HAccord8 hey I have a CC3 too and don’t know this was possible. Do you have the link to instructions to install duduOS on the CC3?

Saburo

Hi wirezz , You can start by reading this. https://forum.dudu-auto.com/d/2559-duduos-beta-testing-expands-to-more-devices-join-now-for-portrait-mode-support

wirezz Teyesa bym nie ruszał, mam dwa systemy w dwóch różnych autach i Teyes jest bardziej niezawodny niż Dudu.

DUDUOS 2025 1104 and carlink 2.25.0926—does this ylog include the issue where SWC cannot control CarPlay to switch songs?

HAccord8

DUDU-Meng yes it does. SWC doesn't control the carplay previous/next or play-pause commands and sometimes no audio either. This only happens when device wakes up from sleep mode - to fix this a restart is required.

Anyway, like i mentioned the screen resolution issue happens with either version of CarLink app version, which is the main issue here. I can keep using version 2.25.0926.1708 which does nkt have the issue with SWC.

Again, the main issue is the screen resolution issue here when the CarLink app is used without navigation bar caused by DuduOS. Please pass this feedback to the developer

DUDU-Meng

HAccord8 Please confirm whether you pressed the steering wheel's song-switching buttons in this YLog.
The log clearly shows you only pressed the volume +/– and Home buttons.

HAccord8

DUDU-Meng yes I pressed the song switching buttons and not the volume buttons. Can we please stop and focus on the real issue which is the screen resolution issue with CarLink 2.0 and DuduOS

We both @Saburo and I tested DuduOS version 251104 and 251101 and the issue is still there, can you please give feedback on the screen resolution and stop investigating the buttons feedback because buttons feedback is fine with other CarLink version

The black border issue is currently under investigation. Regarding the steering wheel track-changing issue, it hasn't been reproduced on either the 7862 or 7870 models. Are you using CAN bus buttons, or buttons programmed via the steering wheel button learning function? If using custom buttons, please specify: - A combination key for track-changing + answering/ending calls, - Or a dedicated track-changing key?

HAccord8

DUDU-Meng thank you for raising that border issue with CarLink 2.0 app.

Well i am using Steering Wheel buttons connected directly to key1 and key2 wires no canbus involved and i programmed through DuduOS settings and the buttons all work with radio and local music but the changing buttons or call buttons that needs to interact with CarLink stops reacting just with CarLink app, this is fixed when device is restarted and breaks again when device goes in sleep and wake up.

Also, the CarLink version 2.25.0926.1708 which is older version does not have such steering wheel control issues at all, even if the device wakes up from sleep the buttons works find and i will continue to use this version as it is good.

So that steering wheel control issue is just with CarLink version 2.25.1020.0906

DUDU-Meng

HAccord8
Alright, I'll conduct further testing on the steering wheel buttons. The resolution issue is still under investigation.

DUDU-Meng

HAccord8
Using the same version for testing, the 1020 can also be controlled normally via the learning-type SWC for playback.
Additionally, I had previously asked whether you had tried both types of song-change buttons.

Here's the video of using SWC on 1020. Please review it and point out any differences you notice on your end. I'll follow up accordingly. Thank you.

DUDU-Meng thank you.

If you could replicate. maybe pass it onto fyt, i think they are the developers of of CarLink 2.0 and also feedback that previous CarLink version 2.25.0926.1708 did not have this issue while newer version CarLink 2.25.1020.0906 have this issue.

HAccord8

DUDU-Meng DUDU-Meng my buttons are set like this

Also, did you try putting device to sleep (not shutdown) then wake it up by giving it ACC(12v) and then try to use the steering wheel control? This is how they break on my end

And one thing more i experienced the same SWC issue when i was using CarLink v2.25.1020.0906 on my TeyesOS before installing DuduOS but i didn't pay much attention to it as mostly i used to put my Unit in shutdown mode so this proves that the issue is with CarLink app and not DuduOS.

And again the older CarLink version 2.25.0926.1708 does not have this SWC issue on my CC3 running DuduOS, so i will continue to use that.

Just one thing, do you have a newer version than version
2.25.1020.0906 of CarLink app?

DUDU-Meng

HAccord8
Below is a video link for your reference. The video shows the Carlink version number.
I will attempt to address the SWC issue after sleep/wake later.

I've identified the cause you mentioned. The new version has changed the communication logic. In the old version, it detected the connection status—as long as a connection existed, SWC would force control over CarPlay. This prevented the device's native music app from playing normally, as CarPlay would immediately take over focus whenever playback started.
Now it detects the music playback status. After connecting to CarPlay, you can still use the device's native music app.
Once connected, you only need to manually start playback or play music on your iPhone to enable SWC control.

HAccord8

DUDU-Meng i think I did try to start music manually from CarPlay or iPhone but SWC still won't take over. i will try again. But the logic you mentioned seems to be true that they changed the communication logic, do you think CarLink should revert back to original logic? Coz that is guaranteed to work.

Also, is there a newer version of CarPlay app released? It is not on App store so it is little harder to keep track of the release, it is usually posted here by yourself or i find on xda.

DUDU-Meng

HAccord8
We've also tested using the same CC3 as you, and everything works fine. Previous versions forced control over CarPlay, so if you wanted to use your device's native music player, you had to disconnect CarPlay. The new version allows both to coexist. You can manually put CarPlay into playback mode. Additionally, try switching to a different music player on your iPhone. We've tested most players here with no issues. Only Kugou Music requires entering the main music interface to function. All other players work perfectly.

HAccord8

DUDU-Meng not the case with mine.

Have a look, i first showed when device was turned on from shutdown (works fine) and then the device was turned on from sleep mode (SWC break)

Also, notice how the resolution does not have black borders when it turned on from sleep mode ( i know you already raised this with developers to investigate) but just wanted to highlight.

DUDU-Meng

HAccord8
The resolution issue is currently under investigation and testing. Regarding the SWC control limitations you previously mentioned, we tested them using CC3 and found no problems.

HAccord8

DUDU-Meng yes no problems I don't have SWC issues with older CarLink version 2.25.0926.1708 and i will continue to use that.

The issue is only with CarLink version 2.25.1020.0906; like i showed in the video. So i will skip this version

Anyway, is there a newer version after Carlink 2.25.1020.0906?
