lyle willits

I own a 2006 TL and one day the navigation screen just went blank and the radio station identification that is on a different screen dissapeared. I got to the dvd drive in trunk and noticed there is no light or power. Where is the fuse located for this circuit? Or is there any other possibilities? I did notice there still is a very faint glow to the screen at night so there is power to the lcd screen.
