PURPOSE: To easily input a destination even during driving by displaying received information on a display, selecting the destination out of destinations in the data by an operation part and inputting it by keys as it is.

CONSTITUTION: A vehicle is equipped with a beacon antenna 1, receiver 2, microcomputer 5, display 7 and operation part 8 and when entering the communication area of an on-road antenna, a receiving operation is started. Data are successively transmitted, and out of the data, the microcomputer 5 selects crossings, branching point information and the destination or the like. A storage device 6 previously stores the crossings and the shapes of branching points, and drawing coordinates on a screen are calculated and displayed on the display 7. When there is the key input of the operation part 8 during the display, a cursor 9 is moved. The destination is inputted by pushing a decision key while selecting the destination by the cursor 9. Thus, a driver can safely input the destination even during driving.
