Abstract
In a navigation device, when a hardware switch is turned “ON” so that Valet mode is “ON,” use of destination designating methods using a memory point and a position of home is prohibited. When the hardware switch is turned “OFF,” a user authentication of a password input is required. When the user authentication is successfully executed, the use of the destination designating methods using the memory point and the point of home become operative. This enables an authorized user to use the destination designating methods using the memory point and the point of home, methods which relate to personal information. By contrast, this prevents an authorized person who does not know the password from accessing the personal information since the authentication is not provided. The leak of the personal information that is registered in the navigation device can be thereby restrained.
