Bluetooth adaptor for Blaupunkt DAB54?
 

When I bought my DAB54, there was a vague promise of an add-on BT
adaptor. iirc, this was for allowing a BT PDA to display track
information, etc.

1) Did this adaptor ever get launched?
2) If so, can it be used as a BT hands-free adaptor for a telephone?
3) If not, are there any suitable addons to allow BT connection of my
handset through this stereo?
4) If not, what do I need for a DAB car radio with BT handsfree
connectivity for telephone + MP3/WMA?

TIA
