Ok , this is my first post and a question. I am sure some where in the world wide web there is an answer but.... I am askig here. I just recently purhased a 2004 9-5 arc and it has an auxiliary input cable in the center console. I have no clue how to use it. I tried cycling through all the sources, and double tapping buttons but to no avail. I think it was professionally installed as it is a cleanly routed. I am stumped, please help!
