Five Things to Consider Before Buying a GPS System 2



Should I just use my cell phone's GPS feature, or is it worth splurging for a factory-installed GPS in my new car or a high-end portable navi unit?

It used to be a clear decision: To get a feature-rich, accurate, and user-friendly GPS navigation system, you had to spring for a factory-installed model, which is conveniently built into the dashboard of a car either by the manufacturer when you buy a new car, or by an after-market specialist. While built-in factory-installed navi systems still beat their portable brethren with certain features – large, easy-to-read-and-navigate screens, thorough travel info, and seamless integration with the rest of your car's audio -- the gap between the two is not nearly as wide as it was just two or three years ago. For one thing, many portable standalone GPS units now offer turn-by-turn directions with actual street names, robust local travel information (gas stations, parking, restaurants, etc) that's integrated into maps, and live travel updates, while even some cell-phone-based devices offer instant route recalculation if you miss a turn.

Given the potential similarity in features that's available in all three types of GPS navi units, we think it ultimately boils down to money. If you've got the money, we suggest a factory-installed system since it's optimized for your car and will integrate nicely with the dashboard (there's nothing uglier than a big cord hanging down from a big bulky portable GPS navi system stuck to your windshield).

But say you have more than one car, or an old car – in that case, we'd suggest getting one of the high-quality portable systems available from manufacturers such as Garmin, TomTom, Sony, Panasonic, Pioneer, and LG, among many others, as these generally offer you all the features you could get on pricier factory-installed systems, but cost less and can be used in more than one car (entry level $200 units give you basic directions, but lack features such as real-time traffic updates, extensive travel info, and can be slow to recalculate routes).

Cell phone GPS services are perfect for those who travel a lot and need quick directions in a pinch while occasionally in an out-of-town location, but not so good for, say, a traveling sales rep, who would benefit from the generally easier-to-use and more accurate portable systems.
