Early Technology: Jones Live Map world's first GPS 1909

Jones Live Map Metre brass with glass cover,ebonite back (with one crack which desn't effect its fnctioning) complete with its leather carrying case. diameter 8.5" (22 cm). I quote from an article in the Saturday Evening Post http://www.saturdayeveningpost.com/2012/02/04/history/post-perspective/gps-1909.html
In the early days of motoring there was the challenge of navigating. Road signs were rare and often incorrect. Travellers were frequently reduced to driving from one roadside stranger to the next, gathering a few miles of directions at a time. The earliest road maps by Rand McNally were printed only after 1904. Yet a high-tech alternative appeared in 1909: a real-time, on-board directional guide called the Jones Live Map. It was invented by J. W. Jones, who had also introduced the Jones Speedometer, the Jones Disc Phonograph Record, and the Jones Yobel —“the gentlemen’s automobile horn.” The idea was revolutionary. The Live Map was a small turntable device with a cable that attached to an automobile’s odometer. Before making their journeys, drivers would purchase paper discs with the route to their destination prescribed by The Touring Club of America. At the beginning of the journey, the driver would place his journey’s disc to the Live Map’s turntable so that the journey’s starting point lined up with an arrow indicator on the glass cover. As the car began rolling, the turning odometer cable caused the map to rotate. The arrow would point to the driver’s changing position in the journey. Each disc had up to 100 miles of travel details around its perimeter. If the journey was longer than 100 miles, the driver would replace the first disc with a second, or third part. A Saturday Evening Post advertisement for the device described it as the phonograph of the road. It has disc records covering the roads of the entire world. You insert the record of the trip you want to make. The Live-Map “plays” it. Not out loud, but with a pointer that always points the way—that tells you where you are now and what to do about it. To have it with you is like having in your car a man who knows every road, every corner, every crossing, every landmark, every puzzling fork and crossroad in the entire world. A 1910 booklet, “The Jones Live Map – What Happens Without It” brags that the Jones Live Map would save the driver from the Evil Genius of the Roads, the stranger who always gave incorrect directions. It was superior to route books, which were hard to follow and led drivers into unlisted trolley and rail-road crossings. And it was more convenient than the large, clumsy, original maps that could never be refolded and were always tearing in the wind. However, the problem with this first GPS was the same that plagues such systems today. Roadways are in a state of continual change. Every time the Live Map offered printed directions like “take a right at the fork by the flag pole,” it was fighting a losing battle. Landmarks like flag poles could be removed at any time. The map discs might be corrected and reprinted, but a driver’s old discs, which relied on missing landmarks, could be close to useless.
