Review of GPS Devices No matter where your business travels take you, one of these GPS devices will help you find the best route to get there.

Paper maps belong in the past. New GPS technologies have put interactive, real-time digital directions within reach of any entrepreneur. A GPS device is the perfect complement to a highly mobile business lifestyle where you need to navigate unfamiliar cities and get to your destination on time. Portable GPS systems (rather than automobile built-ins) can tag along with you whether you're in the company car, flying off to pick up a rental or just getting around in your hometown.

Portable GPS units come in many flavors, including stand-alone devices and GPS built into a PDA or a cell phone. We're rounding up portable stand-alone GPS units. Look for a screen that's easy to read in daylight and for a device with preloaded maps that cover your stomping grounds so you don't have to download extra maps right off the bat.

The Magellan RoadMate 2000 is a compact unit that comes preloaded with maps of the lower 48 states, turn-by-turn voice guidance and 1.3 million points of interest such as lodging, airports and restaurants. At $399 (all prices street), it's a low-cost way to get started with a basic portable GPS system. The Lowrance iWay 350C clocks in at a similar price--$400--and also features a 3.5-inch touchscreen.
