performing a search through the web browser based on the keyword information; displaying a result list based on the search to select a destination for retrieving a path to the selected destination; retrieving a web page of the selected destination through a web browser of a navigation terminal; receiving a user action to receive destination location information on the web page of the selected destination; calling an application program that is one of a plug-in program and a control Application Program Interface to be connected with the web browser, and calling the plug-in program or the control Application Program Interface to transmit the destination location information to the application program; providing the destination location information as destination coordinate information to the navigation terminal by the application program, and requesting a path retrieval with respect to a destination in a coordinate retrieval mode; retrieving a path to the destination based on the destination location information by the navigation terminal; and displaying the retrieved path on a screen, wherein the web page includes a location transmission button and wherein the user action occurs by operating the location transmission button on the web page. ### Claim 2 (depends on 1) The method of claim 1, wherein the keyword information is received through category retrieval. ### Claim 3 (depends on 1) The method of claim 1, wherein the user action pushes the location transmission button in the calling and the transmitting. ### Claim 4 (depends on 1) The method of claim 1, wherein the calling and transmitting transmits the destination location information in a destination address format. ### Claim 5 (depends on 4) The method of claim 4, wherein the providing and the requesting provides the destination address to the navigation terminal, and requests the path retrieval in an address retrieval mode. ### Claim 6 (depends on 1) A non-transitory computer-readable recording medium storing a program for implementing any one of the methods of claim 1. ### Claim 7 A path retrieval apparatus through web browsing, the apparatus comprising: a receiving unit and associated computer hardware to receive keyword information for performing a search through the web browser based on the keyword information and for displaying a result list based on the search to select a destination for retrieving a path to the selected destination; a web retrieval unit and associated computer hardware to retrieve a web page of the selected destination through a communication device of a navigation terminal; an application program storing unit and associated computer hardware to store an application program for receiving destination location information; an application program calling unit and associated computer hardware to call the application program that is one of a plug-in program and a control Application Program Interface to be connected with the web browser when a user action to receive destination location information, is received by the receiving unit, on the web page of the selected destination, and calling a plug-in program or a control Application Program Interface(API) to transmit the destination Program information to the application program; a location information receiving unit and associated computer hardware to receive the location information of the destination web page received by the application program in one of a coordinate information format and a destination address format to the navigation terminal; and a path retrieval unit to retrieve a path based on the location information received from the location information receiving unit, wherein the retrieved path is displayed on a screen; wherein the web page includes a location transmission button and wherein the user action occurs by operating the location transmission button on the webpage. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the keyword is received through category retrieval. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the application program calling unit calls the application program by the location transmission button being pushed by a user. ### Claim 10 (depends on 7) The apparatus of claim 7, wherein the path retrieval unit retrieves the path in a coordinate information retrieval mode or address retrieval mode according to the location information format received in the location information receiving unit.
