DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for specifying the position of a vehicle by a GPS satellite receiver, a self-contained navigation device, and the like, and performing route guidance to a destination, and a portable device in which a user stores individual specific information. The present invention relates to sharing of user information and devices with an information terminal device.

[0002]

2. Description of the Related Art In general, an on-vehicle navigation device detects a current position of a vehicle, reads map data in the vicinity thereof from a recording medium, and displays a map image around the vehicle on a screen. In the center of the screen, a vehicle position mark indicating the position of the vehicle is displayed, and a map image in the vicinity is scrolled according to the progress of the vehicle around the vehicle position mark, so that the map information around the position of the vehicle is always known. It has become. Further, a driver or the like can change the display scale of the map image and perform a scroll operation of the map image by operating a remote control (hereinafter, referred to as “remote control”) unit.

On the other hand, portable information terminals, which are portable information devices, have become widespread due to miniaturization of memory and CPU and power saving. These portable information terminal devices are:
Various types of information (address book, telephone number, schedule, etc.) individually registered by the user are stored, and the selected information can be displayed on the display unit based on the operation of the user. Recently, a large number of devices employing a color liquid crystal for the display section have become widespread.

[0004] Each of the portable information terminal device and the navigation device can be said to be an information device, and has a schedule, an address book,
It has a function of storing a telephone number and the like, and displaying necessary information on a display unit owned by each device by a user operation.

[0005]

As described above, with the widespread use of car navigation systems and portable information terminal devices, users are increasingly having these devices. However, information sharing between these information devices has not been attempted very much, and input of information to each device is often performed by individual input by a user, and procedures such as data update become very complicated. In addition, problems such as improper data sharing due to user input mistakes have arisen.

[0006] In addition, since recent navigation devices have become multifunctional, an operation screen for performing a predetermined navigation operation often has a complicated hierarchical structure. Therefore, when operating the navigation device,
The key has to be pressed many times, which takes a long time to operate and has poor operability. In particular, when designating a point such as a destination required for the route search process, first display a map image including the destination, and then move the cursor to a specific position on the map image corresponding to the destination. However, it is not easy to quickly and accurately move the cursor on the screen, and the operability is poor from this point as well.

Further, when the driver or the like comes up with an idea to be recorded during the driving operation, it is necessary to temporarily stop the driving operation, stop the vehicle, and then store it in a memo pad or the like. Some recent navigation devices have a voice recognition function, but this voice recognition function is for operating the navigation device main body, and does not have a function for storing memos. In particular, it was impossible to write down an idea that came up during driving operation on a highway or the like, and sometimes it was not possible to memorize the idea.

[0008] The present invention has been made in view of the above points, and an object of the present invention is to simplify the connection between a portable information terminal device and a navigation device owned by a user, and to establish a connection between these devices. It is intended to share common functions and user information and to provide a user-friendly device.

[0009]

SUMMARY OF THE INVENTION According to the present invention, there is provided a navigation apparatus which uses a portable information terminal as a display section of a navigation apparatus for displaying detailed map information on the position of the vehicle and its surroundings. This is achieved by providing the connection means. With this configuration, the display unit of the portable information terminal device can be used as the display unit of the navigation device, so that it is possible to reduce redundant investment in the same type of information terminal device and to provide the display device of the navigation device. The user information in the portable information terminal device and the user information in the navigation device can be shared via the connection means with the portable information terminal device.
