System Description: Notes

The navigation unit, display panel control unit, and the interface dial are the main components of the navigation system. The display panel control unit does not have a touch panel. Instead, an interface dial and surrounding buttons allow control of the navigation system. The navigation unit, and display panel control unit communicate with each other through the GA-Net II communication bus. The navigation unit generates the screen graphics and then passes them to the display panel control unit as Red, Green, and Blue (RGB) color signals, and a composite sync signal.
