I found that I am able to play my Samsung Galaxy S4 music streaming through the blue tooth of my car only if I have the Samsung music ON FIRST on the phone BEFORE I START the car. Try that. Good luck.
yes, have the music plying on the phone BEFORE you start the car. It usually works in my car, but not always. my car is a Lexus and the service people could not fix the problem because there is NO solution. Good luck. Armand

I have the same problem but what I do is having the Samsung music playing on the phone BEFORE I start my car. Due to that problem, I am thinking in switching back to iPhone. Good luck
