you do not need SA620 for voice control. SA620 seems to be for navigation with iDrive.
i retrofitted bluetooth with my MULF 2 HIGH Basis SVS and just added the SA644 (SA664 for US cars) and my voice control worked without adding SA620. this particular MULF2 is for SA620 & SA609 option but it does give voice control for bluetooth phone as well.
the MULF2 i have has a label which looked similiar to this.
