Navigational and GPS Device Buying Guide

If you wind up frequently getting lost while driving around or even walking, hiking  and riding a bike , you might want to look into buying a Global Positioning System, usually referred to as a GPS device . Not just for the directionally challenged, these are great for those who don't like paper maps  or asking for directions.

These nifty contraptions come in a few main varieties, including automotive, handheld and marine. There are also GPS devices designed specifically for runners which track speed, distance and course. These devices are usually made in combination with heart rate monitors . For those who like to keep things simple, don't forget that GPS systems are also available on smartphones  and PDAs , eliminating the need to carry an arsenal of electronics with you wherever you go. In short, no matter what your needs, there is a GPS device  for you.

What to look for in a handheld GPS system:

• Weight: If you're hiking or backpacking, every ounce counts. Conversely, durability is also important.
• 12 Channel Parallel Receiver: For hikers and off-road travelers, these receivers will give the best service.
• Map Screen: Certain devices only display relative longitude and latitude lines. Be sure your model is map-ready.
• Waterproof : You don't want your GPS to short out when it rains or if you fall in a stream.
• Long Battery Life: Carrying multiple batteries around can certainly be a pain.
• Waypoints: Most sites recommend a GPS unit with storage for at least 500 waypoints.
• Compass : Helps you get to the next waypoint.
• Screen Characteristics
• Color  vs. B&W  : Some color screens are hard to read in sunlight. The exception is TransReflective Color  screens.
• Size may also be a factor. Consider how small a screen you can read comfortably.
• Route Capacity: Most devices can hold at least 20 routes, while some may hold as many as 50. The more, the better.
• Topographic Maps: If you plan to do a lot of backcountry hiking, elevation and small stream data will definitely come in handy.
• GPS Information: Click here for more information about choosing a GPS for hiking.

What to Look for in a Car GPS:

• Address to Address Routing: Essential for car navigation.
• Maps: Always look at the included maps package. If you think you will ever venture north of the border, look for a package that includes Canada or just says North America.  Take into account where you will likely be driving in the future.
• New models feature transatlantic maps if you may be road tripping in Europe.
• Verbal Directions: The best (and safest) way to use your GPS device is to have it take instructions from you and then talk back to you. Some units will also tell you when to make a turn.
• Mounting: Make sure to get a unit that can be easily mounted to your dashboard.
• Automatic Routing: Most models have this feature.
• Waypoints: Some units have just the basics (points of interest, gas stations, etc.). Others will allow you to mark your own points of interest as well.
• 12 Channel Parallel Receiver: This type of receiver will give you the best reception so that you don't lose the signal in a strange city.
• Screen: You want a decently large screen since you might need to glance at it while driving.
• If you get a color screen, consider a Transreflective Color screen.
• MP3 Player: Some GPS devices can double as MP3 players if you're bored with the radio and tired of lugging around your CD collection.
• Audio Book Playback: Many of Garmin's models and some of TomTom's have the ability to play audio books, which can make that longer trip that much less taxing.
• Satellite Radio: For just $12.95 per month, users can stream XM Radio to their Garmin device, while Clarion's NICE gets Sirius radio for a comparable fee.
• GPS Information: More information about buying a GPS device for your car.
• Also check out the comparison of several models in different lighting conditions for brightness and readability.

Major Manufacturers

• Sanyo 
• TomTom 
• Nuvi 
• Clarion 
• Garmin 
• Magellan 
• Pharos 

Garmin Nuvi 775T 

Among the many features of the Nuvi 775T is the 3D buildings display.  Buildings are rendered in cities, which is especially helpful in larger, metropolitan areas. The lane assist feature gives a realistc 3D redering of critical road signs and exits so you never miss a turn. What seperates this model from the 765T  is that this unit comes loaded with maps of Europe. 

TomTom GO 930T 

This is TomTom's premier model.  It includes transatlantic maps, voice recognition, remote control, and a traffic reciever among its many features.  TomTom's IQ routes is a collection of data from millions of drivers to find the quickest routes possible.  So you can drive like a local in any city, even in Europe.

Garmin Nuvi 1690 

Each nuvi 1690 comes with a free 2-year nuLink! subscription and includes Google local search to find local restaurants, landmarks, and attractions. The 1690 also includes preloaded maps, lane assist with junction view, hands-free calling and ecoRoute.

Navman N40i 

The Navman N40i, brother of the N60i  (slightly upgraded model) has a few noteworthy features including the ability to take a photo of any location so that no matter where you end up, you can always find your way back to it. There is also a quick "get gas/find parking" button and a safety camera sensor to help you avoid getting speeding tickets. Finally, like many new models, there is a traffic sensor updated in real time to keep you out of traffic and on your way.

TomTom One 

Finally a GPS device for everyone! The TomTom One is great for your automobile. What's more is that this unit has a touch screen that you can access. For added safety, the 3.5" LCD screen only appears when stopped. However, the voice commands are wirelessly transmitted to a Bluetooth  headset.

HP iPAQ rx5900 

The HP iPAQ rx5900 is a PDA/GPS device based on Windows Mobile 5.0 in a functional fashionable form. The compact unit allows you to listen to MP3s, watch videos, look at pictures, play games or surf the Web while stuck in traffic. Ideal for use in the car since the measly 90 minutes of battery life makes it unsuitable otherwise. The quality of navigation system is what really makes this unit shine.

iCN 750 

The Navman iCN 750 lets users take digital snapshots of locations and display them for navigational help. Though the quality is poor, the iCN's geocode system can save that picture's location and bring it up as a landmark tool at the user's request.

Sanyo NV-E7500 

This GPS and DVD  combo acts as a media player and a portable navigation device. The 7" screen is comparable to many other portable DVD player screens and its stereo speakers, while not stellar, get the job done. The Sanyo can also play CDs.

Garmin Edge 350 

The Garmin Edge 350 is a GPS device designed especially for bikers. Like its TomTom and Magellan competitors, the Edge 350 clips onto a bike's handles for easy access. In addition to regular features, also tracks heart rate, speed and other exercise features.
