Everytime i start my car my pioneer avic7200nex radio starts with the radio(which i want) then a few moments later it stops playing music and switches to the usb/ipod source and says its initializing and then after like a minute it says this device is no longer connected. Im not trying to use the usb source and dont even have anything connected to it. Can anyone help? Its annoying because it does this every single time, and it has done this years ago and i fixed it, i dont remember how, as someone told me online and i cant find it anymore. It was fine for a while, and unfortunately started doi
