Abstract
A navigation method and system for guiding a user to a destination while providing area-specific information useful for guiding and warning the user such as local traffic laws, driving conditions, traffic customs, weather conditions, etc. that is specifically tailored for each user. The area-specific information is customized for a user in order to give the area-specific information to the user that is most relevant to that particular user. The navigation system informs the user of the area-specific information that is different from that of the user's home area or the information specific to the calculated route to the destination or unique to the current location of the user. Further, the navigation system customizes the calculated route such that driving conditions and situations that are unfamiliar to the user will be minimized.
