If you are planning your summer holiday or even a weekend getaway, a GPS unit can really help get you where you're going.

But not all satellite-positioning devices are created equal.

If you're shopping for one, look for the kind that doesn't just say turn right, but tells you the name of the street.

It is also easier to use brands with a "smart keyboard." This technology highlights the letters as you start to enter an address, narrowing your choices.

Be sure to get a GPS with a rigid mount. It offers more stability.

As for a screen, widescreens are easier to program and view.

Some GPS brands even provide real-time traffic reports, while others let you talk on the phone hands-free.

These features do cost more, but Consumer Reports' tests found you don't have to buy an expensive GPS to get you where you're going.

Consumer Reports recommends two Garmins brands for under $400. The Garmin Nuvi 350 has a built-in trip computer and an MP3 player. The Garmin NUVI 260, which is as little less expensive, comes with a photo viewer.

For under $200, the Tomtom One Third edition has a feature other brands do not -- you can update your own maps and share them with others.

It's a great feature at no charge and it may save you from paying for map updates.

The advantage of a portable unit is you can take it with you if you are flying somewhere and then renting a car. Just do not leave it behind.
