this doesn't seem like an upgrade. my car already has the bluetooh hands free system installed and it works fine with all the approved phone models. getting this $575 kit plus another few hundred to see if MAYBE it will work seems like the wrong approach. how can i make 100% sure this will upgrade my current bluetooth? i have premium package/SOS/hands-free bluetooh/navigation system, etc. the whole 9 yards in my car already. not sure if what i'm reading in that package is gonna change anything!?!

and how do i find out which generation is my BMW'S ULF version? the car was sent to dealership around jun/jul 06.
