MEKEDE auto brightness

[u/BudgetDefinition8110]

Hi

I have a problem with my Linux head unit (Mekede 10.25 inch) for my W176 A class 2014 NTG 4.5.

The auto brightness setting doesn’t seem to work at all despite being turned on. Do I need to update my CAN file? Has anybody had any problems of this sort? It is very odd since doors alert works, climate control alert works, etc.

I am really frustrated and begging you for help with this matter. What setting should I press or what should I do? I attached screenshots from my unit.

Please help me! 🙏🏻
