But with such a wide range of features and price tags, choices can be overwhelming.

• What type of conditions do you navigate in your car?
• What is your price range ($100 - $800)?

Handheld GPS. Devices used for outdoor activities like golfing and hiking

Marine GPS. Devices used for boating or fishing

Go Mainstream

Though there are hundreds of GPS units available, there are a few reputable manufacturers that provide quality, selection and service.

Below is a list of some of the top models.

• Garmin is the oldest and most popular brand on the market. Garmin has a large selection of models with simple interfaces and easy-to-use menus.
• Tom Tom is second in popularity, offering a good variety of user-friendly GPS models and excellent customization capabilities.
• Magellan is next in popularity, offering a good product line aimed at the everyday user.

Features That Matter Most

Visit a store to handle and experience the different GPS devices manually, even if you research online. Review the different features and decide what you need.

Screen Size & Resolution. A primary consideration is the size and clarity of the screen.

Map Set & Updates. A GPS cannot provide much help if the map sets are not updated regularly. There is usually a fee associated with map updates, but some models offer free or low-cost options.

Traffic Updates & Route Optimization. If you live in a metropolitan area or drive interstate highways, this feature helps avoid traffic problems.

Bluetooth. Many states restrict the use of cell phones while driving, making Bluetooth safe and essential.

Receiver Sensitivity. High signal sensitivity provides superior reception in places where it may be challenging — driving among skyscrapers, in forests or canyons.

Lane Guidance. This feature provides realistic graphics to simulate the road and exits, providing helpful insight right down to the proper lane.

Automotive GPS

Note: Before buying an automotive GPS, consider the merits of a portable vs. a built-in model. A portable GPS mounts in the vehicle on the windshield or dashboard via a bracket or suction cups.

There are other features available with automotive GPS models:

Points of Interest. The POI feature identifies fun and useful places along the way, like theaters, hospitals, hotels, restaurants, ATMs, gas stations, and fishing spots.

Spoken Street Names. Most GPS models offer audible directions. The difference is that cheaper devices may instruct you to “turn right, 100 yards,” while the higher-end models with text-to-speech provide more detailed instructions like “turn right, 100 yards, onto Maple Street.”

3-D Building Graphics. 3-D graphics greatly enhance the navigation experience, providing a more vivid map.

MP3 & Audio Book Player. While not a replacement for your MP3 or iPod, consider this option if you listen to audio books or drive a lot.

Memory/Map Storage Capacity. Storage size can vary greatly by model. If you prefer detailed maps, your GPS unit needs adequate storage capacity.

Portability. Some portable GPS models are about the size of a wallet and weigh less than half a pound, while others can be as large as a book and weigh over two pounds

Batteries & Chargers. All GPS devices are easily powered when mounted in a vehicle. Portable units come with built-in rechargeable batteries. Look for a model operating at least three hours on a charge.

Mounting. In-dashboard models need to be installed by a qualified technician. Portable models are available with a variety of mounting options on the dash or windshield. Windshield-mounted GPS units are restricted in some states.

Handheld GPS

These mobile models are designed for recreational and non-automotive uses. Handheld units are rugged and programmable and most feature small screens that show detailed landscapes and topographic maps.

Fitness GPS. Look for a compact, rugged, waterproof unit that provides vital signs with enough memory to meet your mapping needs.

Golf & Range Finders — look for these basics:

• High sensitivity showing exact yardage to fairways, greens, and hazards
• Preloaded maps and practical updates
• Compliance with USGA rules

Hunting & Hiking GPS. While these units don’t provide turn-by-turn or spoken instructions, they should show major bodies of water, cities, highways and coastlines.

Tracking & Safety GPS. These are useful for child safety and locating pets. Key features include:

• Prompt location alerts
• Compact Size
• Water resistant
• Long-life battery
• A durable and secure attachment for pets
• Continuous Tracking

Motorcycle GPS. These units are similar to other handheld GPS units, with some features unique to motorcycling:

• Weatherproof casing
• Touch screen with glove option
• Vibration resistance

Marine & Fish Finder GPS. Avid boaters and fishermen will find these units indispensable, whether portable or permanently mounted on the boat. Key features include:

• Water-resistant case
• Screen with night watch and sunlight modes
• Effective fish locator
• Availability of fishing tables and charting maps
• Optional capabilities like course alarm, water depth and temperature
• Antenna requirements
• Ability to update from computer
