Have you ever used GPS?

I hate to tell you what my first one cost. I do use it an frequently. I am in Real Estate and no matter how well I know an area, those little off streets and cul-de-sacs could make you crazy. I do not have the time or patience anymore to use the street maps, although I do still have them in my car. The new one I have now even has traffic updates and it cost so much less than my first one and is more advanced. You know how fast they update electronics. We use it when we travel along with my using it for work. A this point it is as important to me as my cell phone. I do not see any disadvantages, but it does take trial and error while you are learning to use it. The signal comes from the satelites.

GPS devices are very helpful. But i still use maps to find my way to another place. It is really expensive for me. I have never used one, but i saw some freinds use theirs and they still back it up with printed maps and directions. i wonder why.

I have never used a GPS but i have see one and i have see how a GPS works but i have never used one!! lol but some day i will maybe have one or use one :D. well have a nice day and hope you will have a very good weekend! ;) see you soon and bye bye :D

GPS technology was delevoped for war by Department of Defense, United States of America. It uses 24 satellites at which the GPS Receiver gets the signal from and calculate the position. In order to get a position (coordinate), signal from at least 3 satellites are required. Although, it was meant for military, Department of Defense said that they have new technology and now releasing the GPS system for public use (before this, military have a choice to turn off the GPS system to avoid public use). I'm currently using Garmin etrex Vista Cx which cost me around USD130 back in 2006. I really impressed with the performance of the GPS Receivers especially when you are looking for direction to a place. With the turn-by-turn instruction, I've never lost again. :-))
