Abstract
There is disclosed a global positioning system electronic card capable of dynamically plugging navigation information, which includes a multi-interface controller, a dynamic insertion/removal card interface for being dynamically inserted with a memory card stored with map data, a GPS module, and a host interface. When the memory card is inserted into the dynamic insertion/removal card interface, the dynamic insertion/removal card interface notifies the multi-interface controller for further informing the host device through the host interface to read the map data in the memory card, thereby displaying a corresponding map. After determining the positioning coordinate, the GPS module notifies the multi-interface controller for further informing the host device through the host interface to read the positioning coordinate determined by the GPS module, which is compared with the map data read previously, thereby labeling a coordinate position on the map.
