just an update, I went through everything again, sometimes I can hear the other party sometime not, but the rest is working fine, even ysterday I was able to use the system to make some phone calls withoutany problem.

according to BMW TSB, either the unit needs to be recoded or the connection at the rear of the radion is loose(I could not finf th eproper hex tool size to takt the radio out).

I have an appointment tommorow at the dealership to replace the MFD, also they said that they gonna recode the ULF too, let's wait and see????????
