[Android Head-Units] Bastianino:
yes, it's the first thing the seller asked me, even though I had connected the gray connector well
[Android Head-Units] marioti:
No idea, looks like canbus not working.

Try to force your seller to send to you a new one. They should do it.

if not, it cost ca. 25$
[Android Head-Units] Scale&Hardwarebox:
Hi, i´m new in this forum.

@Bastianino

Did you try to config your steering wheels buttons with the app in the head unit? I had similar issues with my head unit that the buttons aren´t detected (i have not a canbus decoder in my car). Open up first the app where you can bind the buttons. Then press at least 1 or 2 seconds the button of you steering wheel you want to configure. A message should appear in the headunit to bind a button.

The instructions say nothing about how long you should press the buttons on the steering wheel. At the beginning I pressed the buttons once and they weren't recognized. After I pressed the buttons for a while, they were recognized and I was able to program them.
[Android Head-Units] Bastianino:
thanks for your interest, I tried to program the buttons but nothing happened, but I didn't keep the buttons pressed for too long, I will try again and let you know
[Android Head-Units] Bastianino:
I already bought a new canbus (my seller disappeared and no longer responds...), I'm waiting for it to arrive from China (AliExpress)
[Android Head-Units] itiswitis:
Any data in the CARAPP? The canbus should provide some data and car options through the Carapp.

Also, did you connect the headunit to internet? Head unit needs internet connection at initial install for canbus to work.
[Android Head-Units] MauriBixio:
If you use canbus adapter don't have to use the app to map the buttons to the steering wheel (it won't work).

However, it is useful for those who DO NOT use canbus, with resistive inputs.

In you case, either you have a canbus adapter that isn't working, or the radio doesn't support your car, relatively to the steering wheel controls via canbus (but this seems VERY strange to me).
[Android Head-Units] Bastianino:
I don't know where to see the carapp information, when the installer installed the radio I don't know if he connected it to the internet, I always use it connected to the internet and when I tried to change the car settings in the canbus I was always online
[Android Head-Units] chadoe:
Also note there are two different steering wheel mapping apps on the device:

1) Carapp -> SWS Study (does not work on my Ford)

2) Car Settings -> General -> Steering wheel study (long press on wheel buttons, works on my Ford)
[Android Head-Units] itiswitis:
My car is the exact opposite. "Carapp/swc study" works on my camry, other options to change swc does not work.

Got my Ossuret S8 few days ago and made my own bootanimation.zip for Renault Clio 4 RS. I placed the file on a pendrive in QF/auto/ and did a reboot. The original boot animation is gone now but the new one doesn't shop up on reboot/cold start. What am I doing wrong?
[Android Head-Units] Bastianino:
Is your screen resolution correct with the bootanimation you created? with boot factory I guess…

I used the same process and it worked perfectly
[Android Head-Units] noyce:
Ossuret S8 is 1280x720 and the pics are 1280x720 (@ 72 dpi) as well. The bootlogo had to be rotated by 90 degrees in order to work correctly what indicates that the resolution is correct.

I didn't use Boot Factory because I'm on MacOS. I converted the video with an online tool from mp4 to jpg. I tried PNG too but that also didn't work. My S8 is switching directly from the bootlogo to homescreen.

desc.txt is:

1280 720 25

c 0 0 part0

Pics in part0 folder are named 000.jpg to 148.jpg

Shoud be fine!?

Apart from the bootanimation everything runs smoothly and I didn't encounter any bugs so far.
[Android Head-Units] marioti:
why do you have

c 0 0 part0

in desc.txt

i have

p 0 0 part0
[Android Head-Units] noyce:
c is for playing the animation to the end. p is for aborting animation when the device is fully booted as far as I know? Anyway, I tried both with the same result: Bootanimation not showing up.
[Android Head-Units] MauriBixio:
My files for boot animation,with S8, res. 1280*720 native ,have:

main folder name "part0" with 170pics, png format, res. 996*560 ( NO ROTATED IMAGE,ONLY for static fistrs boot logo have to rotate of 90°,and .bmp format for this).

second folder,name "part1" whti only ONE pic ,.png format, res. 996*560, NO ROTATED IMAGE (this is the end file of boot animation)

desc.txt:

996 560 30

p 1 0 part0

p 0 0 part1

tihs work perfectly!

For unzip, use 7zip,with this setting in picture
[Android Head-Units] noyce:
Why 996 x 560? and why part1? I have only part0.
[Android Head-Units] MauriBixio:
I noticed that with this resolution I get the optimal result with S8 native res. and the "weight" of the final .zip file is lighter (the greater the weight, the greater the probability of failure, better to stay UNDER 10 Mb).

The part.0 folder contains all the animation files, while the part.1 folder contains ONLY the final file of the animation, the one that essentially shows the last frame with the final static effect of the animation (only if you use the settings of my desc file).
[Android Head-Units] noyce:
Now that works with the smaller resolution of 996x560. Fun fact: The File size got bigger after i resized the images. It got from ~20 to ~50MB but it works! 😅

Hey everyone,

I've got a bit of a situation with my S5 and wanted to share it here to see if anyone can help.

My S5 had this issue where the display went blank while using a SIM card. It's a known problem with this device. I got in touch with the seller, and they suggested that replacing the display should fix it.

I replaced the display, the backlight is working fine, but I'm getting no picture. Now, I'm wondering if anyone here has ever replaced a display on an S5. If so, did you have to do anything special to make it work?

I've tried swapping the old and new displays multiple times to make sure it's not my installation messing things up, but the old display always works, while the new one stays black.
[Android Head-Units] marioti:
i see there upside down mounted the biggest ribbon cable. look at thre path
[Android Head-Units] inscriber:
Same thing happen to me. So I just keep touch screen for spare parts. Anyway the old display is Qled and new one is IPS so I decided to keep old display and not use sim card.
[Android Head-Units] jokex:
switch-off Data or remove sim-card from holder?
[Android Head-Units] IamPickleRick:
The screen went blank again, and this time, I didn't even have a SIM card in the slot. So, it seems the problem isn't tied to the SIM card. It's quite frustrating.
[Android Head-Units] marioti:
take the pins off to all the cable with sim card, and try.
[Android Head-Units] IamPickleRick:
I mean I don't have the sim card slot at all.

No need to cut something.. just don't close sim look on slot ... Sim will not work and no problem.

Just buy a wifi modem ( 10$ ) and use this like wifi or hotspot from phone.

Hello everyone. I have a Hizpo S5 and I also had the black screen problem and I solved it by removing the SIM card and using an LTE/WiFi modem. Since then I haven't had any more black screens... until yesterday. I got into the car and put the mobile phone in the holder that I have right above the HU and when it started up the f*****g black screen immediately appeared. Surprised, I pressed the reset button and after the logo and animation there was no longer a black screen, but instead a white screen appeared. Then I decided to remove the mobile phone from the holder and reset the HU again. It booted up smoothly and everything worked as usual.

IMO, the problem is that the antenna of the internal modem (or any other device that is very close) produces interference in some component of the HU and causes the black/white screen.
[Android Head-Units] IamPickleRick:
I tried but it didn't solve the problem. I ended up cutting the red wire. Since then, I haven't experienced any issues with the display. 🤞

Now, I'm pondering whether it's possible to reconfigure the buttons on the steering wheel. I found 2 apps, but I've had no luck getting them to work. They don't seem to respond to any changes, and nothing happens.

Has anyone successfully reconfigured the steering wheel buttons, or does anyone know of a reliable method or app to achieve this?
[Android Head-Units] MauriBixio:
Do you have canbus in car, and did you receive a canbus decoder suitable for you car with the radio?

If yes, then have to set the canbus of car, in the radio, we have talked about it decades of times...

Conversely, if you DO NOT have canbus, and use the resistive controls with the radio (via the 2 "KEY" wires in the main connector) must map the buttons on the steering wheel with the radio specific SWC app.

Other different apps won't work...

I wish I had found this site earlier... Hi everybody, I'm about to receive an Ossuret S8 and reading this topic I've discovered a couple of frankly annoying problems (such as the 4G sim one...), unfortunately it was the model that would fit best in my old VW Passat 2007 and that convinced me to take a chance on it. Anyway, I've read extensively this topic but I still have a couple of doubts that I'd like to solve before installing the unit:

- my car doesn't have remote buttons on the steering wheel nor board computer or anything else on the technological side, should I install the canbus module that comes with the HU anyway?

- according to the vendor the S8 is in theory a plug and play unit and I'd be able to install it myself, but I've read around several people experimenting battery drainage; what would you suggest? Professional installation? Taking a chance and do it yourself (and of course switch off the standby function which seems to be one of the main causes of drainage)?
[Android Head-Units] IamPickleRick:
I do have canbus and the decoder in my car, and the steering wheel buttons are functioning as they should. I would like to reprogram these buttons to perform different functions, eg. long press for siri in carplay.
[Android Head-Units] MauriBixio:
Long press doesn't work only simple press work... and the buttons on the steering wheel don't seem to be programmable for functions other than those enabled and predefined as default (buttons managed via canbus decoder).

I'm sorry to post such a silly newcomer question. I'm looking at a head unit for my car (BMW E70 X5) and found one advertised with a 7862S. I asked the seller and they said it's MTK, not FYT, which I'm guessing is Microntek? Does that fit into this thread at this point?

https://www.aliexpress.us/item/3256805889521567.html

Also, since 6GB is supposedly the max this chipset can use, does that mean opting for 8GB of RAM is pointless?

Hello all, can you please help me with one silly problem with my S5 unit?

I'm on the latest FW (QF01 from 10/2023) and MCU (QF03).

I have front DVR camera connected to AUX video input 1 and rear DVR camera connected to AUX video input 2. Before I did mess up something in settings, I was able to have both front and rear camera "app" available in app menu, but now I see only "right camera". I'm not sure what I changed, can you give some hint how to get it back? I did a FW update recently to also clear the settings but that didn't help.

Thanks

//EDIT: ok, got it somewhat running, I have now a "front camera" and a "right camera" - whatever that means, but it correctly displays video input from my front and rear cameras. I believe the front view got enabled when I switched on/off the option to display front view for 5 seconds after being in reverse, and for the "right camera", there is a switch to change that between AUX mode and the "right camera" mode, in the same settings page I believe.

This may be a stupid question, but... yesterday I was testing the unit and connected it to the hotspot of my iPhone, which works by default at 5 GHz. The HU didn't see the hotspot, so I had to select "optimize compatibility" on the phone tu use the hotspot at 2,5 GHz. My guess is that by default the HU works on 2,5 GHz frequency only, how can I enable both frequencies?

Hi and welcome,

I have an Golf MK V from 2008 and also do not have steering wheel control or such. It came with an aftermarket 1 DIN radio/cd and has dedicated ISO power connections parallell to the quadlock.

I tested canbus but finally didn't connect canbus because it doesn't provide any additional value for my car configuration. I know my fuel consumption, when my fuel is running out or if the hood or trunk is open via my board computer etc etc. I don't need that info double on a fancy full colour screen... BTW, your Passat should have an board computer as it is the same generation VW of my Golf...

And as I don't use canbus my unit shuts off completely because I used the dedicated power connections for aftermarket units as this was available. That way I never will have to worry about battery drain and the unit boots quite quick so that is no issue either...

In general you can install it yourself. Did your Passat come with an VW radio system or an aftermarket radio/cd? Chance is when it had an aftermarket unit that you also will have the extra dedicated ISO power connection and can bypass quadlock and skip canbus.

I connect over hotspot to phone for internet. I wisely never tried the 4G Sim extension. I also had to restrict to 2,4 Ghz band. My phone is an Moto(rola) btw. Internet works well, never have issues. So this is no real problem. I only use internet connection for navigating or audio streaming.

Direct wifi connection to my home wifi network does work on dual band.

Nearly a year with my unit and all in all very satisfied with it for that price. An comparable VW unit would have cost me 4 times the price and would not be as flexible/open/tweakable.
[Android Head-Units] tkktkk:
Yes I finally did today after 2 months of troubles :) ..

First, seller claimed updating head unit would solve it, that did of course not solve the problem.

Then seller sent me new screen, after mounting it, screen was all black as for some other users in this forum ( but I could here sound from the radio).

Finally today seller sent me screen firmware update, that made the old screen all black, but after mounting the new screen all works as it should long time ago, no issues with sim card and 4G!

Please note, pin layout of flat cable connection for new screen is different from old, so it needs to be as attached (witch it is by default with the screen i got).
[Android Head-Units] jokex:
Does that mean, you got other hardware and a special software-file?
[Android Head-Units] tkktkk:
Yes exactly, new version of hardware and screen firmware that is not compatible with original / old screen.

WD09... Is the new screen.

But software / screen firmware was sent after I asked for it and suggested it may be needed 😉
[Android Head-Units] MauriBixio:
Please, upload the files they sent you for the new screen, I would like to understand what it is, since some time ago Hizpo sent me a new screen (which I still have to install) to understand if this one has greater brightness than my default one screen

QLED of S8 unit.

What unit do you have?

Do these files ONLY update the hardware part of the screen?

Brightness of your new screen?

My new screen is the one in picture.

This NO have touch panel on top...only display.
[Android Head-Units] tkktkk:
Sure, but be WARNED !!, it's not for every screen as my old screen was all black after this update.

I have the "

WD090HBM30AC SO

7705 G5 D

14

+B88AA23081108038#2" screen as you can see in my previous post.

My unit is S8 from hizpo.

Upgrade instructions:

"Upgrade: unzip and copy the QF folder to the root directory of the formatted USB flash drive, plug it into the USB cable after the machine is fully powered on, the machine will automatically restart and upgrade after it detects the USB flash drive file, do not power off or other operations during the upgrade process, the upgrade will take about 2 minutes or so, and it will automatically enter the main interface after the upgrade is finished. If the machine does not upgrade action, change another USB port to try. Do not turn off the machine, power off or other operations during the upgrade process."

I did update on my old screen and got black screen after, until i changed it to the new one.

In the file itself (if you edit it) you can see for what screens it is, but SAFEST would be to ask your seller for "screen firmware".

Regarding brightness i cant say yet if the brightness is different, for now, I'm just happy sim card / 4G finally works :)
[Android Head-Units] MasterOfLight:
ok, that makes sense maybe. I got the same screen with the same issue. but I didn't get the screen firmware. so I gave up. I will try again, thanks!!
[Android Head-Units] tkktkk:
Defiantly it's worth a try, and if you have the same new screen as I, it should finally work as for me, just make sure to use flat cables from the new screen as they where provided ( do not use cables from old screen).

And I was also ready to give up ;-) But now I can put all this to rest and maybe focus on some new project, like adding a subwoofer :)
[Android Head-Units] Pingone:
Looks pretty good, hu? :)

Now I'm a bit puzzled about the data sim: the head unit detects the sim, the icon 4G appears in the head bar but I have no internet access. The sim has no password, the APN seems correct (mobile.vodafone.it) but no way... any suggestions?
[Android Head-Units] MauriBixio:
Thanks, I'll look at the files.

I don't have any black screen problems with my S8 (native QF01), never had... I'm curious to see the files, but I don't intend to flash with these.

Eventually when I feel like it (and have time...) I will try to replace only the screen, even if I don't think anything will change compared to the current one as default.

All this just to see if this new one (by Hizpo) has greater brightness... ;)
