Cobra GPSM 4000 Nav One

The Cobra GPSM 4000 Nav One has almost as many features as the Garmin nĂ¼vi 880. The Cobra model is priced a little higher than the Garmin, but if you shop around a little you might even be able to find it at a much lower price. The Cobra GPSM 4000 Nav One offers voice guidance, so you don't have to take your eyes off the road to study the screen. A trip log tells you where you've been and a large points-of-interest database lets you identify destinations by name. The 5-inch (12.7-centimeter) color display is one of the largest available in the under $1,000 category, and reviewers consistently find it bright and readable.

Cobra offers an optional traffic receiver and antenna that brings in real-time updates on traffic conditions, including accidents, construction and road closings so that you can calculate alternate routes. The MSRP of $999 is a bit intimidating for most consumers; however, if you take the time to do your research, you'll find retailers and mail order outlets that offer it for less than a third of that price.
