Well, I'm not sure if this is good news or bad news, but my fedex driver dropped off my iphone 5 this morning to my office on his first stop. I chatted with him yesterday 🙂
I updated the iphone 5, synced it to itunes, and walked out to my truck. Surprisingly it is working as designed. There are no problems at all. Bluetooth controls on my steering wheel are working again, I have artist track info, etc on my head unit, and it sounds crystal clear.
The bad news, I have a feeling since the iphone 5 works fine, it will not be fixed as aggressively for those staying with the 4/4s.
I feel bad for you guys and I hope they have a quick resolution for you.
I can tell you with certainty, that my parrot controlled pioneer head unit does not work with the iphone 4 or iphone 4s on iOS6, however the iphone 5 running iOS6 is working flawlessly.
All I can say is, man is this phone fast!!! Track changing is instant, display on head unit is much faster!
