Okay so here's my problem. I have a 2008 IS 250 and my navigation doesn't start up at all the screen doesn't start up at all. No logo or anything but every once and awhile while driving the navigation will boot up and work for 3 to 5 minutes before freezing and the screen slowly whites out and stays that way until I turn the car off. Another odd thing that kinda happened was once the screen booted up the lay out for the ac changed while other times its the orginal lay out. The radio still works and if i can turn on the ac before the navigation frezzes it stays on where i left it. I've tried reseting the car by disconnecting the battery, as well as checking my fuse box. Does anyone know what's going on?
