gps in 1932? global positioning system uses satellites. What is that device in the picture?
Answer
It didn't have voice prompts and GPS.
The screen manually scrolls paper maps that are attached to a cable similar to a modern mechanical speedometer. The scroll rate of the map is proportional to vehicle's speed.
