The information capturing unit 11 can be a camera, a video camera, a keyboard or a mouse used for accessing scenic spot information 111 of a point of interest (POI) positioned by the positioning unit 12. The positioning unit 12 determines position information 122 and time information 123 of a point of interest according to a positioning message 12 received by a global positioning system (GPS). The control unit 13 can be a central processing unit (CPU) or a micro-processing unit coupled to the information capturing unit 11 and the positioning unit 12 for receiving the scenic spot information 111 and the corresponding position information 122, and generating a scenic spot release index 131 based on an identity identification message that represents the navigating device 1, wherein the identity identification message of the navigating device 1 can be a code, an ID number or an Internet protocol (IP) address IP of the navigating device 1. The input unit 16 can be a keyboard, a mouse, a voice recognition input device or a touch panel, and a user can input a category 161 of the scenic spot information 111 to the navigating device 1, and the control unit 13 generates a scenic spot release index 131 based on the category 161 inputted by the user. The storage unit 14 is coupled to control unit 13 and provided for storing map information 141, and storing the scenic spot information 111 according to a control of the control unit 13. The communication unit 15 is coupled to control unit 13 and provided for transmitting the scenic spot release index 131 to the server 2 according to a control of the control unit 13. On the other hand, the server 2 receives and stores the scenic spot release index 131.
Further, the user can input set search information 162 such as a keyword, a shopping discount, an exhibition activity, a road scene or a traffic condition from the input unit 16, or can set a range for searching the map information 141 such as searching a location within a distance of 500 meters from a building, or can specify a certain administrative region as the search scope. A user of another navigating device 3 can input set search information from an input unit and use a communication unit to transmit the set search information to the server 2. On the other hand, the server 2 receives the set search information transmitted from the other navigating device 3 and transmits a scenic spot release index 131 corresponding to the set search information to the other navigating device 3. After the communication unit of the other navigating device 3 receives the scenic spot release index 131 fed back from the server 2, the control unit marks a specific symbol corresponding to the scenic spot release index 131 in the map information, and each specific symbol represents a valid release node. Therefore, the user can select one of the symbols to request downloading the scenic spot information 111.

And then, the navigating device 4 receives a scenic spot release index 131 transmitted from the server 2, so that the user can know that the navigating device 1 has the scenic spot information 111 and can request from navigating device 1 to download the scenic spot information 111. In the meantime, the navigating device 4 becomes a download seed of the scenic spot information 111, and the navigating device 4 can upload a part of the scenic spot information 111 for sharing. In other words, of the navigating device 5 receives the scenic spot release index 131 transmitted from the server 2, so that the user can know that the navigating device 1 and the navigating device 4 have the scenic spot information 111 and request downloading the scenic spot information 111, and the navigating device 5 can download a part of the scenic spot information 111 from the navigating device 1 and the navigating device 4. In the meantime, the navigating device 5 becomes a download seed of the scenic spot information 111, and users can upload and share the scenic spot information 111 provided for the download by other navigating devices.
With reference to FIG. 3 for a schematic view of a peer-to-peer scenic information sharing navigating device in accordance with the second preferred embodiment of the present invention, a user can use a navigating device 1 to set the information of searching to a “dining” type and use feedback information of the server to know that five locations A, B, C, D and E can meet the user's required scenic spot release index. Therefore, the user can select and download the scenic spot information of the location A, B, C, D or E according to personal preference.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
Further, the user can look up or download the map of roads or building floor plans through the road service platform provided by the navigating device 1. With reference to FIG. 4 for a schematic view of a peer-to-peer scenic information sharing navigating device in accordance with the third preferred embodiment of the present invention, if a user lose direction in an airport, the user can set the navigating device 1 to search “airport” and use the feedback information of the server 2. Further, the user can obtain the map of the airport fed back from the server 2 according to the user's requirements.
With reference to FIG. 5 for a schematic view of a peer-to-peer scenic information sharing navigating device in accordance with the fourth preferred embodiment of the present invention, a traffic jam is used as an example. In FIG. 5, a driver is stuck in traffic jam, and the driver can know from navigating device 1 that a road construction is taking place in the front, and a section of the road is congested, so that the driver can select a detour to avoid the road construction site or traffic jam.
