Blackbandt I think so but you'd better follow @dudu-lai request for a picture of the canbox label so that he can confirm.

dudu-lai Hello! I am using the decoder (as shown in the picture) for a Skoda Octavia 1Z3, and I have updated the firmware to version VW-RZ-08-0040.212.04-HSE, but the error codes still appear:

Is there any Raise firmware version that can emulate the radio and J401 port to clear these errors? Thank you very much.

Do you have an update file for this Raise canbus RZ-GM09 to remap swc from mute to Google assistant?

motrac No, what's the problem now?

The voice button on the steering wheel mutes the audio.
I want it to open the voice assistant.
I tried different settings for other vehicles besides mine and none of them work.

Thinhpv Updating the Canbus Decoder won't eliminate CAN bus errors in the car. I don't think there's a way to fix them through emulation, and the only option seems to be VCDS programming, I don't know. Do these errors even matter to you? I have the same issue in my VW Jetta, and I'm not worried about it at all.

Thinhpv as @Slavus mentioned, these are typical errors you see when connecting Canbus adapters. The car's diagnostic interface tries to talk to the radio/navi/information system and Canbus adapters don't answer as expected or at all, resulting in these errors.
They are harmless.
I have VCDS and have unchecked radio/Navi/information system - but then you see other errors: The radio doesn't get any info (in fact SWC often gets disabled) and the car's diagnostic interface complains about wrong coding because it sees "something" like radio / navigation at least.
So leave as is, if it works.

Slavus Thank you for the information you shared. I am now more comfortable with these error codes since the necessary display functions are still working properly.

gismo My RAISE CANBUS decoder, when updated to firmware VW-RZ-08-0040.212.04-HSE, was able to send the GPS address to the ECU during the first startup after the update, allowing it to display on the screen as shown in the picture. However, after turning off the car and restarting it, the ECU no longer receives the GPS information. Possibly, if this issue can be fixed, the error code 01300 - Control Module for Navigation with CD-Rom (J401) could be cleared.

Thinhpv Mine still sends the info. I have a VW T6 MY2019, configured as VW/PQ low.
The info will not be sent (or rather received...) if you have only Radio coded in the diagnostic interface. It needs to be radio and navigation. In VCDS I don't see Navigation with CD, only Navigation.
Alternatively to "Radio" and "Navigation" you can try "5F Informationselektronik", this was my OEM configuration but it gave me errors (wrong coding) with Android GUs so I ticked it off and enabled "Radio" and "Navigation" instead. That seems to work fine, I don't see wrong coding anymore.

Thinhpv

gismo Thank you for your information. In my VCDS, my car also only has “37 - Navigation” and “56 - Radio,” not the detailed option “Navigation with CD-Rom.” The VCDS information detecting “Navigation with CD-Rom” is probably coming from the Android Radio itself. At the moment, I still cannot output the GPS address to the ECU. I will look into other methods.

Thinhpv GPS address /coordinates are not showing in the car's MFD but in your picture it was compass info and that will show every time the car changes direction. Need to be driving and changing direction to see it, it's not permanently displayed.
