Step1
Know what you want the GPS receiver for. If you want a GPS system for driving, you'll probably want a different receiver than if you want to go geocaching. Having an idea of the main purpose for the receiver can narrow down the possibilities.
Step2
Make a list of the functions that you want the GPS unit to be able to do. Some handheld receivers will only give you latitude and longitude, but you may also want altitude. Consider what information you want your GPS receiver to provide you with and what other information you'd like if you can get it within your price range.
Step3
Set a budget. GPS receivers vary widely in price. Simple handheld units can often be found for under $100, but you can spend a great deal more than that on a dash board system for your car. Knowing in advance how much you can afford also helps narrow down the potential choices.
Step4
See the receivers in person. A receiver only works as well as you can read and understand it. Make sure the display is clear for you from the distance you'll be looking at it and that any audible instructions are also clear. Test the buttons to see whether they are the right size for your preferences.
Step5
Rent a GPS unit or try one out first. If you're thinking about a GPS receiver for your car, rent one along with a rental car on your next trip to try it out. Ask friends and relatives if you can see their receivers and try them. Getting hands on experience can tell you whether a particular unit is right for you.
Step6
Read the reviews and ask for opinions. If you're buying a GPS for a particular sport or activity, ask others which receivers they use for the same activities. Find out the pros and cons for the unit when it's used for the particular activity you'll be using it for.
