<p>An electronic interactive communication system and method is disclosed. Software controls and a control manager resides on a unit (20, 22, 24) that communicates with a central location. The central location (16) transmits information to the unit. The information, or data, may reside in a database (30) at the central location. A number of different units (20, 22, 24) receive data from the central location's transmission source to update or manipulate data already on the units. The system exchanges data from the units to the central location (16) using a narrow bandwidth. The unit includes a transceiver and a processor. The unit also includes a display to display the data to the user after the received data has been associated with the stored data . For example, received data is overlaid on a map being displayed on the unit.</p> |
