Hello everyone, I'm new to the forum and a new Android user with the Galaxy S4. I love the phone, and I'm happy to have switched my my iPhone. The only problem is that now my S4 isn't recognized by the USB port in the stock stereo in my 2009 Pontiac G6. Previously, I was able to use my iPhone through the USB port on my stereo and have full control with the stereo over the music on the phone. Now, when I plug my S4 in, it tells me the "accessory is not supported". Can anyone recommend an accessory that will allow me to do what I could previously do with my iPhone? I do have an AUX jack that I can use to play media from my S4, but if it's possible to have control over the media with the stereo and the phone, that would be great. Thanks in advance for the help!
