As GPS units are included in many brand new vehicles, they are becoming more popular than ever on dealer lots. Before they were installed in new vehicles, GPS systems had to be purchased as separate units from electronic stores and mounted on a dashboard holder for use. GPS systems can be used not only for navigating your way around town, but also to track the speed of your vehicle over an extended period of time. A recent study released by GPS maker TomTom, claims that most drivers in the United States are actually obeying speed limit laws in their driving areas. Impressive!
