There was also an odograph-based device with way plotter in Jeep during World War 2: http://jeepdraw.com/pauls.html

This older one from 1927 had a scrolling wristwatch-like device that required driver to turn it manually. These rolls had to be installed before the drive: https://gajitz.com/scrolling-down-the-highway-vintage-1927-analog-gps/
