I have a usa 6 model, 2 months old. The volume dial does not work, it just spins freely which is a real PITA. I called the hotline, and had to leave a message with no response yet. With all the car shows starting, I really don't want to remove this thing and send it to California for repair. An suggestions or has anyone had a similar problem. I know i'm grasping at straws, with the most likely answer "pull the radio and send it back" I'm hoping for an easier / quicker solution. Thanks!!
