There are 3 settings on the dimmer switch:
-- Have both the dash and NAV dim when lights are turned on
-- Have just the dash but not the NAV dim when the lights are turned on (hold down + button until it reaches full brightness and then press - once)
-- Have both the dash and NAV stay at full brightness (hold down + button)
I've also noticed on mine that when there is still some light outside (such as at dusk) and I turn my lights on the NAV doesn't dim right away until it gets darker. I can't be sure but I suspect there is a light sensor on the NAV unit that auto dims when the ambient light reaches a certain threshold. I suspect this is because the night mode is difficult to see (with the black background) unless it's totally dark so the unit tries to compensate by going to night mode when it's dark enough. I still think it doesn't wait long enough and at times I've had to manually turn up the brightness to see and then turn it down when it gets darker but it's better than nothing.
