Can't use iPhone on JVC car stereo since iOS7.
Prior to the OS update I had zero problems using my 4S in my car for music. Since the update it's completely unusable. The second I plug the phone into the USB cord it automatically starts playing Pandora--which is annoying in and of itself--even though the Pandora app will NOT be open. I check background running programs and make sure it's not open and yet it's still playing Pandora automatically. That's the first problem, because I can't exit Pandora...because it's not open in the first place. I unplug my phone to open and then close Pandora so I can listen to the music stored on the phone itself. Now, I can play that music fine, however the stereo display flashes PAUSE or CHK DEVICE instead of the track/artist. To make matters worse, if I try to change the volume of the music, the stereo volume immediately goes to 0 and only alternates between 0 and 1 so I can't hear anything, and sometimes randomly the volume starts working again but it's playing PANDORA AGAIN, and not the music I was listening to on the phone.
I tried the stereo with my wife's iPhone, also 4S but without the new OS update, and it works totally fine without any of the issues I'm having. I tried resetting the stereo but all it did was make it worse and now it's scrolling some in-store display on what the stereo is capable of which just makes this even more frustrating than it already is. This stereo is only a few months old, and I don't want to spend the money on the 5S if it's not going to perform one of the primary functions I purchased an iPhone for in the first place. Please fix this problem.
Stereo Model: JVC KD-R540
