To use with a headset:
If you have a bluetooth headset, put it in pairing mode and then search for bluetooth devices with your cell phone. When it locates the headset, it will ask you to pair. Hit yes. It will then ask you for the passkey. Most bluetooth headset passkeys are 0000 (default code). Once you are successfully paired, you can use your bluetooth Headset
(A2DP)
I believe you have to purchase the music via Vcast before you can use the a2dp profile to stream music to a bluetooth speaker or stereo headphones. Otherwise there would be a lot of copyright issues if anyone could send mp3s from their computer to their cell phone and so on.
I could go into more details but it would take a while.
