Whatever kind of auto you have, a portable GPS navigation system is a cheap way to enhance it. These devices have the latest in technology that will help you find your way without getting lost. And since there are improvements made all the time, a portable GPS navigation system is a lot less expensive than paying for one that comes with the auto upon purchase.

Many are not aware that portable GPS navigations can be used for a number of different purposes, and getting directions is just one. Most are upgradable to be used in conjunction with DVD and MP3 players as well as with Bluetooth capability. Even the after market units can be a great investment. These portable navigation systems that are available are easily installed with a suction cup attached to the windshield. They also use the battery of the car through the DC outlet. These devices are very versatile and can be easily transferred from one vehicle to another.

Some Garmin portable GPS units have built-in batteries that allow you to navigate without needing an external power source. The Garmin Nuvi 350 GPS Navigator is very adaptable and includes a lithium-ion battery that you can recharge and it will remain charged for up to 8 hours. It is small enough to fit in a purse or a pocket, yet it has a large screen. The Garmin Nuvi 350 Personal Travel Assistant gives you more than just directions; for starters its features include an Mp3 player and an audio book player!

There is another type of navigation system called the in-dash. In-Dash Navigation units generally include a touch-screen monitor, which lets you enter destination addresses with your finger-tip. These systems can replace your factory radio, and provide control over your entire audio system.

Now that these devices are made to replace both regular and large radios, you can locate a GPS for any car. Even adding such extras as Bluetooth, iPod hookup, satellite radio and television tuners still allows you to upgrade your automobile at much less than what a dealer's bill would come to.

If you put as much information into the GPS system as possible, it will be easier to find your location. Some maps are on the hard drive of the system, and you can just download the updated ones and put them onto the hard drive as updates. There are also actual maps, which are on a DVD the system can read. So you will have to purchase the new DVD maps so that you can stay up-to-date on new roads.

While they were once expensive, portable navigation systems have become affordable for everyone. Money spent on these systems is more than worth it when you consider all of the utility and fun that you get for the price. Most importantly, however, you will never have to stop for directions again with one of these systems.
