Unless you've been living under a rock, surely have heard of the World Positioning System or GPS. There is a GPS for almost everyone, for hikers, motorists, cyclists, etc. You will also find GPS modules on some phones advanced phones like the Nokia 6110 Navigator.

What is it?

In very simple terms, Positioning System (GPS) uses radio signals from 4 satellites to locate the exact position of anything on Earth.

How much?

Apart from the cost of buying one, using a GPS is free. In fact, some of the most basic GPS not only what it is: guide the driver from A to B through a graphical interface.

The latest models come with a range of features (MP3 player, slide show, VCR, blue tooth, and even digital TV!).

Some have pre-installed GPS POI (points of interest) such as garages, restaurants, parking and more GPS manufacturers have also added a new value added services such as traffic updates in real time or time weather services like TomTom GO 530/730/930).

You need a subscription to most services, however. Typically An annual subscription costs about $ 50 with unlimited updates.

Other options are free for a limited period of time (eg when a new map becomes available within 30 days of purchase of a new GPS, TomTom allows you to download the free map).

What to look for?

Ease of use. If you are not too comfortable with gadgets, you might prefer to go to a simple model. One simply guides from A to B without all the extras.

Traffic information. Some GPS offers real-time information on traffic jams or road works. The GPS will recalculate your route – and offers an alternative solution. These services are often charged so it's best to check before buying!

Cameras speed. Most GPS come with a preset list of speed cameras. And here again, you will need some form of subscription to this list date with new cameras.

Maps. Some doctors only cover a limited geographic area. Others have larger maps as Tomtom Go 730. This type is especially useful for holidays abroad. New maps can also be purchased as a CD-ROM or pre-loaded memory cards.

You can also download the site of most GPS manufacturers. After downloading, then transfer the maps to the GPS using a memory card, a USB cable or Bluetooth kit (if GPS has Bluetooth).

Screen size. This usually varies between 3.6 to 4.3 inches. Standard, such as, especially for GPS, on-screen information should not be too difficult to read. But this should not be a problem taking in mind that most new GPS come with voice instructions.
