Most people says that the world are getting smaller, because the technology that makes people can always get connected each other. We don’t need to go to the store because right know there are online store such as amazon.com or ebay.com.

So, if we the world is getting smaller, why do we need a GPS ? We need it because the world is getting crowded and complex. In the older day we need a map to find a way to another place, but these days, forget about a map, a GPS can replace any other maps.

Just enter a postal code of destination and a GPS can guide us into correct direction. It’s like having a personal guidance that take us to place of interest in nearby areas. A GPS also helps us to calculate a distance and set us on the right route.

Some system act like a wireless phone with microphone and dual speakers. Some system come with the touch screen. When we caught in a traffic jam, the system can give us alternate route, so we can escape the traffic or road block. By giving us a traffic update, it can avoid us from bad roads. Also the important one is, it can act like a weather man and warns about climate to avoid accident.

Some GPS is built in speed camera alerts that work during day and night. Some of these device work on rechargeable ion batteries. The GPS is a traveler’s mate !
