU... or something like that
[Android Head-Units] marioti:
ok. i don't know what just happened :) i left HU in idle (just google maps in background), and went do some stuff. When i came back after an hour, i tried again with usb sticks... and... They work normally, all of them, even Sandisk 128GB with card reader :)

Then i check the temps - see the thermal picture. As you see, the hottest place is on the power supply section, not the cpu area. The fan was disable all the time

Can you all, recommend a good launcher? Agma is ok, but it is only 30 day trial, and don't know do i like it so much to buy. Nova launcher it is not my style.
[Android Head-Units] WarSpaz:
Hello,

I am thinking about buying one of these units for my Kia Optima.

I would like to ask someone that got one of these units to try NavRadio+ on it and see if it works.

This app only works with certain mcu's/apu's etc so it would be nice to know if it works or not before i hit that buy button.

Link to NavRadio+ (there is a free test version): https://xdaforums.com/t/dev-new-nav...-intel-ts10-uis7862-and-ts18-uis8151.4024701/

Thanks in advance if someone could try it out!
[Android Head-Units] Aaantonn:
I installed, it works, but I did not use it, everything is paid.
[Android Head-Units] WarSpaz:
Thank you for trying it out!

The free version should only be used as a test, but if working should still be able to get radio frequensies and sound from it. :)
[Android Head-Units] Meteordust:
Weird, did you also had a mcu.bin in that folder, coz it should show bootanimation updating and after that a reboot, I did it more then 10 times so....

Yes see the Skoda2, it is smaller, part1 is only one png, you should modify the sec.txt in that situation, set amount of frames, like p 100 0 part1, with 20 fps it will be shown for 5 sec.

I will make it 1280x720....and add 20 files in part0, so it will come up from nothing shown to the one that is now 0000001.png. btw this png is a firework one, when I save it as web based png-24, like normally in a bootanimation in Android it is half the size in kB, so my created will be smaller in kB.

Will do it when I come home later today.
[Android Head-Units] Meteordust:
@marioti

Here your 1280x720 bootani based on that Skoda2 + bootlogo Skoda2!!

Animation put it like you already did in root USB QF/auto/

Put USB stick in USB connector before you start unit, it will load after the startup, it will show on screen it is updating the animation and will reboot HU automatically.

Animation I made is as long in duration as the original Android animation on our HU and also 105 files (y)

Bootlogo I needed to zip, otherwise wouldn't upload as bmp to this thread, so unzip and put it in root USB and the rest you know probably, to set new bootlogo, do NOT rename it as bootlogo.bmp
[Android Head-Units] Clandaries:
@Meteordust

Could you make one for the Suzuki Swift Sport?

I would also buy you a cup of coffee :)
[Android Head-Units] Meteordust:
LOL....I can't find a nice Suzuki bootanimation after some search....the one on that thread with all that animations for several cars has a Suzuke but that is not the one you want.

Even the original bootanimation of Suzuki entertainment system is only like an S coming up and blinking a little bit, at least so far as I can dig in the firmware I downloaded, if you want that in can make it, but it is in mp4 so need to cut it in pieces.

But not going to design myself a brand new one for Suzuzike Swift Sport, that would take first too much time and is of personal liking, maybe I like it but maybe you don't ;)
[Android Head-Units] Meteordust:
Happily USB function came back.

I use Agama and bought it, just because I can set the colors like all my leds in my car.

Almost all functions work, only have problem with daily km reset, this because I have no powersleep, so it will reset it after every startup, so put that function off and do manual reset if needed.

BTW uploaded your bootanimation and a bootlogo, thread number #1,166
