摘要:
A navigation system and navigation equipment which reduce the time required for radio transmissions to implement fast navigational guidance. The navigation equipment communicates bi-directionally by radio with a navigation server, thereby providing navigational guidance. The navigation equipment transmits position data delivered by a GPS receiver to the navigation server through a communication device and acquires, from the communication device, map data for display indicative of a map of a surrounding area including a self-location provided by the position data sent back from the navigation server. The navigation equipment then performs map matching between road information contained in the acquired map data for display and the position information, thereby determining a current position on the road, thereby displaying a map in the form of an image on a display unit in accordance with the map data for display and displaying the current position determined by the map matching on the map displayed in the form of an image.
