Eureka!

I guess I have managed to integrate the Bluetooth stuff from panucci 0.3.17 into the newest release (panucci 0.9-alpha1)

I know now my mistake from early September. It was to silly. So please, don't ask!

It's working here with a small headset. I'll test it tomorrow again with my car stereo but I'm very confident so far.

I'm not sure if Thomas would agree how I have tinkered the code into his blessed Application. (I'm very unsure with all this GTK and Python stuff - so please forgive me if it's to ugly done - don't forget, I normally use .NET at Windows machines)

How to install?

• Ensure you have already installed panucci 0.9-alpha1 from Extra Devel
  
• Take the 2 *.py files from the ZIP File in the attachment and move them to /opt/panucci/lib/panucci (and overwrite the existing files) - you must have root privileges to overwrite those files!

Thats it. If it isn't anymore working try to start panucci from the command line and watch out for errors.

Please uninstall panucci and reinstall it from extras or extra-devel if you want to revert the modifications.

If you don't know how to follow the install steps above I'm sorry. I don't want to break your device. And I'm afraid that I'm probably unable to help if something gone wrong and your knowledge is to weak. If you're able to follow the upper instructions without problems the whole thing should be very sure.
So please be patient and let test this modification first some skilled and brave people. If everything is working without additional problems and Bugs I will post more detailed instructions. But I want to wait for some positive feedback first.

Edit: Oh, and I still need a good (perfect!) christmas gift for my girlfriend. Perhaps someone could help now me with my problem.
