Is this normal or is this a problem. When I try to plug in a video game system, or a camcorder, into the video and audio inputs in rear navigation, I can only get audio through my headset. I want the audio to play through the car speakers, b/c sometimes more than 2 people want to hear whats going on.

The dealer said, it's not possible, thats how it is. But I don't believe it. Does anyone else have this problem.
