Abstract
The invention provides a method for cell phone application to start vehicle-mounted navigator through a 3G passage. The cell phone application sends a target position to a backstage in an encryption mode. A backstage server can automatically generate POI data according to the target position information, and sends the data to a data monitoring server of a vehicle-mounted system in an encryption mode. The vehicle-mounted system analyzes the data and then starts the navigator after receiving the data, and finally generates a map route. The method can be used for communication through the 3G passage and the cell phone backstage server. After obtaining the target position information of the cell phone backstage server, the vehicle system can automatically start the navigator and then generates the map route according to the target position coordinate, thus, a user can drive to the target position according to the route.
