Eeesh, stereo stuff isn't my area of expertise, I'm more mechanical, like engine, transmission, ECU recalibration. I had a friend that worked at best buy a couple years ago and I remember him saying that the Pioneer AppRadio worked well with some devices and refused to work with others. I know he had to have customers download a special app on their phone so it could communicate with the head unit. Other than that I'm just pissing in the dark here. Just as confused as anyone else would be.
