If the moving body 2 approaches the first destination by the first predetermined distance during route guidance (S1: Yes), the proposal unit 18 advances the supplement proposal process to step S2. If the route guidance is not being performed, or if the moving body 2 is not in a state of approaching the first destination by the first predetermined distance (S1: No), the proposal unit 18 proceeds to step S5.
- the proposal unit 18 determines whether the first destination is a replenishable facility or home. If the first destination is a replenishable facility or home (S2: Yes), the proposal unit 18 proceeds to step S5. If the first destination is not the replenishable facility or the home (S2: No), the proposal unit 18 proceeds to step S3.
- step S3 the proposal unit 18 determines whether or not the second destination is set. If the second destination is set (S3: Yes), the proposal unit 18 proceeds to step S5. If the second destination is not set (S3: No), the proposal unit 18 proceeds to step S4.
- step S4 the proposal unit 18 determines whether or not the distance from the starting point or home of the moving body 2 to the first destination is greater than or equal to the second predetermined distance. If the distance is greater than or equal to the second predetermined distance (S4: Yes), the proposing unit 18 proceeds to step S5. If the distance is less than the second predetermined distance (S4: No), the proposal unit 18 ends the replenishment proposal process without outputting replenishment proposal information.
- step S5 the proposal unit 18 determines whether the remaining amount of the power source is equal to or less than a predetermined percentage. If the remaining amount of the power source is equal to or less than the predetermined ratio (S5: Yes), the proposing unit 18 proceeds to step S9. If the remaining amount of the power source exceeds the predetermined ratio (S5: No), the proposal unit 18 proceeds to step S6.

If the cruising distance is insufficient (S6: Yes), the proposing unit 18 proceeds to step S9. If the cruising distance is sufficient (S6: No), the proposing unit 18 proceeds to step S7.
- step S7 the proposal unit 18 determines whether or not the number of replenishable facilities along the route to the second destination or departure point is less than a predetermined number. If the number of replenishable facilities is less than the predetermined number (S7: Yes), the proposal unit 18 proceeds to step S9. If the number of replenishable facilities is equal to or greater than the predetermined number (S7: No), the proposal unit 18 proceeds to step S8.
- step S8 the proposal unit 18 determines whether or not stormy weather is forecast around the current location of the moving body 2 and along the route from the current location to the second destination within a predetermined time from the current time. If there is a forecast of stormy weather (S8: Yes), the proposal unit 18 proceeds to step S9. If no forecast of stormy weather is given (S8: No), the proposal unit 18 ends the replenishment proposal process without outputting replenishment proposal information.
- step S9 the output control unit 19 outputs the replenishment proposal information 38 to the output device 12, and proceeds to step S10.
- step S10 the proposal unit 18 determines whether or not there is an instruction from the user to search for replenishable facilities. If there is an instruction (S10: Yes), the navigation unit 17 searches for replenishable facilities in step S11, and ends the replenishment proposal process. If there is no search instruction for replenishable facilities (S10: No), the navigation unit 17 ends the replenishment proposal process without outputting replenishment proposal information.
