    • PROBLEM TO BE SOLVED: To prohibit input operation of a navigation system during vehicle traveling. SOLUTION: An ECU 14 for navigation operates the present position from radio waves from a plurality of artificial satellites, and displays a map of a measuring position and its periphery on a liquid crystal display 18. A camera 22 for a driver is provided on a position for imaging a driver's 38 face from the front. An ECU 36 for detecting the face direction detects the face direction based on an image signal from the camera 22 for the driver, and outputs face-direction detection data corresponding to the face direction (angle in the right/left direction) to the ECU 14 for navigation. The ECU 14 for navigation has an input prohibition means 60 for prohibiting input operation during vehicle traveling, a face-direction determination means 62 for determining whether the driver's 38 face is faced to the vehicle front or not by the face-direction detection data supplied from the ECU 36 for detecting the face direction, and an input permission means 64 for removing input prohibition and permitting the input operation when the driver's 38 face is faced to the vehicle front.
