PROBLEM TO BE SOLVED: To provide a navigation device which can readily confirm the track data of which section is stored to effectively support the drive. SOLUTION: When the instruction of internal storage processing of track data is inputted, a controller 27 sets the present position as a collection end point, provides a place name data for the collecting end point to set it as the name of this point, stores the information in a reference track buffer designated as correcting section information of track data, and transfers the track data stored in a ring buffer to a prescribed area of the reference track buffer followed by storing. The controller 27 displays a list table of the stored reference tracks and urges a user to select a desired track. |
