I had some problems with the carapp crashing and received the following from the seller.

For saving the log file to a USB stick, you need code 1212. (sure have the file send to them after it)

----

Steps to catch log: 1. Insert the USB flash disk, 2. Open the "Car Settings" app, click "Factory Settings", and enter the password 8888, 3. Find item 30 "save log switch" and turn it on, 4. Find ways to reproduce the problem, 5. After the problem reappears, enter 1212 again in the "Factory Settings" menu just now, 6. Log will be automatically copied to USB flash disk

----

Do not know if it is helpful for others :-)

@janolelapin The additional "firmware" thread is only used as an overview of shared firmware/mcu versions. See the first post in that thread please.
[Android Head-Units] Flaming_Star:
Thanks for this Thread and all the firmware so far. There are a lot of interesting informations for me.

I have a problem with my S8. I can't start Google Assistant with "Hey Google". Is it necessary to have Toppal or the paid version of Toppal?
[Android Head-Units] Clyde72:
Hi, I use Google Assistant in stead of Toppal but Voice Activation isn't possible. Maybe possible if one would get GA service running in the background (still to try 🤔🤔). Maybe similar for GA floating balloon...

I placed the GA button on my launcher and tap if I want to use it.
[Android Head-Units] Flaming_Star:
Thank you, thats a good workaround!

Hi, bought the device directly from Jitu, I think they produce the device. When I try to connect wireless CarPlay, Bluetooth connects and it keeps on loading, anyone face this issue? Also, is there a new firmware version. Check screenshot for system info
[Android Head-Units] blue_one:
Welcome to the show! Jitu is indeed the original manufacturer. I use the Carletter app for wireless android which works flawless. As far as i know you can switch between Carletter and Zlink. Maybe you try around a bit.

Cheers,

blue_one
[Android Head-Units] shammeel:
Thank you, how do I switch to Zlink?
[Android Head-Units] blue_one:
I haven´t had a look into that yet. It was mentioned in one of the firmware release notes that it is possible to switch. Next time i´m in my car i will have a look. ;)

Just for my own curiosity: how much did you pay at Jitu directly?
[Android Head-Units] shammeel:
$145 8GB/128, thank you please do.
[Android Head-Units] shammeel:
How did you switch to Zlink?
[Android Head-Units] fjavierb:
Hola.

para seleccionar el zlink, en mi radio s8 tienes que ir al menu oculto (8888), y en la ultima opcion de la lista te deja elegir entre carletter y zlink, una vez seleccionado hace que reinicies, puede que te pida activar eso.
[Android Head-Units] Clyde72:
That's without VAT I presume

Can you take a photo of the backlight IC chip (high resolution photo) and nearby components of the 10" unit?

Exact code that is written on that chip?

And...Hizpo sent me a new 9" display for my S8 some time ago, code:

WD090HBM30AC-SO-50

So is it the same as you,? (in mine I also have the additional acronym "SO")

Hello

I have roco s6 and I experienced "stupid" issue like missing documentsui.apk.

Without this app, other apps what require this ap just show error.

If I installed it (downloaded from apkmirror) sometimes works sometimes getting an error.

Any suggestion how to solve it?

Thanks in advance
[Android Head-Units] Barykelo:
you are right, there is always -SO, supplemented
[Android Head-Units] Barykelo:
reinstalling the firmware won't help?
[Android Head-Units] Mr.TT_NZ:
The3 new S2 I ordered recently turned up yesterday, the brightness seems fine and the display has the code

WD070GBM30AE-N7

Just to add to the list of type codes.

Additionally it was missing the shield over the radio chip (I made one and fitted it) and the heat transfer pad for the processor was too thin to make contact between the heatsink and the chip. I've added a layer of transfer pad which was previously used to mount a power transistor in another piece of equipment.

The previous one I got at the end of last year was correct so the assembly quality has dropped somewhat.
[Android Head-Units] cocoamba:
I asked the seller whats is the changelog for 01.2024 update and below you can find the answer:

2024-01-05 (v2.90) Update Notes.

1. Change Android version to Android 13.

2. Solve the problem that the Android version of Fake Device Test, Device Info HW, Geekbench and other APPs shows Android 10.

3. Simple can be activated automatically by connecting to the Internet.

4. Add wireless Hicar support

5. Solve the problem of high temperature DDR initialization failure.

6. update peer weather, adapt to 2000*1200 and other different resolutions

7. Solve the problem of no sound of Bluetooth phone after TMAP navigation is opened.

8. optimize 360 panorama function

9. Solve the problem that sometimes the saved touch learning is invalid.

10. Removed the OTA upgrade function of Peer to Peer.

When asked if there is a newer MCU version than mine (picture attached) they said no.
[Android Head-Units] Tchutte:
Anyone?
[Android Head-Units] PrinceLc:
Yes documentsui is missing that is sadly only with root we can maybe implement it again but we need the singing private key. For reading and writing to usb with third party apps use Mixplorer and activate custom usb OTG Driver in settings

If only have an email to the producer....

Is it difficult to root this radio?
[Android Head-Units] PrinceLc:
We try to figure out how to root with Magisk the radio is rooted but only root with ADB Shell
[Android Head-Units] PrinceLc:
I wrote to ossuret too that documentsui is missing and the notification bar too
[Android Head-Units] Barykelo:

[Android Head-Units] Tchutte:

[Android Head-Units] PrinceLc:
No you don't damage
[Android Head-Units] dzikk:
Notification bar it was first what I reported to seller. So I believe in You if you will find a solution to root this radio and bring back main functions of android... My previous radio with android 8.1go ( android 6) has better firmware than this one.
[Android Head-Units] MauriBixio:
S2 does not have a QLED display but IPS (so they specify).

Only S5-S8 (if I remember correctly, S8 definitely have QLED) even if we have to understand if it is a REAL QLED, which doubt very much, since I have S8 but brightness is low, and the colors are NOT of a real QLED display.. .
[Android Head-Units] PrinceLc:
Come to QF001 chat on telegram
[Android Head-Units] MauriBixio:
I'll investigate...then I'll let you know.
[Android Head-Units] MauriBixio:
Well..from your photo (since we don't have an electrical schematic of the mainboard PCB) I deduced:

On board there is no TRUE IC controller chip dedicated for the power supply stage (PWM) for the display backlight.

The complete stadium is the one I highlighted with a red rectangle in the photo.

What I highlighted with the cyan arrow is a power mosfet, which delivers the maximum current to the final backlight stage, the "most important" component of the entire stage.

The ones I highlighted in green are 2 common transistors (NPN or PNP, I can't know without the electrical schematic) which together the 2 gray inductors (which I highlighted in purple) and the rectifier diode (which I highlighted in yellow) create the main stage of the backlight.

All other SMD components are ceramic resistors and capacitors, which serve to terminate the backlight stage.
[Android Head-Units] Vampire_Dracula:
I tried Navradio+ on my Ossuret S8. While I liked having those nice logos for each station, unfortunately, the app is unusable for me. The audio has gaps caused by the navigation voice guidance, even when I mute the audio guidance.

I discovered the bug too late for an automatic refund, but the developer agreed to refund me, after saying that there is nothing he can do about it.
[Android Head-Units] Barykelo:
Can you explain this further? The translator translated it strangely for me.
[Android Head-Units] Vampire_Dracula:
When I use Navradio+ together with the Google Maps navigation, the music is interrupted when Google Maps is talking.

The interruptions are even happening when I mute the voice guidance in Google Maps.

I've been told to reset the Bluetooth connections, to install the latest firmware, but nothing helped.

Very annoying. Unusable.
[Android Head-Units] Tchutte:
It was indeed the red cable. Sound works.

I still have a issue with the reverse camara. I contacted the supplier. Probaly power problem.

Still 3 questions,

1. Where is the fan control settings?

2. I cant download netflix in the playstore, is that normal?

3. When a song plays and the sound is low i hear a low noice, is that normal?
[Android Head-Units] Barykelo:
You're right. The radio sound is first muted and then cut off.
[Android Head-Units] Ferike57:
Thanks for the help!Ferenc
[Android Head-Units] cocoamba:
What is your issue with reverse camera?

For external amplifier you can use the blue wire (antenna 12V+) wire or the red wire (ignition 12V+) as a remote wire. I recommend the blue antenna wire because it is only active and has 12V current on it while the navi is ON and working. The red iginition wire has 12V on it every time the car's key is on ignition position so the amp will work even if the navi is dead/not connected etc). I explained all of it a few posts/pages back.

The fan control is in an app - fan control I think it's called. You must connect the fan's wire to the proper wire in the wiring harness (in my navi it's the wire harness that has the 4g sim slot on it).

I tried to install netflix on an older navi and I couldn't because either google play or netflix itself couldn't identify the device (probably ot wants to know what device you are using in order to apply the correct settings (e.g. resolution etc). I don't think you will be able to install it.

What kind of noise are you hearing?
[Android Head-Units] PrinceLc:
For netflix download the apk via apkmirror or so then all works normal, it's not on PlayStore available because the device is not certified by Google.
[Android Head-Units] Tchutte:
The oem camera wont show up. Maybe a setting? Or no power?

Netflix works thx.

Fan control works.

The noice that i hear is a soft sssss noice. When the amp has power. If i play no song a couple of seconds later the ssss sound is gone.
[Android Head-Units] colestium:
I have issues with the S5 (6gb/64gb 4G). Multimedia need circa 30 minutes to start normal. In this first minutes multimedia restart and stucking at "powered by android" or "scrolling android logo". After this circa 30 minutes self restarting, when is finally start multimedia works normal. I was try hard reset and upadte firmware without luck. Then I was connect multimedia on laboratory power supply same problem. Can someone give me instructions which components to check on the motherboard with a multimeter? or any help.
[Android Head-Units] cocoamba:
For the rear camera to work you need to connect it to the navi unit. In order to do this you must connect the rca cable that comes from the camera to the proper rca in from the navi unit and also provide 12v+ signal current from the camera's 12v+ wire to the navi unit pink 12v+ wire (camera power signal input).

In the first picture you will see the video input = yellow rca (you have to feed video signal to it from the rear camera via a rca cable) and the pink wire from the main wire harness which is the 12v+ input from the rear camera. There you should connect the power input from the rear camera and feed 12v+ when you are in reverse mode.

To be more clear: rca video cable from camera to navi is always on but the camera turns up and sends video signal to the navi only when it is powered. This start-up signal (12v+ current) must also reach the navi in order for it to know "when to switch to and show the rear camera on your screen". This is made in an aftermarket rear camera by feeding 12v+ into it from reverse lights (they turn on once you put the car into reverse and stop afterwards). You can see the basic scheme in picture no. 2. I don't know how your oem rear camera is but if you want to connect it to the navi unit you need to have rca video signal cable and 12v+ signal when in reverse. If your oem rear camera has rca video cable then just connect it to the video input yellow rca on the navi unit. Otherwise try to find an adapter from whatever wires you have to rca. If your oem rear camera outputs 12v+ then feed it to the pink cable of the navi unit as explained above. If your oem rear camera dosen't have this 12v+ wire then you can feed the 12v+ input wire of the navi unit (the pink wire) with 12v+ from your rear lights lamp (find the reverse lamp, find it's 12v+ wire with a multimeter and connect to it to be able to send 12v+ signal in the front of the car to your navi unit).

If you already did all the above and you are certain that you have both video and power signal, both of them correctly connected, then try to adjust the rear camera settings. Go to device settings / factory settings / use code 8888 / rear camera settings and here change the camera mode from ntsc to pal to others until you find the right one.

Please confirm once you have solved your problem.

I see it's getting HOT in here..more and more victims of this 'great' device.

Anyway im still strugling with 4G/LTE connection.​

It takes ages to start working, and i found interesting stuff!! Internet works!! But if not using domain names!! So this means device blocks DNS port (53) so applications can not work if using domain names instead of IP. ANy application that uses itnernet based on ip, lets say PING app -works ok! I saw some tiny_firewall in system folder, it blocks 53 port. I deleted that **** [and some others like spyware Topal..] Did not help. Funny fact -wifi always works good, 4G works sometimes and only after some period of time. Signal here is NOT important. SOmething else going on. People who have 4G versions, do you also have to wait some minutes so internet via modem to work properly?? I see data arrows near 4G icon they show communication, but as i said DNS based queries not resolved.
[Android Head-Units] cocoamba:
Mine works perfectly with 4g or h+. If i reboot it once it gets to the "desktop" the internet is already connected and working in 4g. If i put it to sleep and wake the device later it is working instantly. I know that each country uses different internet bands and this devide might not be compatible with the bands used in your country. Also, normally you would haveto do the internet settings: apn, username, pass if needed, mcc, mnc etc.

I hope this helps you!

The 4G modem is designed for Chinese spectrum. It has limited compatibility with Europe and no compatibility with the US spectrum. You are much better off using your phone as a hotspot, since your phone will always maximize your operators spectrum, especially if it's a recent model.
[Android Head-Units] Tchutte:
The noise is gone. Connected it to the wrong RCA.

The reverse camera still wont work.

Here are some pics:

I have a cable below that is connected to C and to the powercable harness, that has a camera label. That one go's to the OEM connector. The same cable has a beche color cable what go's to the canbus?

What's wrong?

Here are the factory settings:
[Android Head-Units] cocoamba:
From what I can see you connected the camera input yellow rca to another yellow rca from the wire harness that is an output for something (audio, video etc.). You should feed video signal in the yellow rca directly from the rear camera and not anorher rca in the wire harness. You basically created a loop between the rca video in and another rca output, both from the same wire harness. That's why it's not working.
[Android Head-Units] MauriBixio:
These units can NOT work with oem rear cam, but only with after market rear cam, PAL or NTSC signal, and standard or AHD resolution.

If the OEM rear cam cannot be driven by simple RCA video signal, it will not work.
[Android Head-Units] kwiedo72:
In my car ford f150 it works with the OEM camera, picture quality is not great, but it works
[Android Head-Units] ScorpionSX:
OEM rear camera should be possible on these units, either right away via CANBUS decoder, or there are also conversion harnesses available for some models, I saw some on Aliexpress, you will plug that in between the OEM radio wiring and the aftermarket radio wiring and then you will have also a cinch cable going to the radio connector, so the camera would work. Not sure about the quality though...it may very well be crappy, I can't speak from experience here.
[Android Head-Units] Tchutte:
I used CAM IN with camera:

I have these cables:
[Android Head-Units] MauriBixio:
Sure, ONLY if the oem camera works WITHOUT oem hardware for oem multimedia system, then, in this case, it could work ONLY via canbus and not differently with the common RCA video connection of these Rocko units.

I can assure you that for example BMW oem rear camera, with these Rocko units, does not work. However, it is possible to use the after market AHD camera in any case, without problems, and with excellent final resolution.

It is also true that the Chinese have designed specific hardware interfaces for some car brands that adapt to the car's canbus to Android radio, but they only exist for a few car brands...
[Android Head-Units] MauriBixio:
For the rear camera these units have a specific RCA video input (yellow), use that...
[Android Head-Units] Tchutte:
They sold it specific for my type car with canbus. Canbus works, except the camera.

I have multiple yellow rca cables, see the picture.

1. Camera

2. Video in 1

3. Video in 2

4. Video out
[Android Head-Units] MauriBixio:
The right input for rear camera is: "CAMERA",

If you use this input, when you engage reverse gear, it automatically switches the rear camera signal on the display, via canbus.

If it doesn't do this, and you don't see any images, check if your rear camera is compatible, if it is set correctly in the radio, and if it is connected and powered correctly.
[Android Head-Units] Vampire_Dracula:
Yes, it also worked with the OEM camera on my 2019 Honda CRV (it uses the NTSC standard). But I prefered to replace it with a 720p AHD camera. I actually bought a new OEM camera, removed from it from its bracket and I reused the bracket and OEM connector attached to it (after identifying the video and the power wires) for a non-destructive installation (no drilling new holes, no need to cut cable, no need to run new cable)

One thing I just noticed about the latest version is that 3rd party media players now show up in the homepage media widget. At least I am seeing the current song playing using Audify music player now in the widget.

The only "problem" is that I don't see the cover art, just the title/artist and the Audify logo instead of the cover art, but that's still better than not seeing the media, since the default player doesn't provide the functionality of the third party app.
