    • 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.
    • 公开了能够动态插入导航信息的全球定位系统电子卡,其包括多接口控制器,用于动态插入存储有地图数据的存储卡的动态插入/取出卡接口,GPS模块和 主机接口。 当存储卡插入到动态插入/拔出卡接口中时,动态插入/拔出卡接口通知多接口控制器进一步通过主机接口通知主机,以读取存储卡中的地图数据,由此显示 相应的地图。 在确定定位坐标之后,GPS模块通知多接口控制器进一步通过主机接口通知主机,以读取由GPS模块确定的定位坐标,该定位坐标与先前读取的地图数据进行比较,从而标记坐标 在地图上的位置。
