- Monitor Mirroring Function: The system supports monitor mirroring via HDMI, allowing the high-definition navigation display to be shown on a rear monitor for passenger viewing. When connected to the optional DRV-MN940 drive recorder via HD-TVI, recorded and live camera feeds can also be viewed on rear monitors, enhancing passenger awareness of driving conditions.
- High-Resolution Audio Support: This unit supports high-resolution audio formats including DSD, FLAC, and WAV (up to 192kHz/24bit). This capability delivers transparent and immersive sound reproduction, characteristic of high-fidelity digital audio.
