According to the BT card, it is a Motorola unit, date Sept., 2005. Is this enough info to tell if it is a ULF or BT-assist module?

I tried to pair my wife's phone and it recognized the car but when I tried to pair it with the car I got the message it could pair with the car.

It appears the indication of being paired with my car is constantly displayed on my phone whether it's in range of the car or not. My phone is an iphone, and for the last 3 months since I got the X5 has worked wonderfully.
