My car has both an iPod jack (USB) and bluetooth for pairing. Once it is plugged in or paired, I can change songs via steering wheel controls. Periodically, I hit the next button and it doesn't switch songs. It updates the information on my screen in the car, but doesn't actually advance the song. I have to reboot my iPhone to fix it. I recently switched back to an iPhone, so I don't know if this is an iOS 8 bug or if this bug has been around for awhile. Anyone else having this problem?
