Used to work good for the most part. Now, at random music volume lowers. It appears the volume scale changes, bc you can still increase volume, but max volume is now less than half of what it usually is. It's probably much less than half bc I never get close to cars Max volume, bc it's very loud. The only way this gets fixed is if I change the music app, play a song on app, then switch back to the app I was using previously. Also have to reconnect USB cable after AA starts, Everytime now
