Yes, I have it set as "automatic". I have even set the pin on my car hands free kit to be "0000", so the same as the default pin of the phone now.
I have just spent 15mins or so playing, and still can't get it to auto connect.
The easiest way to get it to connect (which isn't that easy) is to choose in the car, Info, Phone, Settings, Bluetooth, Register, and then on the phone, choose Bluetooth, Audio Devices, and Select my car entry. It then connects without asking for any pairing code... just a shame it can't work out to do this itself ! I never had any trouble with the razr v3 !
There's gotta be an easier way... I don't want to go back to my razr v3 ! :)
