fog light

[gtbigup01]

Hey guys I recently purchased a 06 Denali and noticed that everytime i turn on my fog lights the nav screen would dim. Is this normal in Yukons, Tahoe?

Is the nav an aftermarket unit?

Its because it is set to auto dim when the headlights come on. Look at the settings you can change the settings.

Yep, its stock....

Whenever you override the auto settings for your headlights and turn them or the fog lights on manually, it thinks its night time...so it dims the NAV and dash lights...so it wont be so distractingly bright while driving at night
