If you want to be able to get around town or travel long distances without a map, you may be interested in purchasing a global positioning system, or GPS device, to help with directions and traffic information. This guide on how to choose a GPS unit will help you determine which model is right for you.

• If you plan on using your system often, spend the extra money to get a unit with a mapping feature, even though it costs a bit more.

There are many different types of GPS units on the market, and sometimes the choices can get overwhelming. Following the steps below will help you make an informed decision when making your purchase.

Before setting out to the store, have a maximum amount that you will spend on your GPS device. The amount you set will vary according to how much you will be depending on the unit, as well as how many features you need. Once you have the price set in your mind, it will be easier not to get influenced by salespeople or flashy designs.

Is your GPS unit going to be used exclusively while you are driving? If so, an automobile-mounted system may be best, as it has less chance of getting lost, stolen or broken. Screens are also larger, for easier reading while on the road.

• If, however, you tend to look things up when you are not in your vehicle, consider a handheld device that features better portability.

If you want the best precision, it is wise to go with a trusted name. It may cost a bit more, but if you tend to rely on maps and directions to avoid getting lost, it is well worth it.
