The firmware updater should check if your Bluetooth adapter is a D-link.
It is not doing that, and so it can be harmful, as some users have experienced.
The updater does run in my case, using a Sitecom adapter, but even after installing, there is no change at all. Happily mine still works, but I cannot see any headset option whatsoever.
The fact that Apple only supports D-link adapters is a shame.
