Measuring the steps doesn't help us.

Since you have already checked Min and Max, and reports differences between you S1 and S6, we have at least understood that something is different between the 2 mainboards and related backlight power circuits (maybe...) but what?

Are both of you left units with black MB PCB?

QF03 native MCU both?

If you want to take photos of the 2 mainboard PCB, in HD, of the area where you see the connector that powers the display, I can try to see (as far as possible with a photo) any differences between the electronic components present there... but I repeat without electrical schematics certainly can't find out everything...

Hello, I have a problem with the latest version of Sygic on the device, there is no notification sound and it seems that it cannot run in the background with online radio, eg. spotify
[Android Head-Units] Klag3:
Thank you very much for the advice, everything worked out, I am very very satisfied, the update was successful
[Android Head-Units] PrinceLc:
Someone noticed maybe MCU QF05 or Last Firmware that the headlight regulation for light dark theme don't work.
[Android Head-Units] Barykelo:
works for me
[Android Head-Units] PrinceLc:
Ok thanks for answers

Hello,

I have an issue with updating MCU after successfuly updated firmware unit on the newest version.

Issue message is: "Update file is not compatible with current platform!"

I've got MCU update package from autofather.com with choosed correct DSP IC is BD37534 and radio IC TSC4745 - thats why I'm wondering, why it is not compatible MCU update package.

Did I miss some step in between?
[Android Head-Units] PrinceLc:
It's compatible you need to set in factory code section 774411 and then you can update

After updating FW and MCU to 2024 version the sound is not loud enough.

After a phone call the sound is normal again but it works until reboot.

Any fix for this?
[Android Head-Units] PrinceLc:
Install the 19th January version the previous from 11th have this sound issue
[Android Head-Units] ImBenny:
Thank you for reply!

Unfortunately I installed 20240119 version already and I get the problem. :/
[Android Head-Units] PrinceLc:
Hm ok then only a factory reset can help
[Android Head-Units] ImBenny:
I resetted and reinstalled update with wiping user data but didn't solved the problem.

I'm getting tired of the messed up updates....
[Android Head-Units] L3nny_:
Try to reset wifi and bluetooth data, there is an option for it and also rename device bluetooth name. This helped on my side, no needs to do factory reset :)
[Android Head-Units] ImBenny:
I tried this and didn't worked.

I tried wipe 225588 and 22558800. Wipe, reinstall, wipe

Nothing helped.

I think something is wrong with the "Default volume"

When I set it 0 and reboot. There is no sound.

When I set it MAX, the sound is incredible loud.

Only calling set it back to normal work.

I don't use it but I noticed that the "Buzzer" also don't work.

I also see that this new update fakes Android 13 from now and not 12.

I think I roll it back to the previous very stable 20230615 2.57 version and stay with that forever. It is so boring and tiring that I have to delete all of my settings and wasting hours to keep the device up to date and it always gets worse on lot of try.

From Youtube, a guy make a video test with this two display:

WD090HBM30AC-SO YT090IBNXL006-BS7-30​
[Android Head-Units] Micky001:
I "solved" this problem, by cutting the lights signal wire, that comes between the canbus and G socket(main Power/speaker, pin 4 "ILL"/"Lights"), and I set in the Agama Launcher, the switch on theme, depending by time. GPS time.Anyway, with the lights On, even in the daytime theme, I still had "a small" brightness dimming before, which for the anyhow low brightness display of the S4, was annoying... The first "solution "with the new rules, it was by covered the car light sensor from the dashboard ... Thus, with the lights set to AUTO, are automatically turn ON, regardless of whether it is day or night .And I no longer have to operate manually, or... forget to turn them on during day time . My car it is an ..."old style" one
[Android Head-Units] Micky001:
I saw, and based on what I saw, I ordered that display. However, it seems, based on our colleague's tests, after he received one , that both have the same "problem" with low brightness.

So...I canceled the order.
[Android Head-Units] Barykelo:
I had so much fun with this video!😂🙄
[Android Head-Units] MauriBixio:
Yes, funny, the boy waves "Ok"... :)

Definitely... with all these displays on Sx units we will probably have to resign ourselves... they are not very bright.
[Android Head-Units] Bushido1992:
Yes, the seller told me the same thing, but that didn't help. I tried two SIM cards (the second without a PIN). Neither one was detected in the unit...they work correctly on my smartphone. For the Unit i used a Nano to micro Adapter.

Well, I have to find the time and want to try it live one day... :D
[Android Head-Units] PrinceLc:
Had this display too seems all the same in brightness
[Android Head-Units] lone_slayer:
It's summer where I am. First start up of the day I would get a noisy fan noise on start up immediately and have had this almost since i installed the stereo. I have had it once about a minute after start up since I updated. The fan is still working and it's only ever been noisy on the startup
[Android Head-Units] marioti:
left side is only slightly brighter, and more eyes friendly (warmer white)

are you able to make it temperature dependent?? Im getting annoyed by the noise of the stock fan....
[Android Head-Units] tomdevries:
hi guys,

i've installed a s5 in a c4 picasso with a canbus box. I'm able to do all kinds of things with the SWC, but unfortunately nothing happens when i press the voice activation button on the wheel.

Is there a way to analyse whether i have the correct canbus profile? In the settings there is no 2010 c4 picasso in the citroen section. Hiworld doesnot respond...

furthermore: i installed vivid launcher, but i'm not able to make it default, and also not possible to select spotify in the music section, only local music allowed...

hope you can help me out, thanks in advance!
[Android Head-Units] Clyde72:
@fjavierb @shammeel please try to stick to English, we are on an international forum/thread after all, thx
[Android Head-Units] Clyde72:
Voice Activation only works when you purchase a licence for Toppal I believe or when you have another Assistance service running in the background so probably your canbus decoder & SWC is working just fine
[Android Head-Units] blue_one:
Nope, the integrated temperature fan control only works with mainboards younger than December '22. Mine is older. It would be possible to use a simple ptc/ntc temperature control on the fan if necessary. But for me it's quiet enough without any control.
[Android Head-Units] tomdevries:
would it be possible to switch to Google Assistant and get the button on the steering wheel working?
[Android Head-Units] Clyde72:
Possibly yes but I suspect GA service should be running in the background for it to work. Still working on that

No need to cut the internal one

[Android Head-Units] L3nny_:
I have S4 and I see that shown battery voltage is not very accurate. Battery status in tray shows 12V but real voltage on battery measured by multimeter is 13,2V. I understand that shown voltage that could be voltage inside S4 and not exactly on the battery itself, but my question is if I can add some constant value to the displayed voltage to correct and display the actual battery voltage? Does somebody knows?

I also searched if exist some aplication what could also show battery voltage (or condition etc..) through S4 unit, but I found only aplications which are only able to connect to some bluetooth device directly connected on car battery (BM6, AEG, ...)
[Android Head-Units] akos_202:
Hello everyone!

I have bought an S5 version, from Hizpo.

Everything works fine, except one thing.

It is installed in a Audi A4 B7, non-Bose, wired everything up, it came with a p&p adapter for the car. The car has a factory amp in the trunk, which powers the rear speakers and the sub. The front ones are not ampered, and they sound fine. Now the problem is that the rear speakers and the sub has very very low volume, if i fade it to the rear, you cant hear anything.

I’ve read something about Hi-lo converters and things like that, but i am not sure what i need to make it work.

The amp has the power on, and the trigger from the head unit also has the 12v signal.

Anybody had similar issues?

Thanks in advance.
[Android Head-Units] cleverdicky:
Check you haven' t mixed up the pre-outs
[Android Head-Units] Peixeiro:
Hi, What is the main propose of this app?

I have a Peugeot 407, and the only thing that doesn't work and I think it would be important are the car's errors. When I open a door or the trunk, a popup appears with a drawing of a car with the door(s) open, but if a light bulb breaks or a tire gets a puncture or any other error, nothing appears on the Android radio. Just the symbol on the small quadrant screen.

This app it's a solution for this?

In the strings.xml there are errors and warnings messages...
[Android Head-Units] MauriBixio:
Simple, no.

And the ones in the link are also not updated.

Everything you can have via canbus on the radio depends on the car/Brand/canbus box used.

So, don't hope to have a lot of things with stock CarApp of these units, but rather, you will have very little, just popup doors open, rear cam auto switch, steering wheel controls, external temperature and little else.

With some VW group cars (and very few other brands) it is possible to have some information on the engine, AC climatic control.

With BMW for example I only have what I wrote, no engine data info, no AC climatic control via radio (and I tried 3 types of canbus decoder, of different brands, and all "theoretically" suitable for my car model/Brand) so ...
[Android Head-Units] mtzonev:
Hello everyone, i bought that cam:

Podofo Dash Cam ADAS Car DVR ADAS Dashcam DVRs Video HD 720P USB TF Card 16G/32G Auto Recorder for Android Multimedia Player DVD

but installed DVR didn't recognize it. Do you have the same problem?
[Android Head-Units] akos_202:
There’s a red and a white rca plug coming out from the headunit, labeled AUDIO OUT L and AUDIO OUT R, there is also an RCA plug in the adapter’s connector (aux L, aux R) which goes into the original radio loom and that goes directly to the amp in the trunk.So i guess it isn’t mixed up. The amp is powered on, and also trigerred by the headunit, but has very low volume, you can only hear it if you crouch by the rear door’s speakers…
[Android Head-Units] MauriBixio:
Use the app that comes with the dash cam and not the stock radio one, which does not manage ADAS devices.
[Android Head-Units] Micky001:
ADAS cameras usually come with their own application. Open the corresponding USB device in the file manager, and see there if you have( it must to be there ) an application to install. At least, that's how it worked for me. The camera has its own application, I installed it, updated the application, set the resolution and that's it. After that, in the theme I can associate the application if I want the video capture to be permanently present. But, the camera's own DVR app.
[Android Head-Units] mtzonev:
Thank you for the answers!
[Android Head-Units] cleverdicky:
no, aux l/r are generally inputs to the radio. You will probably have a yellow one somewhere also for video. These are for connecting external devices. (I used to have a tv tuner on mine.)

Im afraid i dont no your radio so dont no your connectors, but there are normally 4 pre outs. fl, fr, rl,rr + a sub if you have that.

Perhaps if anyone is familiar with the make / model of your radio they could better advise what you should have.
[Android Head-Units] marioti:
Are you sure the HU triggering the amp? First, it have to be ON, in the 8888 factory menu. Then check the voltage on this cable (also, do you know what voltage trigerring your amp?)
[Android Head-Units] akos_202:
Yes, i can measure 12volts on the trigger line in the amps connector,(originally, the amp turns on from the acc, so it is correct). The power amplifier switch is ON in the factory menu.

Hi there, i have hizpo S8 8/128gb, and it works fine but i am wondering if there is any solution to show fuel consumption with any app on my head unit. My original radio on renault trafic „media nav“ was able to show me total consumption, total distance and more… (see picture) is there any to read this informatios from my car on my android head unit? Thx
[Android Head-Units] MauriBixio:
Look at my diagram below, I highlighted the colors/wires of the 2 USB sockets.

Stick to those...and see where the red wires of the USB power bus are located in the 2 sockets. Maybe one of these has come out and needs to be re-positioned.
[Android Head-Units] -fluffy-:
U shut be able to do that in central control of the original car an then car computer
[Android Head-Units] MauriBixio:
EVERYTHING you have via canbus on the radio depends on:

- Car/Model/Brand

- Canbox decoder dedicated to your car/canbox manufacturer

Therefore, what you can have is subordinated to that, there are no fixes to be made, any OTA updates of the canbus firmware are related only to the stock CarApp of the radio, NO to the firmware of the canbus box chip, therefore... it will not increase the functions displayed via the radio,and each car/brand can show more or less information/utilities (which ALWAYS remain VERY limited, in any case).

Ultimately, the canbus box with these units has VERY limited potential, it mainly manages the steering wheel controls, auto switch for rear cam, the rest is ONLY possible based on the car model/car brand.
[Android Head-Units] itiswitis:
I haven't seen a solution that's as good a match to the factory setup. If your canbus/CARApp doesn't support it, try Torque Pro (if you are able to use an OBD2). It can use data from the OBD2 to "calculate" fuel consumption, although not perfectly accurate. Car Launcher also provides trip telemetry, but not fuel consumption.

[Android Head-Units] Vampire_Dracula:
Use this FM amplifier: https://www.amazon.com/dp/B07N8LRTT5

It solved the poor FM sensitivity for me.

But I advise against NavRadio+ for S8 head units. It doesn't work well with Google Maps navigation. The FM sound is interrupted by the navigation guidance even when muted.

It makes it impossible to properly listen to FM music.

There was a solution in dedicated thread. You need to reset bluetooth. Here in s8 i have only basic navradio (free) but the solution work for me

Thats a REALLY old firmware version, use the one from autofather instead: 20240111 -> https://autofather.com/s_sjjc

Anyway, no sound to speakers sound like you have a amplifier in the car, have you connected the black/blue wire to the amp signal cable?
[Android Head-Units] Elrathias:
if you have the spare cash on hand, its a wonderfull thing to have. a one channel is sufficient for simple work, but a 2 channel is good if you want to try and sell it again.

FNIRSI has a 110mhz oscilloscope 1c15 (mhz is bandwidth, how many times per second they sample the incoming signal. way WAY overkill for simple digital signals, a 500khz DSO-03 is _good enough_ for the basic kind of troubleshooting you are probable to do. so thats about €45.

rear speakers are connected to my car amplifier, front speakers are connected directly

I did a factory reset and not fix the problem
[Android Head-Units] Elrathias:
Thats because you CANNOT wire any car stereo like that. You are basically taking the master signal, and splitting it into two paralell circuits, giving a equivalent resistance of 87ohm instead of 600 OR 100. Because the RCA outputs is for the FRFL audio, not RRRL.

Draw us a picture that says exactly how you have wired the stereo, including if you have manual power to the amplifier, or have connected it to the black/blue wire on the harness for auto-power on.
[Android Head-Units] Aseedi:
car electrician who connected the wires, after first installation for multimedia the sound was working, several months later it stop working.

in second installation i replaced all 4 speakers, and he check with only one speaker connected and the all other components not relative disconnected still has no sound.
[Android Head-Units] Vampire_Dracula:
That's not a "solution". I tried everything, (including upgrading the HU to the latest firmware, as suggested by the developer, after I contacted him) and as I said, the developer himslef admited that there is nothing else he can do, because it is a Blutooth API problem. He refunded my purchase. That's too bad, because I liked the logo feature and I really wanted to make it work.
