I have a 16 GB Ipod touch put a stereo in my car that connects to to it via USB. It has been in there about 10 days and has been working fine. Today it will not work it says, "Can not connect and makes a strange noise!" I plugged another Touch to it and the same problem. I connected an original Ipod to and that will work. Please tell me what to do. I have tried to reset it and it is a Pioneer head unit.
