When you guys start your car with the headlights on...Is the startup screen dim? Even when I have MAX BRIGHT on when I shut the car off, it starts with a dim picture.

Once the PITA nag screen comes on it is bright again....

 

My car's screen is the same way. Someone in another thread explained that the Navi LCD screen has to basically warm up before brightening to normal.
You will experience the same dimness if you drive for a while after the nag screen shuts off, then boot up the navigation system-- the map will look dim for a few seconds before brightening (I usually drive in familiar areas and don't use the navigation on a daily basis).

 

Same thing happens on mine - i think this is working as intended.

 

Some laptop screens are like that too - they get brighter as the backlight warms up.

 

Mine does the same...

 

I agreed that some time the screen need to warm up and if you have your head light on it will be dim...so why is the screen more brighter when the headlight are shut off?

 

Because it assumes if your headlights are off, it is daytime and the screen needs to be brighter to be visible.

 

I've noticed this too. It seems that it reads that the headlights are on immediately on start, but doesn't get to the "Max Brightness" information until it has booted up completely.

I have also noticed a definite warm-up time for the backlight. Probably a compromise for longevity and extreme temperature conditions that most LCD panels don't have to go through (-20 F in Michigan winters to 130 F in the Arizona sun)

 

Thanks for the input...the reason I don't like this is because if I start my car with the headlights on and put the car in reverse my camera is so dim I can't see the picture. Oh well.

 

Go into the setup and change the dimming setting to manual rather then auto so it will be bright even with the headlights on.
