jas32 - is correct! I have a 2015 Note SR and my BT Steaming (Pandora) works perfect.What I'm saying is, you should be able to play any device (iphone, ipod, mp3 player etc.) through your aux input using a 3.5mm aux cable. If this does not work, your radio may be defective. Since you have a 2015 model, I would assume it is under warranty and they should repair or replace the radio.
If there is nothing wrong with your radio you can play Pandora on your smart phone using the cable.
For 2015, the standard radio on the S, S+ and SV models do not have Bluetooth Streaming. The SR and SL models have BT Streaming standard.
