The Pioneer AVIC Z2 navigation system is a hard drive based navigation system that replaces your car's stereo. Not only does it guide you along to your destination, but you can playback CDs, DVDs, get real-time traffic information, satellite radio and more. However, the really unique feature is that fact that you can put in a CD and have the AVIC Z2 rip the music onto the hard drive! With 10GB of the 30GB hard drive usable for music, you can store plenty of music for your long road trips or your quick jaunts around town.
