For example, the second map matching unit 603 generates an estimated position based on the first position data and / or the second position data, and generates the estimated position and the second storage unit 604. Links in the map data stored in the subframe are matched according to the link order, and the matched map information (map matching result) is output to the second controller 607. In this case, the matched map information (map matching result) is information generated by referring to road conditions using preset user information, TPEG information, current vehicle state information (including oil state, tire pressure state, etc.), and the like. .

Thereafter, the second controller 607 generates road guide information based on the matched map information, and transmits the generated road guide information to the portable terminal 500. In addition, the generated road guide information may include one or more pieces of information among map data, POI information, lane information, driving speed limit information, and turn-by-turn list information.

In addition, the second control unit 607 transmits various types of information used for path search or road guidance information generation, such as map data and POI information, which are pre-stored in the second storage unit 604, to the portable terminal 500. (S410).

Thereafter, the first controller 506 outputs the received road guide information to the first display unit 504 and / or the first audio output unit 505. Here, the first display unit 504 and the first audio output unit 505 may be configured as one device, for example, an output unit (not shown).

In addition, the first controller 506 controls the first map matching unit 502 to pre-store the received estimated location and map data (the received map data or the first storage unit 503). Maps (links) included in the map data) and generate road guide information based on the matched result, and output the generated road guide information to the first display unit 504 and / or the first voice output. It may output to the unit 505.

The first controller 506 may generate road guidance information based on the received matching result (or the matching result of the received estimated location and the link included in the map data), thereby generating the generated road guidance. Information may be output to the first display unit 504 and / or the first audio output unit 505 (S420).

Thereafter, the second control unit 607 is transferred through the first communication unit 507 in a state where communication between the first communication unit 507 and the second communication unit 608 including the respective hands-free modules is connected. The multimedia data is reproduced or the multimedia data (including various broadcast signals) received through the antenna (not shown) of the navigation device 600 is reproduced.

In addition, when a storage function is selected by a user through an input unit (not shown) included in the navigation device 600 during the reproduction of the multimedia data, the second control unit 607 may read the multimedia data being played. 2 is stored in the storage unit 604 (S430).

As described above, in the navigation device 600 for reproducing multimedia data, convenience of use may be provided by simultaneously storing multimedia data being reproduced without a separate processing process.
