Abstract: A navigation device and a route guiding method. The route guiding method includes: displaying a current map including a position indicator; displaying a related map that corresponds to the current map; and displaying the current map after a set period of time has elapsed. The set time period can be set by a user. Therefore, the travel simulation of the route from the current position to the a location desired by a user may be displayed, or the route may be zoomed in or out to be displayed, based on settings input by a user, and thus the user can travel safely.

Abstract: A method and apparatus are provided for automatically updating data broadcasting through a broadcasting terminal, while audio/video (A/V) broadcasting is being watched. The method includes: comparing a predetermined update period of the data broadcasting with an elapsed time; if the elapsed time is greater than the update period, and if a main/sub channel of A/V broadcasting currently being watched by a user is different from a predetermined channel, changing the main/sub channel of A/V broadcasting into the predetermined main/sub channel; processing the predetermined data broadcasting signal; and providing the data broadcasting signal to a user. The method and apparatus can be used without additional key input by a user, reducing, traffic accidents caused by distraction of the user in the process of key input for watching digital broadcasting.
