Having a GPS system in your car can reduce your gas use-sage. How? By continually giving the most direct routes to whichever destination you need to go. If it's raining hard and visibility is lower than usual, a GPS can serve as a navigation partner to help you find your way home or to wherever you want to go. This saves you time and gas from spinning your wheels, potentially getting lost along the way, and giving yourself a migraine in the process.

Not only does a GPS give you the most accurate directions, it also provides for projections as to how it will take to get to a certain objective by a particular path. You can then compare paths and time predictions. When you take all of this into consideration, you will realize that paying a few hundred for a brand new GPS unit is not much considering how much it will save you over a short period of time.

Here is a small example. Let's say it costs you $30 each time you go fill up your tank. Imagine that before buying your GPS system you had to get you tank filled on average once a week. That's $1,520 for an entire year.

Now, let's pretend you got you GPS unit up and rolling. With improved efficiency in getting to your destinations, you effectively have reduced the amount of wasted gas as a result of not getting sidetracked or getting lost while driving. Possibly you will only have to get your tank filled up once every two weeks instead- in which case you will only be spending $760 a year for fuel. A savings of 50%.

This is just one example. However, you can see how you can get a return on your investment over and over again simply by purchasing a GPS system which ranges anywhere from $100 or so to $1000 or more. But you don't need to get the fanciest model right out of the starting gate. Anything within the $200-$400 range should give you a very tough system in general.
