Exactly the same car and construction year here, formerly with RCD300, now with S2-HU and rise-CANbus-box.

I don't receive AC-control either, open-door-popup-windows is the only information I get spooled to the HU.
[Android Head-Units] sniclman:
This is common problem of CANBUS decoders. Simply, canbus box have firmware which can not decode information like AC settings, door open, steering wheel controls, etc...

In my case (Opel Astra H GTC 2007) canbus decoder only decode information from steering wheel control.

Same headunit used in Škoda Octavia 2 with different canbus decoder is able decode informations about opened doors and steering wheel control.

Some user claim that AC control work, if i remember correctly they was Audi owners.
[Android Head-Units] MauriBixio:
Yes, the firmware of these canbus decoders is VERY VERY basic... for example with BMW cars they work:

steering wheel controls, open door pop-up, automatic switch to detect rear camera, external temperature, parking sensor (only if OEM BMW) front and rear.

But they don't work:

A/C climatic control, and no information relating to fuel consumption, water temperature, oil temperature etc..

All this depends ONLY on the canbus decoder of the radio, and not on the canbus of the car, which instead would show dozens and dozens of information available.

The Chinese still have to work A LOT on the firmware of their canbus decoders!
[Android Head-Units] Mr.TT_NZ:
Re canbus:

Canbus is a communication network within the vehicle; Controller Area Network bus.

The box is not the canbus, it is an interface to allow the radio to communicate on the vehicle's canbus.

Some vehicle manufacturers (and I know BMW is one) use TWO can buses for different parts of the vehicle's functions so not all data is available on any single one. I do not know if any of the canbus interface boxes supplied for use with these radios have input connections for both buses and installation would likely require splicing into the vehicle looms to gain access.
[Android Head-Units] MauriBixio:
Of course... in my post above I "simplified" to make things easier for everyone to understand.

The Chinese decoder interfaces of these radios are NOT able to decode all possible Canbus ID addresses, they have "studied" to implement the ID addresses, for the greatest number of cars/brands, at least for the steering wheel controls or little more .

You could use a canbus sniffer to detect other things and implement them in the firmware...but the Chinese certainly can't (or want) to do this for every car/brand.

So...let's settle!

Hi everyone, does anyone know if we can install this https://github.com/KswCarProject/KswPLauncher on our HU's Android or it is a special built Android?

Regards,
[Android Head-Units] marioti:
this is for completely different unit based on Snapdragon CPU, and FYT structure
[Android Head-Units] ptuchik:
Thank you for clarification, and can you please explain what is the FYT structure? Sorry for newbie question
[Android Head-Units] marioti:
FYT is the manufacturer of software and hardware (whole platform) to serve android based units. They are one of the first who popularized android system in cars.
[Android Head-Units] ptuchik:
Got you, thanks a lot
[Android Head-Units] meha576:
I just got my S8 and did a few tests like this on the table, unfortunately I don't have a GPS signal and I don't have a sound system, but for now I'm satisfied everything works, the phone connects to ZLINK and I set the boot logo of Mercedes and the boot animation of Mercedes. Tomorrow it will be installed in the car, I hope the rest will be fine.
[Android Head-Units] lucky_lucyan:
I changed the wheels and the TPMS sensor appears, does anyone know how I can solve it?

I can't find wheel recalibration anywhere in the menu, in the original unit I had it in the menu, but I can't find it in the new HU.
[Android Head-Units] meha576:
Hello. Can I uninstall the iGO application that came with the device and install my own, which works better.
[Android Head-Units] Mr.TT_NZ:
When I updated to the 20231110 firmware iGO disappeared and was replaced by Here maps. Looks much better. Otherwise download Magic Earth app (my favourite) from either the play store or the Uptodown site and install. Both of those you can download entire maps into your unit so they can be used without an internet connection for navigation. No live data of course without internet.
[Android Head-Units] MauriBixio:
Sure, you can do it.
[Android Head-Units] PrinceLc:
Hello to all do we have the ability to access the backcam during the drive ? Thanks
[Android Head-Units] MauriBixio:
No, the trigger for Back cam occurs through reverse input.

Maybe you could (if you want to have MANUAL activation INSTEAD of automatic and use dedicated AUX stock app) use AUX input instead of dedicated Back cam input, and so you can view the images from the rear through Back cam, but you would lose the automatic function through reverse gear .
[Android Head-Units] PrinceLc:
Ok but I had a Junsun with an Helio P22 CPU there was an option for this only this unit had this option. The thing is that my cam is always active on ignition on. But thanks for the answer
[Android Head-Units] PrinceLc:
Hi I updated to the latest firmware and MCU now ZLink is gone someone a tip to get it back ? The firmware is for the S7 Modell
[Android Head-Units] atifarkas:
Hi! I have s6 in Peugeot 508, everything are working fine, original reverse camera, parking sensors, etc. But how can i share my pixel 6 phone internet via Bluetooth to the car hu? On my phone I enabled the internet sharing via Bluetooth, but the network profile is not visible in the connected Bluetooth HU page, near others like contacts, hd audio, media audio, headset, etc.
[Android Head-Units] marioti:
no, only wifi tethering
[Android Head-Units] PrinceLc:
Hello someone please 🥺
[Android Head-Units] PrinceLc:
I think in the last firmware there is an option for Bluetooth teether but I am not 100% sure
[Android Head-Units] MauriBixio:
About this Sunon silent fan?

By Ali good price:

https://it.aliexpress.com/i/1005002565155015.html
[Android Head-Units] Bro´:
I replaced the original fan with this one and I must say that it is not a fundamental improvement. It is neither quieter nor cools better. As an alternative, I am considering replacing it with another quieter one before the summer, although I will have to adjust the wiring. For example something from Noctua.

Don't really expect a miracle with this one.
[Android Head-Units] PrinceLc:
Good morning or evening to all I have a problem that sometimes the screen goes black and sound is playing normal. I asked Ossuret and they told me to take away the SIM card! Someone with same behaviour? It's fixed without SIM ? Sorry for asking when it's mentioned already. I have the S7 model with 6 Gig ram and the latest firmware from October. Thanks
[Android Head-Units] MauriBixio:
Question asked dozens of times now...just read back in the forum for the "solution", even if it's not the final one.

Someone cuts a cable from the SIM connector, but I don't remember...

Frequent problem for those who have the new native mainboard with MCU QF03.
[Android Head-Units] PrinceLc:
Ok thanks
[Android Head-Units] Lione2:
Already got the problem, i had to update it again with clear user data checked
[Android Head-Units] wanxu:
Guys, did you change somehow the resolution? For Spotify for instance, everything is so small that's hard to manage on a car touchscreen.
[Android Head-Units] PrinceLc:
Yes did the same thanks
[Android Head-Units] PrinceLc:
Yes did it bit than maps in widget is mismatched not aligned
[Android Head-Units] PrinceLc:
Another question on the latest firmware from Nov it's normal that when you change launcher or something in Factory menu the device reboots to take changes ? On August firmware that was not so.
[Android Head-Units] MauriBixio:
@marioti

I accidentally deleted my stored address book from my phone from the radio.

Now I can no longer download it from my phone to the radio, for no apparent reason it can't.....in the meantime I haven't changed anything on the radio, this is all strange.

I seem to remember that you know how to solve this problem...or am I wrong?

I use the latest firmware from October, the official one with changelog, and after installing it some time ago this address book problem did not exist, the transfer of my contacts from phone to radio via BT happened without problems...

Thank you
[Android Head-Units] marioti:
i don't think i had this kind of issue. But try to reset bt (there is a reset button i BT app, in the last tab, or so), and clear (delete) all paired devices. Then pair the phone again and during pairing allow it to take your contact list
[Android Head-Units] MauriBixio:
SOLVED:

- Phone settings

-Select the paired BT devices

-Select the Sx radio from the peripherals

-Enable the Personal Contacts sharing option

After this the radio will download the personal Contacts from the phone via BT.
[Android Head-Units] jokex:
Problem for me appears every time when updating without deleting personal data. After another update that way ZLink is back working.
[Android Head-Units] jokex:
If the device is rather new try to contact the seller to have a replacement. That was the final solution for me.
[Android Head-Units] PrinceLc:
QF03 device mounted on Friday last week was 2 times only first time using ZLink white screen second using DABZ Black screen, the whole weekend all Fine SIM still in the unit
[Android Head-Units] PrinceLc:
What about the new firmware where you must reboot to take Effekt of changing Factory settings or eg Launcher change ? Normal or is it a hiccup on my side ?
[Android Head-Units] Matteo F.:
HI,

you can enable tethering via bluetooth by entering config menu and set to "open" the last option: Using the phone's Bluetooth shared network.

When connected to the phone, if the connection is shared, the bluetooth icon on top of the screen will change showing two "network" symbols on the right.
[Android Head-Units] PrinceLc:
Is someone on October firmware? Got it from Ossuret
[Android Head-Units] Astralech:
I also had a restart after each change in the factory options.
[Android Head-Units] atifarkas:
This menu item is missing. I asked hizpo, they said i have to enable the Bluetooth two-way transmission in factory settings 8888. But this option also missing. Tried to enable dual bluetooth with 20231006 code, but nothing happened. I have qf03 mcu and 20230824 system version. Someone know how to enable dual or two-way Bluetooth?
[Android Head-Units] Barykelo:
Why is it that you don't have this item there? Update the firmware!
[Android Head-Units] PrinceLc:
Info no black screen anymore with SIM! Hope it will still so
[Android Head-Units] PrinceLc:
Changing launcher too ?
[Android Head-Units] inscriber:
On this device no, but on my previously android I use something like DPI changer from playstore. Can't remember exact name but you will find something similar.
[Android Head-Units] Astralech:
If I remember correctly, after changing the Launcher there was also a restart. I was very surprised because it had never happened before.

Edition:

Today I uploaded the program from 13.10.23 and everything works as it should.
[Android Head-Units] MauriBixio:
No reboot after changing stock launchers.
[Android Head-Units] PrinceLc:
Witch firmware ??
[Android Head-Units] PrinceLc:
By the way orders screen replacement
[Android Head-Units] PrinceLc:
August firmware no reboot after change it was shipped with this.
[Android Head-Units] PrinceLc:
Flashed October firmware more stable than November and no reboot to change launcher
[Android Head-Units] PrinceLc:
So this white screen or black comes only when running ZLink. All other apps not
[Android Head-Units] PrinceLc:
Did someone have a good app for enabling the status bar with notification ?
[Android Head-Units] Greiviasd:
Anyone managed to change rotation of apps in mode button ? Since steering wheel buttons work, would be awesome to change between Zlink, torque, radio and main. Kinda useless now rotating music player, onboard navi etc.. that I dont use. "Ossuret" K706 for Audi A4 b7.

[Android Head-Units] MauriBixio:
With BMW cars the "Mode" button on the steering wheel works via canbus, and rotates the MEDIA apps of the S8 radio in succession.
[Android Head-Units] TorstenH:
I think he wants to be able to define which apps should be considered by mode button. Especially 3rd party apps from PlayStore.

AppSwitcher is even going a step further and is not only rotating:
[Android Head-Units] MauriBixio:
This is not possible to define with stock function/launcher,with MODE button.
[Android Head-Units] TorstenH:
It should be possible by setting "AppSwitcher Starter" as navigation app, configure the SWC mode button to start navigation app and configured AppSwitcher according to the log entries, the head unit writes on SWC navi key press.

[Android Head-Units] MauriBixio:
The "Mode" button on the steering wheel is not the same as the one that launches the Navigation app (which not all cars have).

MODE button switch only the stock MEDIA apps (as default), then I don't know if the MODE button can be enabled through you app anyway...
[Android Head-Units] TorstenH:
I know. But isn't it possible to remap the mode button to launch the navigation app? Or does this only work if no can box is in place?
[Android Head-Units] MauriBixio:
With BMW, MODE button works via canbus box, and essentially its function is like the default one with oem multimedia hardware, so it switches between the MEDIA apps, and does NOT run Navigation app.

With Sx radio we can assign any app (even non-stock) as a Navigation app, but this does not start afterwards from the MODE button on the steering wheel (at least in my case).
[Android Head-Units] TorstenH:
That means the SWC learning only works if no can box is in place / SWC is connected as resistance matrix?
[Android Head-Units] MauriBixio:
Through the canbus box I do not have to assign any function/button to the steering wheel manually, everything is "automatic" and pre-established, exactly like the oem function.

I don't have resistive controls, I don't use SWC stock app (I don't need it), the buttons on the steering wheel work via canbus, and the radio "decodes" them when pressed, via the included can box adapter.

You CANNOT assign them functions other than those envisaged if they work via canbus.
[Android Head-Units] MauriBixio:
Since you develop apps, I ask you:

Is it possible to FORCE the uninstallation of the "TPMS" app of these Sx radio (it is a stock app integrated into the radio firmware, so as default with the standard method it does not allow this, and what is the purpose of monitoring tire pressure via USB hardware)?

I use a similar different app for this function with my hardware, and that stock app is annoying with a popup that says "I can't work..." every time I start the radio!
[Android Head-Units] TorstenH:
If you know the package name you can deactivate it via adb command or even remove the whole apk file via adb shell.

But I'm surprised factory settings doesn't allow to switch it off.
[Android Head-Units] MauriBixio:
This should be the stock TPMS app...(I don't remember where and how I found it) but maybe it's not the latest version though.

How to uninstall or deactivate (step by step) this via ADB command directly? ;)

Edit: the firmware does not allow direct uninstall, it seems to lock this function for this app.
[Android Head-Units] TorstenH:
pm uninstall com.syt.tmps.TpmsApplication
[Android Head-Units] TorstenH:
@PrinceLc made it work by remapping a SWC button (can box in place) and setting "AppSwitcher Starter" as navigation app. Thanks for testing!
[Android Head-Units] PrinceLc:
Yes it works perfectly
[Android Head-Units] MauriBixio:
The "easiest and fastest" method to run this string?

Do you need an app for ADB wi-fi installed (on your phone or radio)?

Any suggestions... ;)
[Android Head-Units] TorstenH:
Install Remote ADB Shell from Google PlayStore on your phone.

Open hotspot on phone and connect the head unit to it. Run Remote ADB Shell on phone and enter the ip of your head unit (port 9876).
[Android Head-Units] MauriBixio:
So you say that he remapped the "MEDIA" button on the steering wheel (with canbus decoder connected) via SWC stock app, assigning YOU app as Navigation app to the "MEDIA" button on the steering wheel?

I don't think it's possible to do, at least with BMW.

I would like to point out that there are different versions of Canbus decoders and manufacturers for these radios, but with EVERY car model/brand you must use the suitable one, with different settings, so it is possible that it is not a universal situation...

Furthermore, these canbus decoders are really basic, the steering wheel controls work or little more, depending on the car brand/model...
[Android Head-Units] MauriBixio:
Thanks for the suggestion!

In the next few days I will try your solution, if "I don't succeed" I will contact you if necessary. :D
[Android Head-Units] TorstenH:
I'm sure @PrinceLc will show us how he remapped the button. He used another SWC button, but it should be possible with every button.
[Android Head-Units] PrinceLc:
My car a Passat b7 with Reise ccanbus decoder I can change the SWC to any

[Android Head-Units] RightIsWrong757:
I did an upgrade with software provided from the seller of my unit (MCU and firrmware) and it seems to have broken a few items that are severely hampering my user experience:

1. Double tapping on the home screen car widget (shown on lefthand side of screencap) no longer opens navigation, like it did in the previous version.

2. The weather app is not activated and I do not get the option to even try to activate it. If I open the weather app itself, I receive an error (Activation code error)

3. When I open the GPS app and then click the home button, the map is minimized and no longer shows on the homescreen within the area where the car widget is, like it did in the previous build (PIP does not appear to be working)

So far, the vendor has tried, but has been unsuccessful in their fixes. Has anyone else had this issue and, if so, is there a fix? Should I try to get the original build and roll it back?

Any help would be appreciated.

I am aware there are newer firmware versions out there, but besides having issues with file managers and USB, everything else is working properly.

For me it sounds like a little hack... maybe the app developers are using a dedicated WLAN connection to identify if they are in their own environment to bypass the app registration.
