Anyone out there with the factory installed DVD system? There are a bunch of us looking to add to the stock stereo, and knowing how the DVD system is or is not connected would be a great help. First off, does the DVD player only work with the headphones or can you listen to the audio through the sound system? If not, well that is one thing down. If yes, are you willing to take off the center console and tell us what the back of the radio looks like?
