Garmin Virb light problem

I make even darker pictures from inside my car, mostly in built_up streets.

My lens correct is ON.

That EV lock is only for video en video time lapse.

I have a Mercedes B with a sliding trasparent roof window.

Should I allow more or less light in the car ? Should I lighten the interior of the car ?

With my camera on top of the roof, it is better to open the roof window to receive a better wifi signal.
