2018 OB Ltd. Struggling with the Nav display brightness. I set it to Auto brightness and it's fine in the daytime. And at night, there is a degree of dimming, but it's still really bright. I have to go Manual and turn it down to 1 to get it comfortable on the eyes in a dark car. I know I can turn it down on the panel lights rheostat, but that also dims my backlighting, which I don't want to do. For night settings, is there any way to keep the panel lights up and get the Nav light less bright without going to Manual mode?
