Garmin Auto Gps Units

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.

Auto GPS units are probably the coolest things to hit the car since the cup holder. They can direct you anywhere you need to go, navigate you around traffic, construction and unexpected road blocks, help you find a nail salon and do it all with style. The voices on auto GPS units are almost always British and female, which go a long way in helping you to feel a bit closer to your inner James Bond (even if you are in a 1992 Ford Taurus).

These days, auto GPS units are available as an option in just about every new car, keeping more and more people from getting lost each day. One of the coolest things about auto GPS units is that auto GPS unit users do not have to subscribe to an additional service, costing extra money, for the devices to work. Other car gadgets, like OnStar, require you to spend extra cash each month just to have the thing work, kind of like a cell phone. With auto GPS units, on the other hand, you just plug it in to make it work and get to your destination.

Still, despite the fact that auto GPS units are prevalent in America today, few people actually know how they actually work (even if most of them use GPS on a day to day basis). To clear up any confusion, here is a glimpse on how auto GPS units work:

Each auto GPS unit has a receiver that calculates the position of your car by timing the signals that are sent by the mass of GPS satellites way above the earth. Each satellite continually sends out messages containing information, which is then picked up by the receiver, which is then sent through the auto GPS unit for it to compute the exact position of the car, a calculation made using geometry and trigonometry.

This information is then mixed with the data that came with the auto GPS unit when you bought it, giving you a map with a you are here dot that moves along as you do. The result is the map on the screen of the auto GPS unit that tells you which intersection you are at, which direction you need to steer to get where you are going and how far away your destination is. All in all, auto GPS units are one of the most useful technological advancements in the last few years.
