Here, reference numeral 832 includes information on a security post location and an icon or avatar representing a security post corresponding to the security post location information, and the at least one additional information 821-1 and 821-2 in the road guidance information. , 831, and 832, one of a specific icon, a specific avatar, and a specific pattern corresponding to the additional information 821-1, 821-2, 831, and 832 is displayed on the display unit 406, respectively ( 842, 843, 844, and 832 (S540).

In operation S530, as a result of checking whether there is additional information adjacent to the current location of the navigation device 400 among the at least one additional information, additional information adjacent to the current location of the navigation device 400 is determined. If there is no (or if there is no additional information adjacent to the current position and / or the direction of travel of the navigation device 400), the road guidance information is generated using the at least one additional information, the generated road guidance Information is output to the display unit 406 and / or the audio output unit 407. For example, as illustrated in FIG. 13, road guidance information for the at least one additional information 821-1, 821-2, 831, and 832 is generated and output. That is, for the at least one additional information 821-1, 821-2, 831, and 832, screen information (eg, area display 821-1, 821-2-2, which indicates an area corresponding to the additional information) is displayed. 831) or road guide information including an icon (or information, such as an avatar) 832 corresponding to additional information, to generate the road guide information, and display the generated road guide information on the display unit 406 and the voice output unit 407. )

In this case, the screen information (region information or POI information) corresponding to the additional information displayed on the display unit 406 includes any one of a predetermined icon, a specific avatar, and a specific pattern preset according to the characteristics of each additional information. It may be (S550).

In addition, if the at least one additional information is not included in the matched map information (confirmation result in step S520), the guidance information is generated based on the matched map information, and the generated The road guide information is output to the display unit 406 and / or the voice output unit 407 (S560).
