Everyone gets lost, but while some people depend on maps or the kindness of strangers to find their way, we prefer GPS navigators. The high-tech devices are available at increasingly low prices, and you can get one that has simple navigational features or, if you want to pony up the cash, you can snap up a fancier unit with bells and whistles like a digital camera or MP3 player.

 

If you're in the market for a GPS unit, there are a few things to look for. First, figure out what you want the device to do. If you're simply looking for a location-finder, you'll likely pay about $300 (the lower end). But if you want extra features like Bluetooth, an MP3 player, or a PDA-type device that comes with GPS, expect to pay closer to $500 or more.

 

Second, research the device's expansion possibilities and the types of maps that are included with the unit. How big is the navigator's hard drive? What kinds of content can you download, and how much does it cost? Are there any services you'll need or want to subscribe to in addition to buying the unit?

 

Third, don't be shy about trying units out at a store, even if you want to purchase online. See if there are multiple route options, multiple views for looking at directions, and whether the unit automatically re-routes you if you make a driving error. Also make sure the directions are easy to understand. After all, if you can't understand the unit's directions while you're completely stationary in front of it, it won't be much help on the road.
