MDIS "PathMaster" GPS Control Display Unit

In the late 1990s, Magellan released the first turn-by-turn navigation system for civilian drivers. The PathMaster hard-wired into a car, allowed users to see a map on a display screen and follow directions. The large computer received GPS data from an antenna and sent it to the display. A small card with a portable hard drive containing map data was inserted into the computer.
