Canbus error VW PQ (etc) SWC Voice Assistant Button

Slavus

What are the differences between Canbus VW-RZ-08 and G-RZ-VW58? I have RZ-08, but i see on the pictures with Software Info, that RZ-VW58 is shown as RZ-08, are they the same Canbuses?

your application is for carlink, not for climate control... After installation my android auto has connected... should be nothing to do with that...?

I tried to update CANBUS with your file, but after selecting it from HU memory and clicking START, I only see a warning, I confirm and nothing happens. I saw on various forums that the update is done from USB memory, not internal, but when selecting the file, there is no option to select USB. Is this update file for all Raise G-RZ-VW58? This is my version.

dudu-lai

Slavus Yes, CANBUS update selects internal storage

Slavus

dudu-lai i can't update with your file, nothing happens after start, only warning, i click OK, then nothing.
This is my CANBUS

i have a similar issue where the voice button on the steering wheel is not working, this should engage google assistant , it works only while in the home page dudu7 but in android auto is not launching the assistant, instead it is activating on my phone. any ideas on how to change this behavior so the assistant activates on the headunit instead?

When trying to update, CANBUS operation is blocked, no response to pressing the steering wheel buttons. The attempt was unsuccessful, as I wrote earlier, additionally, after updating to version 3.6 beta3, the device cannot be restarted, this can only be done via the "recovery" button on the system information screen. I also tried updating Canbus on Mekede M600s, the effect is the same, i.e. no effect 😉 below is a link with a recording of the update attempt

Slavus Are the air conditioning controls and door messages working?

Slavus

Slavus finally i bought another Raise G-RZ-VW58 with 2402 production date and upgrade ends succesful, Voice Commands starts with SWC buttton

Slavus

dudu-lai Everything works, CANBUS is blocked only when the update application is enabled. Then you can't even reset the HU, except the way you see in the video. After restarting it's fine again.

Request for Compatible Firmware/MCU Update – UIS8581A Android 14 with CAN-BUS Issue

Dear Support Team,

I am reaching out to request your assistance regarding a CAN-BUS compatibility issue that occurred after updating my head unit to Android 14. Since the update, the system no longer recognizes the CAN-BUS module of my vehicle (VW/Skoda/Seat), and the unit does not power off automatically when I turn off the ignition.

Below are the technical details of my system, so you can verify compatibility and provide any necessary firmware, MCU update, or configuration files to restore proper operation:

⸻

System Information:
• Android Version: 14
• RAM: 8 GB
• ROM: 128 GB
• CPU: 8 cores
• System Platform: UIS8581A
• CAN Version: Raise > VW/Skoda/Seat > VW-SKODA_R01
• CAN Info Version: 24.0.1.20250430
• System Build: ZA_2025.02.26.12_6_6826
• MCU Version: ZA001-23.12.22_409

⸻

Issues encountered after the update:
1. The system no longer recognizes the CAN-BUS module (no steering wheel controls, door/lighting data, etc.).
2. The unit does not shut down automatically when the car is turned off.
3. All CAN-BUS functionality was working properly before updating to Android 14.

Please kindly provide:
• A compatible version of Android 14 firmware or ROM that fully supports my current CAN-BUS configuration.
• Or, an updated MCU version that restores CAN-BUS communication.
• Alternatively, a stable previous Android version (12 or 13) that ensures full CAN-BUS functionality.

I would greatly appreciate your support in resolving this issue. Looking forward to your response and any download links or instructions you can provide.

Tiadescau Please contact your seller, this has nothing to do with DUDU, DUDU 8581 is Android 10 and has never been updated. We are unable to help.

Tiadescau If you want to properly solve this, buy a Dudu unit. Yours is an entirely different platform, probably with fake Android 14...

Tiadescau

It’s a Raise can-bus decoder
And have the same problem, before, only work well the track < > and volumen control of the steering wheel, the microphone button active the mute.
However, after updating to Android 14 while using wireless mode, the CAN bus ceased functioning entirely.
The android 14 no it’s false

JhonnyD

Tiadescau How did you update to Android 14? DUDU OS for your CPU is Android 10.
You just can't install DUDU OS if you really have Android 14.
So talk to your seller.

Tiadescau

Can you send me the last version to Raise decoder VW 2018 models please?

Hi everyone,

Sorry if this isn’t the right section, but this seems to be the only place where people really understand these systems.

I recently installed an Android multimedia head unit in my VW T6, purchased from the Navirelax Franchised Store on AliExpress. Everything worked fine at first. However, after updating the system to Android 14, and using it in wireless mode, the CAN bus stopped working completely.

Now I’ve lost all CAN-related functions: steering wheel controls, parking sensors, vehicle info, etc.

The seller is unresponsive or doesn’t seem to understand the issue when they do reply. I’ve tried checking CAN settings in the factory menu, but nothing seems to fix the problem.

If anyone has experienced this, or knows where I could find:
• A working firmware (or a downgrade to Android 13)
• The correct CAN protocol configuration for the VW T6
• Or even a trustworthy support service in Europe

…I’d be truly grateful. I’ve searched everywhere online and can’t find solid support.

Thanks so much in advance!

Tiadescau …I’d be truly grateful. I’ve searched everywhere online and can’t find solid support.

Search (Google) for "MCU ZA001" and you'll find a thread on XDA discussing your unit. Read that thread, then ask your question there.
