Buying a Global Positioning System (GPS) to meet your needs may not be as simple as one might think. There are a myriad of different devices, for many different purposes.

The first thing to consider when buying a GPS device is its primary use. Will you be using it on the road, on the trail, or on the water?

On the road devices are usually temporary mounted in the vehicle with suction cups or bean bags. Most of these devices have turn-by-turn instructions and auto correction if you miss a turn.

We recommend getting a device with the auto-correction feature, that way you don’t have to mess with the device if you take a wrong turn, it will recalculate the route for you automatically.

There are some devices that are also portable, so you can unplug them from your vehicle and take them with you as you walk around in a large city.

My favorite in this category is the Garmin c330, c340, and c530 series. They are a wonderful size for using it in the vehicle and small enough to use as a portable. They have city maps pre-loaded, so they are not much use off-road.

Many of the newest designs have built in picture viewers, MP3 players, traffic updates (careful, that usually costs extra!!), and many other bells and whistles.

One of the best features of the Garmin c-series line is the ability to ask for the closest landmarks, such as food, gas, shopping, golf courses, etc.
