When the terminal calculation GPS position information is received from the mobile communication terminal 1100, the cradle controller 1250 may generate the GPS guide information using the terminal calculation GPS position information. When the GPS module of the holder 1200 is implemented as a low-cost product to reduce the manufacturing cost, since the terminal output GPS location information is more accurate than the cradle output GPS location information, the terminal output GPS location information is not used. To generate GPS guidance information. However, if the terminal calculation GPS position information is not received from the mobile communication terminal 1100, the GPS guide information may be generated using the cradle calculation GPS position information. When the mobile communication terminal 1100 is not connected to the short-range wireless communication, the GPS guide information is generated using the cradle-calculated GPS position information calculated by the cradle 1200 itself. For reference, when generating GPS guide information, a distance to a specific facility may be calculated based on the current location by using a facility location database that stores information about location points of facilities such as an intermittent camera.

Meanwhile, when short-range wireless communication is completed between the terminal cradle 1200 and the mobile communication terminal 1100, the cradle controller 1250 requests the mobile terminal 1100 to calculate GPS location information and updates the GPS location information. do. After that, the terminal continuously receives and updates the GPS position information from the mobile communication terminal 1100.

On the other hand, the terminal holder 1200 may include an alarm light (1260) to be turned on by varying the lighting form according to the terminal interlocking mode, the terminal non-interlocking mode and the speed. For example, the terminal lights up in blue in the interlocking mode, and the terminal lights up in red in the non-interlocking mode. In addition, when the vehicle speed exceeds the speed limit, the alarm light 1260 may warn the user by performing a flashing of lighting on / off. The vehicle speed is calculated from the GPS location information, and when the vehicle speed exceeds the speed limit on the current road, the vehicle blinks to warn the user. Therefore, the vehicle's current speed can be visually displayed whether the vehicle is running at a constant speed or overspeed. For example, when the vehicle current speed is a constant speed that does not exceed the speed limit, the alarm light 1260 is displayed in green. On the contrary, when the vehicle current speed exceeds the speed limit, the alarm light 1260 is red. You can make it blink.
