Send business card

I have a Nokia 6820 and Cingular and want to send a business card to Rosie, my Prius. I have established a BT connection with the car, select a contact name, Details and then Options. I select Send a Business Card via BT. The 6820 asks to disconnect first, and since "No" brings you back to the sending options, I answer "Yes." So it disconnects and says it will look for devices, but, alas, it cannot find anything!

Help would be much appreciated.
