Corvette's voice-activated GPS navigation system is available as an accessory to guide you to your destination. Features include a CD/MP3 player, as well as AM/FM/XM (if vehicle is equipped with XM) Radio. The user-friendly, LCD touch screen makes address inputs quick. The separate slot for the Navigation disc allows customers to listen to their music CDs/DVDs while using the navigation system. System includes a U.S. map database with major streets and points of interest. This Navigation radio integrates with the Bose sound system and includes AudioPilot® noise compensation technology. The system then automatically and continuously adjusts the music without your having to adjust the controls. The system compensates for speed-related and non-speed-related conditions such as an open top, road traffic or hard driving rain.
