Data transmission from the communication center 3 to the subunit 2 and data transmission from the subunit 2 to the car navigation device 1 can be repeated until voice communication is completed.

  At this time, if communication between the operator and the user is insufficient, the operator may transmit data different from the data intended by the user. However, by repeatedly performing data communication during voice communication, the user can immediately confirm the contents of the data, so that the operator can be requested to send another data. When the voice communication is finished (step S13), all the processes are finished.

  If it is necessary to store the data in the subunit 2, the data can be transmitted again from the BT communication unit 12 of the car navigation device 1. When data is received by the BT communication unit 22 of the subunit 2, the data is stored in the storage unit 23 via the control unit 20.

When communication with the communication center 3 is established, data communication with the communication center 3 becomes possible via the DCM communication unit 11. At this time, the connection request U1 includes an identifier of the subunit. Specifically, the identifier is a telephone number of a mobile phone that is a subunit.

  Thereafter, it is checked whether or not the subunit is registered (step V4). If the subunit 2 is not registered in the HDD 16, or if it cannot be connected via the BT communication unit 12 even though it is registered, only voice communication via the DCM communication unit 11 is performed (step V5). .

  It is determined whether the voice communication is finished (step V6). When the voice communication is finished, the data stored in the storage device 33 of the communication center 3 is transmitted via the DCM communication device 31 according to the instruction of the control device 30.

The operator in the communication center 3 receives the user's order by a call with the user of the car navigation device 1. The operator transmits the data ordered by the user via the DCM communication device 31.

  The DCM communication unit 11 of the car navigation apparatus 1 to which the communication apparatus of the present invention is applied receives data from the communication center 3 and stores it in the HDD 16. When the connection with the subunit 2 cannot be established, the process is completed.

  If the subunit 2 is registered in the HDD 16 of the car navigation device 1 to which the communication device of the present invention is applied and can be connected to the subunit 2 (step V8), voice communication is started (step V9). The display unit 14 is a two-screen display (step V10).

Receiving this, the communication center 3 transmits a connection completion notification UX4 to the subunit 2 using the telephone communication device 32. In this way, communication between the subunit 2 and the communication center 3 is established.

  The connection request U1 and the connection request UX3 transmitted to the communication center 3 include an identifier such as a telephone number of a mobile phone that is a subunit. The communication center 3 recognizes that these two identifiers are communication by the same car navigation apparatus 1 by these identifiers.

  Furthermore, the current location information acquired by the GPS unit 15 can be included in these connection requests. By notifying the operator of the communication center 3 of the current location information, it becomes easy to specify data requested by the user.

The control unit 10 of the car navigation device 1 transmits a reception completion notification U8 to the communication center 3 via the DCM communication unit 11. If the reception completion notification U8 is not received within a predetermined time after the transmission of the data U7, the communication center 3 retransmits the data U7. Data transmission from the communication center 3 to the car navigation device 1 can be repeated until the voice communication is completed.

  At this time, if communication between the operator and the user is insufficient, the operator may transmit data different from the data intended by the user. However, by repeatedly performing data communication during voice communication, the user can immediately confirm the contents of the data, so that the operator can be requested to send another data. When the voice communication ends (step V13), all processing ends.
