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.

There are Garmin portable GPS systems available with built-in batteries to eliminate the need for an external power source. The popular and versatile Garmin Nuvi 350 GPS Navigator's rechargeable lithium-ion battery can last up to 8 hours. It is compact without sacrificing screen size unlike some of the other navigation systems that are available. Moreover, it is not just a navigation system. In addition to providing directions, it also serves as an Mp3 player and audio book player.

Also, you can use a GPS system called the in-dash. This system has an interactive monitor, where you can type in the address to get directions. This unit fits where your car radio goes and replaces it.

No matter what you drive, there are units available to adapt to your radio model. There are all sorts of things available, such as mp3 adapters, satellite radio, television and cell phone options. You can have all of this, and pay way less than the car manufacturer's cost to integrate it into the car.

If more points of interest are loaded into the unit the better the chances of you finding a destination with minimal information. Hard drive maps are actually loaded on your unit; updates are as easy as downloading new maps from your home system and loading them onto your hard drive via SD Card or DVD. Actually maps are loaded onto a DVD which must be inserted into the system. New updated DVDs must be bought as time goes by in order to stay current with the growth of your area.

Now portable navigation systems are affordable no matter what your budget. It's a small price to pay for all the functionality and entertainment and the satisfaction of knowing that you will never again have to pull over and ask for directions.

The addition of portable GPS navigation in your vehicle is relatively inexpensive especially when compared to the overpriced dealership charge that comes when you order a factory navigation system. After market units use the most current technology and maps to help you get where you want to go with the greatest accuracy. Some Garmin portable GPS units have built-in batteries that allow you to navigate without needing an external power source. 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!
