I am using an iPhone 5. I have noticed that my phone connects 99% of the time when I get in. Only once did I have problems connecting. But once connected, I often get choppy audio when I am streaming audio from the phone. I tried putting the phone directly under the display, because I was trying to hear what the podcasters were saying, and that did help (although it still wasn't perfect). Then at other times the bluetooth audio streaming works well. I also checked to see if it was weak battery, but it wasn't (it still happens when the phone is plugged in charging). What is also unusual is that I could be getting choppy bluetooth audio streaming when listening to music, but then when I get a call, the hands free bluetooth works flawlessly. That makes no sense to me.
