Pairing Motorola DC800 Bluetooth Stereo Gateway

Please help!!!

I have (unsuccessfully) been trying to pair up the Motorola DC800 Bluetooth Stereo Gateway to my iMac G5 so I can play iTunes through my stereo and keep getting "There were no supported services for your device". I thought it would pair like a headset and appear in sound settings under system preferences but nothing appears and i get no sound output... please help...

iMac G5 Mac OS X (10.4.5)
