I'm getting tired of doing all these iOS updates and losing control on one or more of my devices. When we updated to iOS 6, my dad lost control of his iPhone through his Pioneer head unit and it would no longer display song info also, he could just connect. Now with iOS 7, I can only connect to the Bluetooth unit on my JVC head unit, but it will not control my phone. Why does apple keep dropping more and more Bluetooth support? Shouldn't they be ADDING more support? What exactly DOES work on iPhone now?
