cdavie2002 Posted May 13, 2020 Report Share Posted May 13, 2020 I have a 2003 M Sport. I recently changed out the Factory Head Unit (Business) for an XTRONS Unit. I cannot get the sound to work. See attached pics. This is the original Loom. Some cables that weren't in use previously. This is the Android Junction Box. These are the wires that have no obvious connector, for me anyway. Android Wiring Diagram. As stated, no sound is the issue I have. Any/all help would be greatly appreciated. Chris Link to comment Share on other sites More sharing options...
