Iter Avto First GPS

Before GPS navigators, there was the Iter Avto, which used a map on a scroll, and is believed to be the first on-board direction guide. Similar to modern devices such as a Tom Tom or Garmin, the device was positioned on the dashboard of a car, and came complete with a set of paper maps, which were wound from one roll to another across a display. A cable connected to the speedometer controlled the scroll rate. To make things easier to read, the speed at which the display moved was proportional to the speed of the car so it always showed the correct point.
