Many newer cars come equipped with Global Positioning Systems (GPS), and there are other GPS options available for installation in cars that don't already have one. But -- what about the people who rarely drive? Or people who don't have room in their cars for bulky GPS add-ons? For those people with an iPhone, there's a built-in GPS application, called Maps.

Using this iPhone application, you can find a location on the map, use a compass to determine your location, or get turn-by-turn directions to where you need to go. If you'd rather not follow turn-by-turn directions, you can also see a map with a highlighted route, and follow that route.

With this great GPS application, you'll never have to worry about getting lost again. You can easily share your location with others, find an alternate route if you're stuck in traffic, or get directions to another location on the fly. Gone are the days of following a friend from one location to another. Instead, you can use your iPhone and meet him or her there.

Many times, when you're driving somewhere new and following the directions of someone else, you'll run into a closed road or new construction you have to avoid. In situations such as these, it's easy to get lost or wander around with your fingers crossed, hoping to find your way again. With the iPhone GPS, you can quickly find your location on a map, and get a new set of directions -- or just look at the map and plot your own. If you're adventurous and want to try your own way, you can use your compass to ensure you're always heading the right direction.

The Maps application is the new wave of GPS technology. You'll never have to worry that you might get lost if you're driving with someone else, because you don't have your GPS to rely on. From now on, you'll have GPS on your iPhone, and you can easily find what you need at a moment's notice.

The GPS application is a great way to ensure that you always know where you are, where you are going, and that you can always find an alternate route to have a plan B. With so many useful iPhone applications, it can be tough to decide which are the most relevant and important to have. Luckily, the choice to use the GPS application is an easy one. Once you begin using it, you'll wonder how you ever did without it.
