Hi I've checked all posts but there doesn't seems to be an answer to my problem.
So I've fitted pre 2008 stereo (sony 6cd) to my mondeo 2009 and swapped bt modules, but what should I do to have aux back working? Should I join pins 23 to 19, 6 to 38 and 5 to 39 ?
And somewhere I found that line out left is 37, not 39.
Can someone help me with this, please
You should cut the aux connector wiring and join the connector to 37 (pin1 on aux), 38 (pin4 on aux) and 19 (pin3 on aux). These are the audio in pins of BT/VC module. Pin 5,6,23 is audio out to the head unit.
