If you currently have Sattelite Radio, but also want to add a dvd player to play movies through the nav system, is the only way to get the audio from the dvd player through a FM modulator?

 

I remember reading a post where someone put a switch on the sat input so he could patch in his DVD player; he cut up the sat cable line and tested which ones were the audio lines, and placed a remote switch on it. You could also hardwire in a tape modulator assuming you don't play tapes. If you are pioneering enough, its technically possible to tap into the nav system audio, but don't ask me how to do that
