I did register the phone, I went into the BT-Phone feature, went into the Function Menu, chose register phone, then pressed open connection, on the iPhone went into settings and paired the phone with the 0000 passcode with the headunit, and then the phone pairs and works that time, when I turn off the car it looses its pairing on the headunit side, I will turn the car back on and it will not connect I will have to go into the iPhone choose unpair and then re-pair the connection as the headunit will not reconnect until that is done.
