AFAIK thereis no digital audio. Even if there were I doubt it would be of much use - the AM/FM radio is analogue (the audio from the SAT radio is connected via the CD changer input, which is analogue) - so the only audio within the RNS-E in digital form is the navigation instructions and the MP3 from the SD cards and the DVD player (which will normally have the navigation DVD loaded). So a digital audio output will be of very limited functionality.ATB said:okay...no problem. To clarify, I am refering to a digital out for the audio signal, not the video. Understandable that no one wants to break open their $$$ unit.
does anyone know the oem for the unit? (alpine, panisonic and blau have been popular)
