The type of the mobile phone is recognized by the phone type recognition unit, and the type of the mobile phone is determined according to the recognized mobile phone. Since the function is set by the control unit, it has an effect that a function corresponding to the connected portable telephone can be automatically selected.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In these drawings, the same members are denoted by the same reference numerals, and duplicate description is omitted.

FIG. 1 is a block diagram showing a navigation device according to an embodiment of the present invention, FIG. 2 is an explanatory diagram showing the device configuration of the navigation device of FIG. 1, and FIG. 3 is connected in the navigation device of FIG. It is an explanatory view showing a selection function of a mobile phone.

As shown in FIG. 1, the navigation apparatus according to the present embodiment is mounted on a main body or separately as an external remote controller, and has an operation input unit 1 for performing each operation by a user and an operation control of the entire apparatus. A central processing unit (control unit) 2 for performing the operation, a map recording medium 3 such as a CD-ROM or DVD storing map information, and position information received by the antenna 5 are compared with the map information of the map recording medium 3. GPS section (position detecting section) 4 for detecting the current position
And a ROM section 6 storing a menu screen, a main body operation program, various settings, screen display characters, and the like in which communication-related operation commands are summarized, and a list of telephone numbers of communication partners input from the operation key section 1. And a RAM unit 7 in which data such as user settings, various user settings, and external input information are stored in an erasable manner, and image data obtained by superimposing the current position detected by the GPS unit 4 on the map information of the map recording medium 3. A display device 8 to be displayed; a mobile phone 9 such as a PHS or a digital mobile phone connected to the device main body 11 for transmitting and receiving information such as position information, character information, images, and voice; and the type of the mobile phone connected (For example, P
Communication I / F to detect HS or digital mobile phone)
(Interface) unit (telephone type recognition unit) 10.

As shown in FIG. 2, data communication is performed between the portable telephone 9 and the apparatus main body 11 via a connector 12 for connecting the portable telephone 9 to the apparatus main body 11. Is determined, the central processing unit 2
, A predetermined function recorded in the ROM section 6 such as a command or operation restriction at the time of PHS connection, a priority of judgment, or a command, operation restriction at the time of connection with a digital mobile phone, or a priority of judgment is automatically selected. Is done.

The central processing unit 2 of the navigation device has a built-in communication modem function, and also functions as a communication modem for data communication.

Next, the operation of the navigation device having such a configuration will be described.

First, when the portable telephone 9 is connected to the apparatus main body 11, the type of the portable telephone 9 is determined by the communication I / F unit 10.

When it is determined, for example, that the PHS is connected, a predetermined function is automatically selected, and the mode is automatically switched to the menu configuration, setting, and operation restriction when the PHS is connected (see FIG. 3). That is, the PHS location information search function operates, the communication speed is set to 32000 bps, the P-mail function operates, and data transmission from another PHS can be accepted. Then, an incoming call from a digital mobile phone that cannot completely achieve communication data compatibility is rejected.

Further, for example, when it is determined that the digital mobile phone is connected, a predetermined function is automatically selected, and the menu structure, setting, and the like when the digital mobile phone is connected are connected.
The operation is automatically switched to the operation restriction (see FIG. 3). That is,
The PHS location information search function displays an error, the communication speed is set to 9600 bps, the P-mail function displays an error, and data transmission from another digital mobile phone can be accepted. Then, the incoming call from the PHS is rejected.

When it is recognized that a terminal other than the PHS or the digital mobile phone has been connected, an error message is displayed and confirmation of the terminal is prompted.

As described above, the type of the portable telephone is determined, the target operation such as data communication is completed, and when the user disconnects the portable telephone from the cable, the setting is continued until a new terminal is connected. State is maintained.

As described above, according to the navigation device of the present embodiment, the type of the portable telephone connected by the communication I / F unit 10 is recognized, and the function corresponding to the recognized portable telephone is centrally operated. Since the setting is made by the arithmetic unit 2, it becomes possible to automatically select a function according to the connected portable telephone.

[0021]

As described above, according to the present invention, the type of the portable telephone is recognized by the telephone type recognizing section, and the function corresponding to the recognized portable telephone is set by the control section. Therefore, an effective effect is obtained that a function according to the connected portable telephone can be automatically selected.

As a result, not only the operation is simplified, but also an effective effect is obtained that an efficient communication speed is automatically selected and communication charges can be saved.
