Abstract
A display device is disposed in a car and a display screen is switched based upon coordinate data showing the touched position which is output from a touch tracer which is disposed where it can be accessed by a driver, and "on" data that shows that the touch tracer has been press-operated. The display device displays small button display portions to select a next display operation which is to be displayed on the map screen. The button display portions which are shown on the map screen in an input state of the coordinate data from the touch tracer are displayed in an expanded state. By so doing, the driver can easily confirm the display content of the button display portions so that it is possible to improve the operability of the touch tracer for the selection of the button display portions.
