On a Fiat Ducato 2022 series 8 with the 10” infotainment, I have a minor but irritating issue that when the road lights are switched on whilst driving the screen dims and is almost unreadable on a dull day or tunnel etc, when I look in the settings, the box to change this is greyed out but you can change the normal brightness of the screen with lights off? Anybody found a way round this please?
