What you’re looking at here is probably one of the first in-car GPS navigation systems in the world; designed in 1930′s. Of course it is probably better to call this map guidance tool since this device had nothing to do with giving directions or geostationary satellites.
(Possibly) called Iter Avto, this tool scrolled through a paper map depending on the speed of your vehicle. And if you ever wanted to make a turn into a new street you’d have to find the scroll paper for that street and quickly swap it in.
Very similar to Plus Fours Routefinder first used in the U.K. about a decade ago.
