A GPS unit is a must-have gadget these days, but it’s important to know how to pick the right one as they can be quite pricy. Here are some useful pointers on what to look for.

The day of the printed map has come and gone, just like the steam train and the black-and-white TV. To find your way around nowadays, a GPS device is your best bet. Unlike the paper maps you used to use, your GPS will show you precisely where you are and give you detailed directions for getting to your destination, down to the last turn.

It can tell you where to find a gas station, a coffee shop or an ATM along the way, in addition to supplying minute-by-minute information to help you steer clear of traffic jams and highway pileups. Imagine having your own MapQuest in your car or your pocket – that’s what owning a GPS does for you. Now you can travel secure in the knowledge that you will always find your way, and get there on time.

GPS devices come in many different formats, including personal organizers and cell phones. You might, in fact, find it more economical to buy a GPS-enabled cell phone and a GPS service subscription than a standalone unit.

However, this guide focuses on dedicated GPS devices, and in particular on those designed to be used in your car or while walking.
