One of the earliest analog car navigation systems- The “Iter Avto” (1932) [436×581]

Developed in Italy, this device didn’t use satellites (which obviously didn’t exist yet). Instead, it was physically tethered to the car’s speedometer. As the car moved, the mechanical cable rolled a paper map across the screen at a speed proportional to the vehicle’s pace.

If the driver made a wrong turn or left the designated route, the device had no way of knowing, forcing the driver to manually adjust or change the map roll.

Reckon it could’ve been a bit more useful if it correlated to the steering of the wheel. Could’ve had a mechanism to turn the map/rotate it with the steering wheel. But still massively cool.
