Looks like a Sirius Radio black antenna but is yellow. Extremely accurate. Even shows whether you are close to the centerline of a road or near the outside edge. Also give your speed to 1/100th of a mph if you want. Delorme is the mapping people who did and do the US Military mappings etc. Had mobile Delorme GPS vehicle imaging on our laptops since about 2001 or 2002.
