Abstract

When a secret mode is set, a variety of information including driving log containing destination, routes, distance covered, and direction of travel are stored in second storing means. Thus, when a user wants to keep various information unique to the user secret strictly from other users at the time the navigation device is used, the user has only to set a memory mode to a secret mode to use the device. After that, the user has only to remove the second storing means from the main body of the device to hold and manage the storing means by himself or herself.
