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.
Headlight Sync Issue After Updating to 3.6 Beta – Night Theme Not Working
Please check Setup - Display Settings - Day/Night Switching Mode - if it is Light Control Mode or Light Mix Mode.
DUDU-Meng The day theme is set to the default white theme, and the night theme is set to a dark theme.
However, both Headlight Switch Mode and Lighting Mix Mode do not work when the vehicle’s headlights are turned on.
The Lighting Mix Mode is set to 18:00 (6:00 PM), and it only activates according to the time setting — not the headlight status.
