Hello,
I’m using a DUDU7 head unit installed in my Geely Emgrand. I’m currently on firmware version 3.6 and using the stock launcher.
I have an issue with the automatic day/night mode switching feature.
In the system settings, I have enabled automatic switching of the theme and screen brightness based on the vehicle's lights (via CAN signal). However, this feature does not work — the tablet does not respond when I turn on the parking or head lights.
Manual switching of day/night mode works correctly, and the schedule-based mode also functions as expected. The CAN bus signal is confirmed to be present and correctly received by the unit, but it does not trigger the theme switch.
I have checked the settings and couldn’t find the "Lamp/Time" toggle under Display settings, which was suggested in some older threads. I suspect this option may have been removed in firmware 3.6.
Could you please confirm if this is a known issue in version 3.6? Is there any workaround or upcoming fix planned for restoring automatic day/night theme switching via CAN input?
Thank you in advance.
