I was told by my dealer that there was no Bluetooth intalled in my car altough I had a BMW bluetooth pin card with my paperwork. They advised me to have it installed and wanted 700+ dollar. They also told me that a Blackberry was not compatible with the Bleutooth device and I had to by a different phone (this was in 07).
I played with it a little and I have a bluetooth already installed and after deleting the old phones that the Blackberry works perfectly.
To my knowledge Bluetooth is a universal signal and is competible with any other Bluetooth device. The robbers almost had me.
