As well as being an in-dash GPS device, the AVIC-Z1 is a formidable multimedia player. It can play MP3 and WMA discs, has an integrated 30GB hard drive for ripping a digital audio library, and can be used to control iPods. With the car's parking brake engaged, the Z1 can play DVD video on its 7-inch display. The system also has RCA connections for a rear-video display and external media players.
