摘要： A car navigation system capable of performing both real-time route guidance for a driver, and non-route-guidance display and operation of car navigation functions such as destination setting and vicinity searching for a non-driver, without necessitating a high-speed CPU or a high-performance drawing processing section. A display apparatus 200 is equipped with a CPU 210, an operating section 220, and drawing processing sections 230 and 240 corresponding to two display screens 250A and 250B, navigation-related processing is performed in a navigation apparatus 100, and drawing processing for the driver and drawing processing for a non-driver are executed independently by drawing processing sections 230 and 240 respectively of display apparatus 200. Functions are shared between navigation apparatus 100 and display apparatus 200.
