Summary:

          In this article, the author talks about one of the newest features in a portable Global Positioning System GPS, which is the FM transmitter. The author mentions the differences between a portable GPS and a built in car GPS. He shows how it is easy to fix it on the dashboard and connect it to the lighter to get the power. An FM transmitter which is located in the portable GPS will send data to the FM audio in the car. Finally, we can use the portable GPS in many cars because it is light and it is easy to carry.

            I chose this article for many reasons such as scientific and personal reasons. This article is much related to my field, which is computer engineering. It talks about the portable GPS features and how to transmit and receive the signals between this device and the FM radio car. The author explains how to transmit the signal from the GPS in a low power and in a specific frequency to receive it with the audio car.  These details are much related with my subject. The second reason is a personal reason; I am very interested in the new technology especially which interacts with us in a real time. Real time devices -like portable GPS-are very useful in our lives. The author explains many points that the people prefer about the portable GPS; for example, it is cheap and also no different in the work, with the highest price GPS which is built in the car .In my country, we use the GPS but not too much like here in the USA because of the bad situation and the government and the police every week are blocking a new street and opening the other one. If we need to use this technology in my country, we should update the city maps every week. And also we do not have a huge data base to cover the big city like my city. This article added to my information new things about how to match the GPS with the radio car to get clear audio guide to your road. Before this article, I did not know what the differences were between the portable and built-in GPS in our car. Finally, I hope to use this technology frequently in my country as soon as possible(in the future).
