Abstract
An electronic navigation system using wirelessly tranmitted video map images from one or more ground based tranmitters together with wireless receivers having visual display available to travelers, for receiving and displaying the video map images. In one embodiment a cellular system is provided using video map images covering different zones or cells of a city or other community. GPS reception is combined to additionally provide location, direction, and speed parameters on the received video maps. Transmitted video image information may also include names of streets, roads, as well as places of interest and to obtain service and assistance in emergencies. Interactive controls are provided as supplements to assist travelers in obtaining specific information as well as additional information.
