Hi, I have a 2013 Subaru Outback, and I've had this problem for a while now. Whenever I connect my phone to the radio via USB, my music starts playing for a fraction of a second, then fades out, as if something else was about to start playing. It says it's still playing on my phone, and when I unplug my phone from the USB I can hear it continue playing out of my phone speakers, but even at max volume on my radio (40), no sound comes out. I've tried using multiple apps (Music, YouTube, Tubex, etc), and nothing will work. Please help! I have an iPhone 6!
