hello all Im new to this forum if Im in the wrong area im sorry, But I'm having a problem with my nav in my 99 GS400. The nav is on but the icon that shows me moving is not moving along the street in the right direction. Its looks like as if it not calibrated correctly or something. has anyone had this problem before. I think it happened when I had my alternater replaced.

 

you can go into the menu and calibrate it. I guess try that and go from there.
