If you're like me, choosing the right GPS receiver is a little daunting. What helps is a good GPS reviews comparison, where you can learn what various models do and how much they cost. In other words, you need a guide!

Choosing the right GPS device is critical. Prices have dropped over the past two years, and you can probably get a model with more bells and whistles than you think you can. To help you form your game plan, let's first talk about who the main manufacturers are, then what various models do and how much they cost.

There are a number of companies that make GPS receivers, but the big three are Garmin, Tom Tom, and Magellan. Garmin is the industry leader with by far the most market share, and also a much broader range of products than anyone else.

Magellan actually was one of the first companies to make these nifty little devices. They were essentially the pioneer. And Tom Tom is the new arrival. Although new, Tom Tom has made great inroads on the market shares of the more established companies by offering great products at great prices.

Any good GPS reviews comparison should tell you what you can expect to buy. So, let's run over the basic features that you'll get with any GPS receiver.

All GPS receivers have a touch screen interface, maps of the lower 48 states, and a database of Points of Interest (POIs). All receivers also calculate the best route from where you are to where you want to go, and they give you directions via spoken voice prompts.

The base models of either Garmin, Tom Tom, or Magellan will do all of this and more.

For around $150 you can get the Garmin nuvi 200, the Tom Tom One, or the Magellan Maestro 3100. These three models all cover the basic features I mentioned.

What if you want more? How much is that going to cost?

Well, let's run over what more you can get.

Upgrades are: more maps (Alaska, Hawaii, Canada, Europe, Mexico), bigger screen, Bluetooth, real-time traffic and weather, many more POIs (how about 6 million!), and multiple routing.

You can get most of this stuff for $350! For instance, the Garmin 660 can do all of the above except the multi-route calculations. It sells for slightly under $350.

Magellan's Maestro 4250 is a direct competitor and can do essentially what the Garmin 660 can. The 4250 is currently selling for slightly more than $250.

Tom Tom's comparable receiver would be the Tom Tom Go 720, which is currently selling for less than $350.

Of course, you might be willing to spend more!

As you go higher in price, each of these companies offers great proprietary features. Magellan has a deal with AAA, for instance, to include their Tour Book right in the device. (For AAA members only.)

A good GPS reviews comparison can only do so much, however.

Now you need to actually get on an informative website and start browsing.
