Pinch, congrats on the new machine. My RK37HC has the heat/ac and bluetooth radio options. To tell you the truth the HST noise is so loud that the radio is pretty much worthless for listening to music or taking phone calls. I did purchase a bluetooth noise reducing headset from Amazon a couple months back that I paired with my cell phone. I can stream music from my phone using my SirusXM app or any other app. With the noise cancellation turn on the difference is like night and day. He headset was roughly $49 and work well. The only thing I regret is not buying a headset with a built in mic for calls through my cell.
