If you've already got an Alpine video system, the NVE-N872A navigation system makes the perfect add-on — its accurate, turn-by-turn directions will get you to your destination as quickly as possible.

The package includes a DVD-ROM that's loaded with highly detailed maps of the entire United States and Canada. Just pop the disc in the NVE-N872A's drive, and you're ready to go. Because you never need to access the disc or the drive, you can mount the NVE-N872A conveniently out of the way.

Connect this system to a 2004 or newer Alpine stereo with touchscreen controls, and you'll be able to enter your destination and customize your route simply by tapping the screen in the right spots. You can select your destination by address or intersection, or choose from over nine million points of interest, including restaurants, gas stations, banks, ATMs, hotels, and more.

When you're on the road, the system guides you using a combination of visual maps that appear on your video screen and voice prompts that tell you whenever a turn is coming up. In certain cities, the incredibly detailed maps offer you a simulated 3D view, which show you the physical outlines of buildings and landmarks. You'll also get 3D closeups of interstate and highway junctions, so you'll always stay on the right road.

To enhance your cross-country excursions, you can even access Zagat ratings of food quality, decor, service, and price at the restaurants and hotels in many areas.

With the help of an optional Alpine receiver, you can also subscribe to XM's NavTraffic™ real-time traffic information service. With it, the system can warn you of traffic jams, accidents, construction, and much more along your programmed route. This is especially useful if you have long daily commutes to and from work.

The system also comes with a microphone that lets you input several of your destinations just by speaking their names. You also get a wireless remote for convenient control over the features you'll most commonly use.
