PROBLEM TO BE SOLVED: To quickly display logo marks of surrounding facilities even when the center position of a displayed map moves by a scroll operation or the like while the map is displayed. SOLUTION: A storage means stores map data and logo mark data for showing logo marks of facilities. The logo mark data includes: a data storage section wherein identification numbers and position coordinates of each logo mark are classified for each genre and stored; and a table wherein storage position information showing the storage position of the logo marks belonging to each genre in the data storage section is stored. A logo mark display means refers to the table, specifies the position of logo mark data belonging to the genre selected by a user in the data storage section, acquires the logo mark data, and displays the logo mark.
