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.

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.

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 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.

There are portable navigation systems priced to fit every budget. Furthermore, the cost is worth the service and entertainment these systems provide. You will never again find yourself lost in a strange city searching for someone to provide you with clear, accurate directions.
