I read that the SA644 VO can be enabled and phone paired without the mic and antenna. Since I had already received the OBD cable, I decided to code the VO first while still waiting for the mic and antenna. I had added $644 to the VO and did FA_WRITE to both CAS and NFRM. I also did SG_CODIEREN to the 2RAD (radio professional) module. After the radio restarted, pressing the menu button showed an addtional "TEL" option. But this option is not enabled as it does not have the phone icon instead having 2 dashes in it's place. It looks something like this. http://220.127.116.11/i54.tinypic.com/2zqvhig.jpg

The owner of the photo above was able to resolve this by re-connecting the MOST cable in the distributor block. But his 1 series had SA640 option with no 6FL.
I've not attempted to check the MOST distribution block (I have non-folding rear seats) or the radio connections yet since bluetooth enabling is just supposed to be a plug and play (with coding) for cars factory fitted 6FL option.
If anyone has any idea on what else needs to be done to get the "TEL" option to be enabled please let me know.
I don't have a solution for you, but am curious to know if you have had any luck since posting?
