is it maby your phone socket thats got some fluff in it
got a different aux port you can try it with?

Are you charging the phone at the same time?
I had this with my Nexus 6P and the car fast charger I bought for it, once the charger was connected it would drop out the sound and aux in would disappear on the in car menu (2007 Z4M). The only solution is to not plug the power lead in and aux cable at the same time![]()
