Whenever I plug my iPhone 4 (w/ iOS 5) into the USB port and try to go into the AUX mode of the radio, I get an error message saying that there is no content on the device and that I can disconnect it! Argh! :banghead: The same thing happens if I plug in my old iPod Touch (iOS 4) also. It's driving me crazy that I can't listen to any of my music . Anyone else have this problem?
