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.

The majority of the portable GPS navigation devices which are currently accessible for retail purchase do a whole lot more than just helping you get from place to place. They allow for hooking up with DVDs, Mp3s, iPods, and Bluetooth. After-market systems give you excellent value for their cost. They are designed to be attached to the windshield and to receive their power from your automobile's direct current outlet. Their major advantage is how many different things they can do, and you can move them from one car to another quite simply.

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.

Another system for navigation is the in-dash. These units often have touch-screen capabilities. Touch screens make it possible to enter your destination with a finger. Often, you can replace your car radio, in order to gain control of the whole radio system.

With options like Bluetooth, iPod integration, satellite radio, and TV tuners, as well as systems that are designed to fit both standard, and large radios, you can build a system for any vehicle with all the options at a fraction of the cost of dealership installation.

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.
