System Description

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