The present invention relates to an apparatus and a method for providing location based information using a smartphone. The location based information providing apparatus using a smartphone is characterized by providing location based information in real time by linking AVN in which a telematics function is not embedded to a smartphone. According to the present invention, location based information can be provided in real time by linking AVN in which a telematics function is not embedded to a smartphone, thereby improving user convenience and user satisfaction for an AVN product. In other words, user convenience can be improved by displaying real time information such as travel information (cultural events), real estate information, price information (gas stations, restaurants, etc.) through AVN. Moreover, because internet access can be obtained through a smartphone, AVN does not need to realize a separate internet access function.[Reference numerals] (AA) ' Bluetooth communication' or ' Wi-Fi Direct Communication' ; (BB) Mobile communication data communication network; (CC) Mobile communication company; (DD) InternetCOPYRIGHT KIPO 2014
