I have issue with my s9 media connection on my car. The bluetooth connection is ok but whenever i try to play music on my phone through bluetooth connection, the volume control on the car refuse to work, it shows on the car screen that am playing music but there is no sound. I jave read online that lots of people have similar issue. Whereas my iphone connect perfectly alright with my car interm of sound, volume control and playback. I jave tried many times without real solution.
