There is nothing more annoying than going somewhere and getting lost half way, and you either have to turn around and go back to where you came from or call someone and ask for directions. But then there is a possibility of the call, what if you have no airtime on your cellphone to call and there are no public telephones around? This is always a problem for some people, but now there's a solution.
A GPS (global, positioning system) Sat Nav (satellite navigation) system uses satellites to show you exactly where you are and where you need to go to get to your destination. This device can be installed in your vehicle. You can enter a street name, city or town, and the voice activated system will tell you where you need to go, there will also be a visual map on the screen if you get stuck or need more precise directions.
There are many of these Sat Nav systems available, but the latest one is portable so it can be transferred from car to car. You will never be stuck again! This device is great for when you have to travel to a place that you are not familiar with, you won't need to stop on the side of the road and waste time by looking through confusing map books or have to rely on road signs, the answer is right in your car, speaking to you and showing you a relevant map of where you have to turn!
Many say that this is the best invention since cars' itself as it takes the stress and worry out of traveling. Now you can also be at your destination on time and get their safely as you won't have to stop on the side of the road or ask pedestrians for directions. You will be taken straight to your destination.
