Hello,
I have a GS 400 1999.. This morning when I got into my car and start up the engine,
Navigation has no power…blank screen. The stereo is the only thing that work. No Climate control or the stereo amp….Every thing work that is not part of the Navigation.

Is there a fuse for the Navigation? IF yes, where is it located at?
How do I reset the power?

Or time to get a new Nav.

Thanks

 

Maybe you should try to unplug the nav ecu and plug back in that is in the trunk area.

 

unplug the negative wire of your battery for 15 minutes to reset the ecu let me know wat happen
