A pre-GPS route tracking device for automobiles developed by Touring Club Italiano in the 1930s. Routes were printed on scrolls. At the beginning of the trip, the driver selected one and inserted it into a device attached to the dashboard. The route scrolled past a window in the device at a speed controlled by the car's speedometer. The maps highlighted gas stations, railroad crossings, bridges, and other points of interest. However, if you made a wrong turn, you were on your own.

Iter Auto was a solution to a real need, but it took another 60 years for the technology and infrastructure to catch up. The basic user experience was not that different from modern devices. However, implementation would depend on huge investments in cellular networks, GPS satellites, and computers, each of which were developed for different reasons, none of which included private automobile navigation.
