Abstract
A navigation system executes a portable mode for guiding a person when a GPS antenna is connected with it and a speed signal has not been inputted for ten seconds or more. The portable mode enables a predetermined function being nonfunctional in an in-vehicle mode for guiding a vehicle while it disables a predetermined function being functional in the in-vehicle mode. It furthermore modifies, for the portable mode, a predetermined function set in the in-vehicle mode. The navigation system can thereby utilize functions suitable for guiding a person-guiding instead of guiding a vehicle, which effect enhances usability of the system.
