I have an iPhone 6s with iOS 9.0.2. I have noticed within the past week or so that when I connect my phone to my car charger, the charging light on the adapter goes on and off. First thought was that the adapter had finally died, so I tried a different adapter. Same problem. I tried charging directly from a USB port in the car and received the message "Unsupported device". I tried again with a different cable and still get the same message. So in summary, I have tried multiple charging ports (2 "lighter" style ports with two different adapters), and 2 USBs - 1 is for charging and the other is in the stereo for streaming. In all cases, my 6s is an Unsupported Device. Anyone else have this issue, and what is the solution? I'm getting ready for a road trip and would really like to have my music, as well as keeping my phone charged. Thanks.
