FSE BLOOTOOTH Your experiences

Hi guys, I just got my Samsung D500 and now it’s time for Blootooth FSE. Has any of you had any experience with the Audi FSE (micro and speaker Bose) with a retrofit to keep Blootooth -> in Japanese: I want to keep the microphone from the original FSE, where Samsung probably has problems with the impedance. Has one of you retrofitted Bluetooth at his Tel?? Eazy E.
