PROBLEM TO BE SOLVED: To provide a navigation device and a program capable of recognizing what facilities exist in the designated direction without omission and easily. SOLUTION: The navigation device 100 lists facilities around one's own vehicle based on keywords (categories) inputted, calculates the angle difference in an absolute value between the direction designated by a user (traveling direction or leftward, for example) and the direction of each facility for all the facilities listed, displays them in order of increasing angle difference calculated, and displays only the facility which is in the range the both direction can be regarded approximately as being matched from the angle difference calculated. |
