Just upgraded to the iPhone 6 yesterday. My iPhone 5 worked fine with my usb plug in on my 2011 Honda Civic coup EX. Now all the sudden it won't play anything from iTunes. Any ideas as to why? And Yes, my iPhone 5 had IOS 8.
Honda and Toyota OEM sound equipment is from hell, insanely bug ridden. I doubt much can be done, but if you report your problem to Apple maybe if they have time they'll try to come up with a workaround for Honda's screw up.
