2002 LS430 w/ nav. Nav screen no longer changes to dark screen at night.
I've tried everything I can find. I have tried resetting screen colors on
set-up screen, but I can't get any change when changing from light to dark
ambient lighting. Any ideas except Lexus Service??

Thanks,
XPlant

Problem solved, thanks to Club Lexus posts. Apparently when the instrument
panel brightness is set to "Max", the light sensor doesn't put display into
night mode. But turning panel adjust knob back past the click into variable
brightness range, the display now changes from Day mode to Night mode
properly.

Thank you ClubLexus!
