2. Description of Related Art

[0002] As the living quality and economic status are being upgraded, many people start to care more about the relaxation activity. Except for the indoor exercise, traveling to different places is a popular recreation nowadays during the holidays. However, while traveling, it is very easy to get lost in a strange place even with a map, and therefore, the GPS has been developed. The GPS uses a satellite to position and calculate time, and there are two the caesium beam atomic clocks and a rubidium atomic clock in the satellite for providing the precise data of latitude and longitude to enable a user to learn the position of the present location. The GPS mostly are used for precisely positioning and synchronizing within the network. Because the satellites transmit a time signal simultaneously, the worldwide network systems can obtain a stable synchronized signal source. So many products available on the market are developed in simple and stably to as synchronizing signal sources. A GPS signal receiving device usually can receive signals from a plurality of satellites for positioning and choosing the best quality time signal among all. Thus, the user won't get lost while traveling in a strange place with the GPS signal receiving device.

[0003] However, the prior art GPS only provides the coordinates for positioning, and some GPS combine with FM or some GPS combine with GPRS. Thus, the user has to transmit the related information of the desired area to the system host, for example, to renew a map or to provide traveling information of the present location, to allow the system host to find the information of the desired area and further transmit back to the user. Meanwhile, the system host charges the user according to the information provided upon the user's inquiry. However, the other related detailed information, for example, the tourist attractions, the local cuisines, hotel and so on, can't be provided on time and is not completed. As a result, the user also has to search the above related information after being directed by GPS to the desired area.

[0004] Accordingly, the conventional searching method using GPS has the following defects.

1. The GPS only provides the satellite coordinates, but not the information related to the desired area.

2. Every region has its own traveling information, and the user has to purchase a map when entering to a new area. Therefore, it is inconvenient and expensive to the user, and preserving the maps can also be a problem to the user.

3. There are always differences existing between the local tourism map and the actual routes. This can easily make the user in a wrong location.

4. The user usually has to take the winding and tiny paths to reach the tourist attractions, and new tourist attractions are generally unknown to the system host, so the user can barely receive the renewed and updated information through the GPS.

5. The defect of the passive dual-directional communication between the user and the system host, which the user transmits the related information to the system host to enable the system host provide the desired information accordingly, not only affects the user during driving but also pays the extra fee to the system host.

[0005] Thus, it is desirable to resolve the problems of using the above conventional GPS. Therefore, how to overcome the defects of the conventional design is an important issue for the manufacturer in the field.
