Car battery was dead this afternoon. Replaced it and when I started the car up the navigation screen was black. No audio controls, No climate control. Anything that has to do with the touch screen monitor or buttons around the unit (including the clock) are black and not working.....

Everything else seems to be fine....

HELP....

thanks

Fuse perhaps?

If not fuse, try hitting the voice command.button.on.steering wheel and saying "screen on" as maybe it's off.

I know mine one time just randomly went off. All of the functions like the radio and AC were working, but the screen was completely black. Scared the hell out of me because I thought I was going to need a new monitor, but the next time I started it up, everything was back to normal. It was like it just needed to be rebooted.

thanks for your suggestions.

It was a fuse...... dealer was nice enough to replace no charge......
