NTG3 uses an in-dash DVD (and CD) changer and CompactFlash reader for MP3 music. A digital TV tuner and a Harman Kardon Logic7 stereo sound system with 14 speakers and a 600W 13-channel DSP amplifier can be optionally installed and controlled via COMAND. Where a factory fitted rear seat entertainment package is installed, this can use the NTG3 digital TV tuner and the surround sound system for playing out its audio over the speakers instead of headphones. As with previous models, Linguatronic voice command and control is available as an option too.
