1. A navigation device, comprising:
a processor configured to:
select a first running route up to a destination of a vehicle by a predetermined algorithm unrelated to noncontact power supply;
calculate, assuming that the vehicle runs on the first running route, a value of a parameter relating to a projected supplied electric energy supplied at a power supply section where power is supplied by noncontact from a ground power supply apparatus on the first running route to the vehicle, wherein
the value of the parameter relating to the projected supplied electric energy is calculated based on an average speed of vehicles running over the power supply section in the past, a length of the power supply section, and the supplied power per unit time from the ground power supply apparatus to the vehicle when the vehicle runs over that power supply section; and
in response to the calculated value of the parameter being less than a predetermined standard electric energy,
select a second running route by which the projected supplied electric energy will be greater than or equal to the predetermined standard electric energy;
propose, as a running route up to the destination, the first running route and the second running route;
make a user select a running route for road guidance among the first running route and the second running route; and
set the running route selected by the user as the running route up to the destination.
