Your IS 300h Exec has Lexus navigation (rotary controller in the centre console)
Make sure you're on the Nav screen is showing the map, press down on the rotary controller to get the control icon on the screen - tilt the rotary controller so it moves on the screen to the compass picture in the top left hand corner and then press the centre controller to change the layout... North facing, Direction of travel or 3D view.
Hope that helps?
