I'm using an android phone and this is how I set it up. Hdmi cable and USB cable connected to USB port 2. Ran both of those to a samsung mhl adapter. Connect the phone to the radio via Bluetooth, launch pioneer app radio on phone next, then plug mhl adapter into phone. Access to aha,pandora, and other apps accessible. I lose by audio streaming for music files, but the app icon allows me to access them anyway. Making and receiving calls not a problem.
