Andystandin Posted February 16, 2020 Report Share Posted February 16, 2020 (edited) Hi i hope someone can help me. I’ve bought the aux cable and plugged it into the back of my business head unit and aux does come up on the screen but as soon as I plug an iPhone in the aux sign goes off and I can’t play music. Is it possible to put the cable in upside down in the back of the head unit. It’s in a 2006 e46 I hope someone can help. Thanks.
