Question: Sony SRS-BT100 with Mac OS

I use a Mac 10.4.11 , & with bluetooth setup assistant have paired my Sony SRS-BT100 speaker. However when I click on this in Bluetooth Preferences / Devices, it comes up paired - Yes , this device doesn't have necessary services. Connected - No. In System preferences / Sound there are internal speakers but this SRS-BT100 speaker doesn't appear nor does it appear in itunes. Software update tells me that for this OS I have the latest software. Am I missing a minor setting or something which can rectify this so I can stream music from Itunes through this speaker? Will much appreciate any possible assistance :}
