Jaci Posted February 18, 2018 Report Share Posted February 18, 2018 Hi I have an x3 2006 the parking sensors have no sound. When put in reverse the green light on the button comes on. Also radio display is on but won't work. Came on for a while but sounds tinny and crackles. Turned radio off the crackle still coming through speakers. Any advice please Link to comment Share on other sites More sharing options...
