A route setting device includes a current location detecting section, a transit point setting section, a recommended route calculating section and a transit point determining section. The transit point determining section is configured to determine whether the user selected transit point is a disposable type of transit point and whether the transit point set is a substitutable type of transit point based on the user setting instruction. The recommended route calculating section is configured to calculate a non transit point recommended route without requiring the user selected transit point to be along the non transit point recommended route when the user selected transit point is the disposable type, and an alternative transit point recommended route with the alternative transit point located along the alternative transit point recommended route when the user selected transit point is the substitutable type.
