feature. The upper dash display (Radio-computer), the lower dash (HVAC), and the dash display behind the steering all have there own photocells. During the day, I cannot see the upper dash display with the sun roof opened, because there is usually a shadow across the photocell (the little "light" next to the DSP button). I would much prefer the dash to be at its brightest during the day, even on overcast days. The dimmers should only work when the lights are on, not all the time. Why did they spend the money to make it so I couldn't see the dash display? I can always see the display behind the steering wheel -- it is always bright. You'd thing that would be the one that should be dimming during the day if anything.
