Was curious about this as well. Today I hooked my ipod into the left and right audio inputs in the rear seat nav, selected "video" with the remote system and could hear the ipod over the wireless headsets. I couldn't however find a way to get the signal to play over the interior speakers as there isn't a video or Aux mode. Is this just the way it is or am I missing something? Why would they make the system so that all of the modes except video can play over the speakers (can only assume that it's because it's intended for attaching things like Play Station and no one thought that the rest of the car would like to listen to someone playing a video game)? Anyone else aware of a simple workaround that I'm missing or is the only solution to open things up and add additional hardware.
Thanks
