Hello,
I have installed the DUDU7 13.3-inch head unit in my vehicle. When I first installed it, the firmware version was 241222. At that time, when I turned on the vehicle's headlights, the system would automatically switch to the night theme and the device screen dimmed appropriately for nighttime driving.
However, after updating to 3.6 Beta4, the synchronization with the vehicle's headlights no longer works. The screen no longer dims, and the night mode is not activated automatically.
I have now updated to 3.6 Beta5, but the issue still persists — the headlight sync and night mode functions are not working at all.
Please note: When I updated to version 3.6, I did not include the factory reset file during the update process.
