I took my BMW to an Offical BMW Dealership and they informed me that I did not have the bluetooth module/computer installed and that I only had the Phone Prep Kit installed.

I went back to Carmax and spoke with a manager onsite about how my Carmax sticker and paperwork stated that the car had Bluetooth Technology built into it.

Without any hesitation they agreed to install the offical BMW bluetooth system into the X3 at no cost to me.
