2007-05-12I'm not at all satisfied with this product. I also own Microsofts GPS and I like it very much. I had the Microsoft one first and wanted to try this to see which is better.
2007-05-09If you are a truck diver this is not for you, it help a lillte bit but it gives sometimes routes that are not good for trukers like , thru mountians even trying to choose just interstates.
2007-05-04I have owned the 2006 version of this program since it came out. I travel for a living and have used it on both coasts and in the midwest EXTENSIVELY. The ONLY thing it is good for is giving you a rough idea of how long your trip will take. THE MAPS ABSOULETLY STINK EVERYWHERE!!!!! There is a MAJOR 4 lane hiway near my home (Hwy 2 from Lincoln NE to Nebraska City, NE) that has been there for 5 to 10 years and it isnt even on the map (It still shows the old 2 lane hwy 2 and tries to redirect you OVER AND OVER AND OVER again). I have found this also in at least 2 other states. It has even directed me to the wrong TOWN!!! (In California when I was going to Stanford unviersity)
SAVE YOURSELF SOME HEADACHE AND BUY SOMETHING ELSE!!!!!
2007-04-22Delorme Earthmate LT-20 ... If I could rate this product lower than one star I would! I purchased this program thinking it was as good as it used to be in 2004. NOT! First off I was led to beleive it was ther 2007 version...it's not! It's 2006 Street Atlas. And they want $10 more to give you the 2007 SA update. That's not gonna happen! I 've tried everything I know and can't even make it open to MY city. It opens to Washington DC...I live in sourthern CA. It lists my home on a street 1/2 a mile away. personel prefferences such as POIs and info for trip planning have to be set each and EVERY time you open the program. There's no such thing as personelizing it and saving your prefferences so you can quickly set up a route knowing that all your prefferences are in place. It couldn't even find the North Rim of the Grand Canyon untill I put the latitude & longitude in for it! What good is that??? When I set up POI to find Campgrounds in a certain area, it cannot find them even when "I" put the names in....much less perform a search on it's own. This program is absolutely beyond useless. Worst money I've ever spent on a map program. I won't be buying this again!
2007-04-10I recently tried this product and found severeal problems with the result that I will be returning it under Delorme's 30 day Money Back guarentee
- It guides you by saying the name of the street or exit to take however it is sometimes difficult to understand what is said
- It does not seem to be as accurate as the navigator which is built into my Toyota. It can be off by 100 feet. By this I mean it thinks the car is located at some location point but in reality that point is 100 feet away.
- It guides you by saying something like "take a left turn at Main street that is 100 feet away" but if you are not good at judging distance and if there's no street sign or it is dark then you may miss the turn. In my Toyota, the nav makes a ping sound about 20 feet prior to the turn and before you get to that point, it will say take a left turn at sound so this makes it very easy to know when to turn
- Putting the lap top on the passenger chair and running the wire from the GPS on the dashboard to the lap top is not ideal
On the positive side, it does an ok job of routing but not as good as the built in unit.
Therefore, too many problems so will be returning it

This package of the Earthmate GPS LT-20 GPS receiver and Street Atlas USA 2005 software can turn your laptop into a powerful GPS tracking device. The GPS LT-20 is a high-performance, easy-to-use link to the satellite navigation technology of the Global Positioning System (GPS). Accessing these satellites is available for no additional charge. Earthmate, connected to a USB laptop PC, shows your real-time position on detailed Street Atlas USA maps anywhere in the U.S., so you will always know where you are and where you need to go.
Compact and Powerful
| This new GPS unit is one of the smallest on the market, measuring just 1 7/8" w x 2 5/8" h x 9/16" thick. It comes with an attached 5' cable with a suction cup on the cable designed to hold the GPS against the windshield or on the dash for optimum performance. Just plug the other end of the cable into the USB port of your laptop PC. It is best to avoid rapid and far-ranging temperature extremes, bringing the GPS indoors when not in use, just as you would a cell phone. The yellow reflective casing helps reduce high temperatures while on the dash. |  (Phone shown for size comparison only) |
Getting Started Is Easy
Plug the Earthmate GPS LT-20 into the USB port of your laptop PC. The low-power chipset draws power from your laptop, meaning no GPS batteries are needed. Install the Street Atlas USA 2005 software, and load the entire second data disc onto your hard drive if you want. The software also includes over 4 million places of interest. Place the GPS as close to your front windshield as possible, ideally using the enclosed suction cup on the attached cable to hold the GPS against the glass. Click on the software GPS tab and you'll see your position updated in real time on the maps as you drive. There are many custom GPS options included within the GPS tab.

What Is WAAS?
WAAS stands for Wide Area Augmentation System and is a system of satellites and ground stations that provide GPS signal corrections. As is true of the GPS satellites, there is no extra charge or equipment required to take advantage of WAAS. Because the new Earthmate USB GPS is WAAS-enabled, it is possible where WAAS is available to experience accuracy of under three meters for the majority of tracking time.
How WAAS Works
The system consists of roughly 25 ground reference stations positioned across the United States. These ground stations monitor GPS satellite data. Two master stations are located on each coast and these collect data from the reference stations and create a GPS correction message. This correction takes into account GPS satellite orbits, clock drift, and signal delays, typically caused by atmospheric conditions. The corrected differential message is broadcast through one of two geo-stationery satellites or satellites with a fixed equatorial position. Any WAAS-enabled GPS, such as the Earthmate USB GPS, is able to read this signal and benefit from the enhanced accuracy.
WAAS Performance Considerations
As is true for all GPS usage, the location and environment of the user will cause variability in WAAS performance. For instance, the position of the satellites over the equator make it difficult to receive the signals when mountains or trees obstruct a clear view of the horizon. Therefore, it is safe to say that WAAS provides the best performance in open-area situations. Unlike DGPS (differential GPS), WAAS does not require additional receiving equipment.
