Hi,
The factory built-in AUX input in the center console started acting up so I decided to take it apart but can't still figure out which line is used to detect whether an audio jack is inserted or not so that I could change the mode from CD to AUX. There are 4 lines coming from the HU. (Left, Right, Common and Detection line) but I can't seem to figure out how the detection works. It must be that D-Line is closed upon inserting the tip but it is not clear. Has anyone tried to figure out how it works?
