That was a suprise to me and the dealership! I ordered my mini with the premium package, which came with cruise, and radio controls on the steering wheel...that is all I thought I woudl have...but to my suprise...there the bluetooth was! Don't know exactly how it works but dealer dudes told me it was integrated through the stereo....we will soon see...
Now if I could only get a phone from sprint that is decently priced which has bluetooth! They are putting one out here in the next couple months that should fit the bill.
