2003 bluetooth upgrade

so i'm looking for a bmw ulf module to do a bluetooth upgrade in my 2003 l322 vogue, now i've seen somewhere only ulf modules with mit-ses on them has the voice activation, now i currently have voice activation on my car, does the l322 have a seperate voice activation module? and do i need to disconnect this to do bluetooth upgrade?

Don't need to disconnect it. The ULF will use the microphone etc. But you do need to get a "mit ses" one if you want to keep voice control.
