Expandability features permit for numerous upgrades together with DVD, Mp3, I-pod integration, and Bluetooth. The after market units are really well worth the investment. Portable GPS navigation units are presently one type of navigation available in the market. These sorts of GPS units are mainly made to be suctioned to your windshield and powered from your car's DC outlet. The most important feature of these units is their versatility. The device can be easily unplugged to be moved from one vehicle to another.

The Garmin portable GPS systems even use rechargeable batteries, so they are portable and you do not have to worry about finding an outlet to use them.

Others offer other features, such as an iPod player and other audio features.

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.

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.
