Auto GPS Buying Guide

Dorothy Gale had it easy—she needed only to follow the yellow brick road to find her way to the Emerald City. Now, thanks to the increasing affordability of Global Positioning System (GPS) devices, we have it just as easy if not easier. With features like turn-by-turn directions and voice prompts, finding your way to and from your destination is akin to clicking your heels three times. Developed by the US Department of Defense for military tactics, GPS technology is a 24/7 radio navigation system that identifies and tracks the location of the GPS device virtually anytime, anywhere.   GPS devices get their data from 24 satellites orbiting Earth. Locking into a minimum of three satellites determines your location in longitude and latitude. Some devices routinely lock into four satellites to provide altitude. Use of the satellite network is free—all you need is an unobstructed view of the sky, but while GPS devices will work under cloud cover and inside cars, they may falter under heavy tree canopies, inside tall buildings or tunnels, or dense urban areas with lots of skyscrapers. Pronto’s Auto GPS Buying Guide will help you select the GPS device that meets your needs (see also Handheld GPS Buying Guide).  More »

the five

What are the five key points I need to look at?



In-dash or portable
Will you need it only for your primary vehicle or do you want the flexibility to bring it with you? How often and for what purpose(s) you’ll use your GPS device will determine which option is best for you.
Interface
Look for easy-to-read displays with easy-to-navigate menus. If your device is hard to read or awkward to use, chances are you might not use it at all.
Maps and data storage
Determining how much you need your GPS to do will help narrow down which model is best for you. Do you want your device to be able to store and run other media applications?
Traffic receivers
If alternate routes around traffic or construction is a must, consider a device with a traffic receiver or purchase a separate traffic receiver (traffic data is available by paid subscription).
Options
Nice to have if you’re willing to pay for them: voice-to-text which includes street names in the audio transmission or Bluetooth capabilities that allow you to call a hotel, restaurant or other destination and keep your hands on the wheel.

Garmin Nuvi 680

Sometimes you just need to go for it!  The Nuvi 680 is the latest edition from GPS expert Garmin.  Replacing the much acclaimed Nuvi 660, the 680 is the latest edition to the 600 series of auto GPS devices that have scored consistently high for their easy of use, crystal clear display, and portability (which will ensure you won’t get lost after you’ve found a parking space). The good news, you can probably get a great deal on a 660, if you don’t want to spring for the 680 which can be had from $750-$1000 depending on warranty and accessories.

hot buzz What's the latest in the world of GPS?
According to 12 Volt News, the Wall Street Journal predicts that sales for in-vehicle navigation systems will exceed 3.3 million units this year with the CEA says that sales of aftermarket devices leaped to triple digit numbers in 2006 with more than 2.2 million new units sold.  Moreover, an online survey conducted by the latter organization shows that 24 percent of online consumers intend to purchase a GPS device within the next year and will spend an average of $410. This could result in sales of $4.1 billion in 2007.

shop talk

What are the terms and definitions I need to know about?

Basemap
Provide general coverage of cities, towns, highways and bodies of water. Most units come equipped with built-in basemaps, but units without mapping are also available. Manufacturers may also offer basemapping software that allow you to upload new or different basemaps to the device.

Points of Interest (POI)
Specific map locations, such as ATMs, gas stations, restaurants, etc. If having access to these locations is important to you, you’ll want to look for devices that can connect to your computer for geo-targeted data downloads.

Waypoints
Specific locations delivered in latitude and longitude. The more waypoints your device can store, the more accurate its navigation output. Standard GPS devices come within 10-15 meters. If you need more accuracy, look for GPS devices that support Wide Area Augmentation Systems (WAAS) or Differential GPS, both of which increase accuracy to within 3 meters.

TTFF
Time to First Fix or the time the receiver takes to find its position in a new location. The SiRF Star III GPS receiver is the de facto standard for GPS devices because of its fast TTFF and its ability to acquire/maintain a signal in denser and more urban environments.
