With its sprawling 5-inch, easy-to-read display, the Nav One 5000 from Cobra is a sight for sore, road-weary eyes. Although it boasts the same-size screen as its predecessor, the Nav One 4500, the 5000 offers better routing options and more robust trip-planning abilities. This feature-filled GPS can also help you sidestep tickets with its built-in database of traffic-light and speed-camera locations. Not without shortcomings, this navigation system is big and heavy, and its hands-free Bluetooth/cell-phone feature could be improved. Still, if you're in the market for an easy-to-use GPS that you'll have no problem seeing, the big Nav One 5000 is worth a look.
