US Patent 7406380 Navigation system

A navigation system for providing different modes of navigation guidance to drivers is provided. A smart card stores user information. In a main apparatus, a parameter table storage section stores parameters which are used for controlling the outputting of navigation guidance to an entity. A control section acquires at least one parameter from the parameter table storage section based on the user information stored in the smart card, and thereafter generates information necessary for providing navigation guidance for the entity in accordance with the acquired parameter(s). A display section or an audio output section outputs various information generated by the control section.
