Disclosed is a method for providing a navigation service by a mobile terminal. According to the present specification, when there is at least one mode change section in which a navigation mode needs to be changed in a discovered path, map data, which serves as a basis for path guidance, is changed from first map data to second map data when entering the mode change section, and thus the navigation service can be successively provided in the changed navigation mode. Accordingly, by inputting a destination once, it is possible to implement a seamless path guidance service using a mobile even in an environment in which a vehicle cannot enter.
