How to Choose a GPS System

GPS devices are a convenience for drivers. No longer do you have to worry about carrying multiple maps with you---or folding them up. A GPS unit is not only a mapping device; it can also display traffic conditions and locations of interest, and some even have satellite radio reception.

Difficulty: Moderate

Instructions

1. Determine what you need from a GPS system. You might just need a GPS that replaces your book of maps with one on a screen. Or you might want one that includes turn-by-turn directions, or even one that includes real-time traffic information.

2. Find out whether there is a cost for map updates, and when the last time the maps for the GPS system you are purchasing were updated. Road construction is common in almost every area of the country, and having your GPS direct you down a road that no longer exists can waste a lot of your time.

3. Compare screen sizes in the store. Stand the same distance away from the screen that you will be when you're sitting in your vehicle. This can help you determine how easy the screen is to see from your seat and the size screen you will need.

4. Compare the images. Not every GPS system has the same type of map images. Some GPS systems offer only a map, without aerial images. If you do not need aerial images, selecting one without them can save you money.

5. Evaluate the extra functions of the GPS system. Some GPS systems allow you to receive satellite radio; if you are considering buying a satellite radio player this can save you some money, but if you already have one it's not necessary to pay extra for this feature in a GPS. Another feature to consider your need for is the "Points of Interest" feature, which informs you of restaurants, bars, hotels and shopping in an area. If you will be using your GPS mainly in areas you are familiar with, you might not need this feature.

6. Evaluate price and functionality. Do not just choose the cheapest unit if for a very slight increase in cost you can have one that meets all your needs and keeps you from having to purchase additional technology.

Tips & Warnings

• Keep in mind that GPS units can have reception issues in downtown areas surrounded by lots of tall buildings and in rural areas with limited satellite coverage. If most of your travel is in areas such as these, you might have to pay a premium for a company and unit with better coverage in those conditions.
• Keep in mind that a GPS device that is not easy to remove or store in an enclosed compartment in your vehicle can be attractive to thieves. If you leave it on display, it can increase the risk that your car will be broken into.
