NAVIGATION DEVICE

摘要

The navigation device (1) displays a true image of a digitized map, and provides position information via a GPS UNIT (6). A built-in electronic compass (14) provides data to correctly orient the map display to the ground. The device receives the map image from flash memory cards or "flashcards" (10), which plug into a simple port in the device. A number of destinations, waypoints or other reference points may be stored.
