The AVIC-Z1 is a double-DIN sized, all-in-one navigation system that uses a 30GB hard disk drive (HDD), to deliver information, entertainment, and convenience to drivers. The large-capacity HDD stores the entire Tele Atlas database, including nearly 11 million points of interest (POI) in more than 340 categories. The large 7-inch screen shows a high-resolution map with easy-to-recognize icons, and touch-panel operation permits quick access to navigation functions and audio-visual sources.
