I recently installed a new car stereo, which has a USB connection to android devices, which allows you to control the music (play, pause, skip track, etc) from the stereo panel to avoid having to use your phone while driving.
When I try and use this with my Fairphone 3 however, I can use the controls, but the sound still comes out of the phone speakers, rather than my cars.
Does anyone have any ideas why this might be happening and how I could fix it??
