Bluetooth still isn't perfected. The specs specify how to get data from one device to another - they don't specify what the data is or has to look like. So the S3 and the Pioneer may not be compatible as far as phone calls go. See if Pioneer has an update and make sure your S3 is updated. (It could also be that the Pioneer works with the version of Bluetooth in Lollipop but not in KitKat, and you're running KitKat in the S3 - and can't update it to Marshmallow. In that case, there's nothing you can do.)
