Abstract
When an instruction to start a setting operation for a destination is provided by a user during a period in which a navigation server is not available for a mobile device while a navigation function, which uses the navigation server providing distribution function of map data and route search function, of the mobile device is being utilized in a navigation device, the navigation function provided in the navigation device itself is activated and is caused to perform destination setting operation.
