Just wanted to tell everyone I "solved" the problem of the official Samsung Car Dock not playing music and phone calls through the headset.
Well, sort of. I removed the entire "USB slider" mechanism, and just hook up the power cord and headset directly to the phone.
If you pry apart the back of the slider, there a just some small screws holding to the dock. It comes apart easily.
Not quite the software solution I would have wanted, but the official dock is pretty cheap right now compared to alternatives, so I went with it.
