an output device that outputs at least one of image data, text data, or voice data; and
a control device that causes the output device to output recharging proposal information, the recharging proposal information being information that encourages recharging of a power source that drives a mobile unit,
wherein:
when a first destination and a second destination are set as destinations of the mobile unit, the second destination being a destination for which the mobile unit heads after arrival at the first destination; and
when a cruising distance is shorter than a route distance, the cruising distance being a distance over which the mobile unit is assumed to be capable of continuing to travel with a remaining amount of the power source, the route distance being a distance from a current location of the mobile unit to the second destination,
wherein the control device calculates a difference between the cruising distance and the route distance, and
wherein:
based on the calculation, the control device outputs the recharging proposal information when the difference is less than or equal to a predetermined value;
while the control device does not output the recharging proposal information regardless of existence of a recharging facility between a current location of the mobile unit and the second destination, when the first destination is the recharging facility or the difference is more than the predetermined value, the recharging facility being a facility where the mobile unit is capable of recharging the power source.
