I'm assuming the car is not prewired. You could use the BT HF puck with Blackberry, you would not need the GSM antenna and antenna compensator in this setup but if the car is lacking cell phone support, you would need a control box, microphone and UHI connector plus the wiring between these (including MOST fibre loop passing the phone controller).
Can be done but it would be costly at the dealer, independent experts might do it at a reasonable cost if you don't want to try DIY.
