Cobra NAV ONE 4500


Talk about seeing the big picture. Cobra Electronics' NavOne 4500 portable GPS navigation system ($929.95 direct) sports a 5-inch, 320by-240 pixel touch screen that makes it a lot easier to see your desired route at a glance. The device includes a...

Large 5-inch screen. Excellent Points-of-Interest database. Integrated live traffic data

Limited routing options. Routes generated seemed less optimal than routes to same destinations generated by competing products

The NavOne 4500's 5-inch screen and integrated live traffic data set it apart from other GPS devices, but its lack of routing options and indirect route suggestions are disappointing.

The Cobra NavOne 4500 features a large screen, an accurate receiver, and a quick satellite lock. It also has a traffic receiver, but you must live in a serviceable city to take advantage of it.

Real-time traffic updates, highly detailed maps, and a beautiful 5-inch color touch screen give the Cobra NavOne 4500 bragging rights as one of the hottest vehicle-navigation systems around.

The Cobra NavOne 4500 car GPS arrived for review at the GPS Lodge, and wow is this BIG. It is strikingly huge with its bright 5" screen and is heavy look and feel. The design is somewhat retro with its chrome trim and its sharper defined edges. ...
