An information processor includes a setting unit, a course creation unit, a course evaluation unit, and a course setting unit. The setting unit sets a starting point, one or more via-points, and a destination point. The course creation unit creates a course serially coupled between the starting point, the one or more via-points, and the destination point set by the setting unit. The course evaluation unit calculates course evaluation points based on a predetermined evaluation criterion, with respect to the course created by the course creation unit. The course setting unit sets the course as a proposed course for route guidance, on the basis of the course evaluation points.
