If you do not have Bluetooth, it is a simple install and you can verify easily. You mentioned having a phone cradle, is that something you put in? I have not seen a phone cradle without bluetooth. What I would suggest is to quickly look at how your car is equipped. You can look over these pictures and see where the Bluetooth module is located http://www.bimmernav.com/BMW_X5_Blue...tructions.html

Let us know what you have and we will be happy to help.

One way to test if you have a ULF module would be to press and hold the picture of a face on the steering wheel. If you get a message that says "please turn on the phone" you have bluetooth without any phones paired.
