My Belkin TuneCast is suddenly not working with my iPhone 5. It will charge the phone, but that's it. The TuneCast power light works, but the display doesn't show the station frequency, and it doesn't transmit audio. I was using iOS 7 betas previously with no problems. Today, the date of the iOS 7 release, it's not. I'm using a 30-pin-to-Lightning adapter (for the past year). The TuneCast works fine with an iPhone 4 running iOS 7. Anyone else experience this problem?
