[..] Pioneer Avics2 Portable GPS Navigation System, very impressive performance. -- I have been testing few Navigation Systems in the last few weeks, Pioneer Avics2 Portable Gps Navigation System, has really impressed me with its performance.
This Slim (1.7cm. or 0.7 inches), light Weight (180 Grams or 6.35 ounces) Navigation System is very easy to use whether in the car or out side the car; if like to go hiking, biking or exploring the down town of any city that you are not familiar with.
The Mp3 and the loud speakers give you added enjoyment while hiking or biking, but watch out for the battery.
The maps and other information about the Points of Interest (POI) are very accurate and load almost immediately, and the route updating is almost instantaneously.
The TeleAtlas map database covers the continental United States with Alaska and Hawaii in addition to Canada.
The 3D Map View gives a detailed view of your location and the route ahead, and you can easily zoom in or out.
Full Color TFT 3.5-inch touch screen interface, provides simple operation, in addition, maps and menus are easy-to-read on the large, anti-glare screen.
Pioneer Avics2 Portable Gps Navigation System features also a Night Display option, with Brightness Control of 8 Levels, and a built in Microphone.
This compact GPS unit also features Bluetooth technology for hands-free cell phone operation while driving, which is a great blessing for safety.
The only con in my opinion is the battery life, which is about 4 hours. If you are planning to go hiking or biking for more than 4 hours, you better keep that in mind, but in the car there is no problem, as you can use a car charger which comes with the Pioneer Avics2 Portable Gps Navigation System.
