Mine does this (and my daughter has discovered she can have audio of her Mister Maker and Chucklevision videos - on my iPhone - streamed through the car too...). I have the latest Media System 2.1 though. I'm pretty sure the older version and standard stereo won't do it. :(

Works fine with a half decent aux cable though of course! ;)
