so this morning the navigation in my 04 LS stop working, no display, no radio, no clock.. nothing.. I check the fuse it seem to be fine. anyone have any idea what's wrong?

 

I have a similar problem with my GS430. However, everything works (radio, climate, etc) except for the Navigation... just a blank screen. Were you able to ever figure out your problem? Mines going to the Lexus dealer Monday and I know its gonna cost me an arm and a leg.
