If the user interfaces (selects) the submenu (step 308), the navigation search block 1084 responds to the memory. Extract address book information and user registration information from block 110 to generate destination candidate list information including a plurality of address (or address, phone number, and digital photographs); In response, the image processing block 114 constructs a destination candidate list screen using the destination candidate list information and outputs the destination candidate list screen to the monitor side (step 310), whereby a plurality of address items (or phone numbers, address addresses, photos, etc.) are displayed on the monitor. The destination candidate list screen including the item) is displayed (step 312).

Then, if the user selects any one of a plurality of address items in the destination candidate list screen as a destination (destination) through the interface (step 314), the destination search block 1084 determines the selected address as the destination and then corresponds to the corresponding path. A search command signal is generated and transmitted to the route search block 1086 together with the corresponding address information (destination address information) (step 316). In this case, when selecting an address (eg, KK gas station near Yongsan station) without detailed information, such as a street address, there may be a plurality of candidate addresses instead of one (for example, 2-3). The interface allows you to select only one candidate address as the destination.

In response, the route search block 1086 transmits the voice guidance information of the corresponding address determined as the destination to the voice processing block 116, so that the address address selected by the user in the address book and the user registration information through the speaker not shown is the destination. A guidance service is provided for voice guidance that the information has been selected (step 318).

At the same time, the route search block 1086 extracts map information up to the corresponding address through search of the map DB 112 based on the corresponding address information (destination information) to form map information data, and then processes the image information block 114. ), A navigation mode is executed in which a map information screen for a driving route in which a user selects one of the address book in the pre-stored address book and the user registration information as a destination through the menu interface method is displayed on the monitor (step 320). ).

Meanwhile, according to the present invention, a user can select a phone number as a destination on a destination candidate list screen including an address, a phone number, a digital photograph, and the like. In this case, the destination search block 1084 selects the phone number DB 202. The process of searching for and retrieving the address information of the selected telephone number and recognizing it as a destination may be performed to transfer to the route search block 1086.

Unlike the above, if the address information corresponding to the telephone number selected by the user is not present in the telephone number DB 202, the destination search block 1084 generates an address information request message to generate an external server 204 together with the selected telephone number. The user may request address information on the telephone number selected by the user through the process of transmitting the information to the user, and then may recognize the address information transmitted from the external server 204 as a destination and transmit the address information to the route search block 1086. .

4 is a flowchart illustrating a main process of selecting a destination for guiding a route in vehicle navigation according to an embodiment of the present invention.

Referring to FIG. 4, while the navigation device is in the standby mode (step 402), if the navigation user executes an interface for destination search (step 404), the destination search block 1084 displays characters from the memory block 110. The search menu screen data including the search menu is extracted and transferred to the image processing block 114, and as a result, a search menu screen including the text search menu is displayed on the monitor (step 406).

Accordingly, the navigation user can input a character to select as a destination through the selection of the character search menu (step 408). When the user inputs a desired character (step 410), the destination search block 1084 displays a memory block ( 110 to search for address information (address book information and / or user registration information) including input characters (step 412), and generate destination candidate list information including at least one address address extracted through such a search. This is then passed to the image processing block 114. As a result, the image processing block 114 constructs the destination candidate list screen using the destination candidate list information and outputs it to the monitor side (step 414), whereby a destination candidate list screen including at least one address item is displayed on the monitor. (Step 416).

Then, if the user selects any one of a plurality of address items in the destination candidate list screen as a destination (destination) through the interface (step 418), the destination search block 1084 determines the selected address as the destination and then corresponds to the corresponding path. A search command signal is generated and transmitted to the route search block 1086 together with the corresponding address information (destination address information) (step 420).

In response, the route search block 1086 transmits the voice guidance information of the corresponding address determined as the destination to the voice processing block 116, so that the address address selected by the user in the address book and the user registration information through the speaker not shown is the destination. A guide service is provided to guide voice that it has been selected (step 422).

At the same time, the route search block 1086 extracts map information up to the corresponding address through search of the map DB 112 based on the corresponding address information (destination information) to form map information data, and then processes the image information block 114. ), A navigation mode is executed in which a map information screen for a driving route in which a user selects one of address addresses in a pre-stored address book and user registration information as a destination through a text input method is displayed on the monitor (step 424). ).
