Auto GPS units (GPS is an acronym for global positioning system), are part of the GPS family, the only completely functional global navigation satellite system (GNSS). Auto GPS units are becoming more and more popular in America and abroad, with many new cars that are automatically coming equipped with them as a key selling feature. Auto GPS units are also known as navigation systems.

Auto GPS units can help tell you how to get to where you are going. More sophisticated auto GPS units can even navigate you around traffic, through unexpectedly closed roads and construction, giving you the next easiest way to get to your destination of choice. In fact, with the touch of a couple of buttons, your auto GPS unit can plan your route to be the shortest by distance, the shortest by time or the most scenic way possible.

As an added bonus, many auto GPS units can help you find everyday stores and places that you need. If you are vacationing in Florida, and while snorkeling you get bit by some nasty and exotic fish, your auto GPS unit can direct you to the nearest hospital, providing you turn by turn directions as you go. In fact, just about all auto GPS units have voice directions (most have a British accent, for some reason that you will probably never figure out) that tell you to turn at certain points in your journey.

In addition to helping you find necessities like hospitals, your auto GPS unit can help you to find lots of fun things to do. If you like going to the movies, but are new to town and do not know where the theatres are, you can have your auto GPS unit hunt one down for you, and then tell you exactly how to get there. The same is true of nail salons, grocery stores, book stores and just about everywhere else. Plus, your auto GPS unit will tell you how to get back home.

With all of these features and benefits, one would expect auto GPS units to cost at least a thousand dollars. While this may be true of the auto GPS unit systems that car dealerships try to sell you, you can usually pick up a separate auto GPS unit at the store for less than $500. In many cases, you can even purchase auto GPS units on sale for just around $300.
