That's it! But the history channel said 1912. Here's how it worked:
It was a small device that attached to the odometer. A motorist would purchase a cardboard disk with directions on it. The disk was fitted to the device and rotated as the odometer progressed. As the disk rotated, a pointer on the device to the directions printed on the disk showed the motorist when and which direction to go at each junction. Of course, the disks were directions from city to city rather than door to door as today's. At the time there were no road signs, road maps or route numbers. So with the implementation of those, this device became obsolete – until electronics took over.
