How does one control the volume when the HTC Rhyme is in the charging dock station (blue tooth mode? I just purchased an HTC Rhyme and unfortunately at night need to receive calls while the Rhyme is in it's docking station the ring is obnoxiously loud. I have tried volume control on the phone. There is not a control on the docking station. I even tried turning the blue tooth off but it automatically is turned on when you place the phone in the docking station. Any words of advice out there???
