PROBLEM TO BE SOLVED: To provide a navigation system excellent in operability capable of reading and transferring map data to a hard disc followed by storing in the eject operation of a recording medium, and reproducing a desired recording medium during navigation. SOLUTION: The CPU 11 of this navigation system discriminates its own vehicle position based on the sensor output of a sensor part 16 and the position measurement output of a GPS receiving part 17 to perform a navigation operation. When an eject button 19a or the like of an operation part 19 is depressed, a map data in a prescribed range delimited according to its own vehicle position of map data recorded in a DVD-ROM 1 is transferred to and stored in a map data storage area 15a of a hard disc 15 through a RAM 13. In the display processing to a display 20, the map data is transferred from the hard disc 15 to a display control part 21 to execute display processing. |
