So ever since the iOS 7 upgrade on my iPhone 5 I have been unable to switch between stations on Pandora. When I attempt to switch stations the menu pops up just like it it searching but nothing ever happens. My phone says "Pandora is having trouble communicating with a device," and after that I am unable to control Pandora through the head unit. I have to turn Bluetooth off and then on again on my phone to reset Pandora. Any one else having this issue? Any fixes?
