You want a portable GPS for your car. But there are so many new units and new feature, you don’t know what you should get. Look to GPS reviews to put you on the fast track to a decision you’ll be happy with.

Here are 3 tips:

1. Don’t rely on just the big gps sites If you want to get information and make a decision quick, the internet is the best place to find a car GPS review

. A simple search in a search engine for ‘car GPS review’ should bring up a large number of results. Paradoxically, the big gps sites (gpslodge, gpsmagazine, etc) and the big desktop sites

(PC World, Mag, Cnet) often aren’t your best source of info. They’re filled with single reviews of the latest and greatest which makes it hard to compare.

2. Be critical of what you’re reading Every site you’ll read is making money from the gps merchants, either through ads on the site or from taking a small cut of every sale. That’s not a problem in itself.

Just make sure the site reviews enough gps models that they have their bets spread out and can afford to be unbiased - they aren’t pushing the one that makes them the biggest commission.

3. Look for both expert and user reviews. Users often want something different from the experts.

Experts have depth of experience, current knowledge, and - sometimes - rigorous testing methods. Consumers, on the other hand, use the gps system for weeks not hours, learn the ins and outs, and have a personal investment in the performance. It’s two perspectives you can benefit from.

A car GPS review is an extremely useful tool for determining which GPS system is the one for you. And the search can be bewildering.
