Hey there,
Just noticed the other day that when I turn the car headlights on the Nav display and screen automatically dims. This is not a problem. The problem I am having is that if you have an iPod video or DVD playing the screen adjusts and becomes really dim as well. I can't seem to find any way to have the screen remain bright at all times with the headlights on. Not going to be a problem when it's completely dark outside...but when its rainy or cloudy out and you need your headlights on it's a bit frustrating. The screen becomes so dark you can't see anything?
