A navigation device comprising: a fuel consumption determination unit that is adapted to determine a fuel consumption in a travel of a vehicle; a fuel consumption information storage unit that is adapted to store point information identifying a departing point and a destination in the travel of the vehicle and fuel consumption information identifying the fuel consumption in a past travel from the departing point to the destination such that the point information and the fuel consumption information are mutually associated; and a display control unit that is adapted to acquire previous fuel consumption information identifying the fuel consumption in a previous travel among the fuel consumption information associated with the point information corresponding to the departing point and the destination in a current travel of the vehicle from the fuel consumption information storage unit, and control a display of the fuel consumption in the previous travel based on the acquired previous fuel consumption information and the fuel consumption in the current travel determined by the fuel consumption determination unit, wherein the display control unit is adapted to acquire a coordinate of a current departing point and a coordinate of a current destination as point information identifying the departing point and the destination in the current travel of the vehicle, said navigation device characterized in that if the display control unit determines that a plurality of sets of coordinates of the departing point and the destination, which are within a predetermined distance from the coordinates of the current departing point and the current destination, respectively, is stored in the fuel consumption information storage unit, the display control unit is adapted to acquire the previous fuel consumption information associated with the set of coordinates having the smallest total value of the distance between the coordinate of the current departing point and the coordinate of the departing point stored in the fuel consumption information storage unit and the distance between the coordinate of the current destination and the coordinate of the destination stored in the fuel consumption information storage unit. a fuel consumption determination unit that is adapted to determine a fuel consumption in a travel of a vehicle; a fuel consumption information storage unit that is adapted to store point information identifying a departing point and a destination in the travel of the vehicle and fuel consumption information identifying the fuel consumption in a past travel from the departing point to the destination such that the point information and the fuel consumption information are mutually associated; and a display control unit that is adapted to acquire previous fuel consumption information identifying the fuel consumption in a previous travel among the fuel consumption information associated with the point information corresponding to the departing point and the destination in a current travel of the vehicle from the fuel consumption information storage unit, and control a display of the fuel consumption in the previous travel based on the acquired previous fuel consumption information and the fuel consumption in the current travel determined by the fuel consumption determination unit, wherein the display control unit is adapted to acquire a coordinate of a current departing point and a coordinate of a current destination as point information identifying the departing point and the destination in the current travel of the vehicle, said navigation device characterized in that if the display control unit determines that a plurality of sets of coordinates of the departing point and the destination, which are within a predetermined distance from the coordinates of the current departing point and the current destination, respectively, is stored in the fuel consumption information storage unit, the display control unit is adapted to acquire the previous fuel consumption information associated with the set of coordinates having the smallest total value of the distance between the coordinate of the current departing point and the coordinate of the departing point stored in the fuel consumption information storage unit and the distance between the coordinate of the current destination and the coordinate of the destination stored in the fuel consumption information storage unit.
