Chicago-based Cobra Electronics in U.S. recently unveiled its new GPS navigation system, the first portable with real-time traffic information. The Nav One 4500 offers rerouting options based on the location of traffic congestion. Portable units appeal to people who want to be able to use a device in different cars, including in rental cars while on business trips or vacations. The data, refreshed every two minutes, is available for 48 major cities, including Chicago, New York, Los Angeles on down to smaller cities, including West Palm Beach, Fla., and Austin, Texas. Marsh said these cities include more than 70 percent of the U.S. population.
Roads with heavy traffic are pink and those with a moderate amounts of traffic are blue. Diamond icons represent road construction, and flag icons represent slowdowns from lane closures and flooded bridges. The Nav One 4500 has a touchscreen, which has proven popular among GPS purchasers. The original Cobra device was operated with buttons. Nav One 4500 has 7.6 million “interest points,” including restaurants, hotels, parks, beaches, churches, government offices and museums.
