Abstract
A navigation device includes a navigation information storage unit in which navigation information, including the user-provided data, is stored; and a human machine interface unit that outputs the user-provided data and navigation information other than the user-provided data separately on an output device, that displays a warning message, read from the navigation information storage unit, and a screen prompting for an input for selecting whether to perform navigation processing based on the user-provided data when an instruction for performing navigation processing based on the user-provided data is input from an input device, and that causes a control unit, which performs navigation processing, to perform navigation processing based on the user-provided data when an instruction for performing navigation processing based on the user-provided data is input from the input device. In this way, a navigation system where user-provided data and official data are reliably combined can be provided.
