BB Curve :: No Stereo Music From 8310 To Motorokr S9?

I have had my ATT BB 8310 for almost a year and recently bought a Motorokr S9 Bluetooth Stereo Headset to use at the gym. (tired of getting tied-up in the wire!) Anyway, I successfully paired the S9 and everything works (Phone audio, music controls, etc.) except the music still comes out of the BB! I called Moto and they said it should work (I have 4.5.0.182 in the BB). When I power-up the S9, I get a connection message on the BB saying Successfully Connected and green checks for Hands-Free, Stereo Audio, and A/V Remote Control. But the music still plays out of the BB, not the S9.
