Hey fellas, so I have a problem with the aux input in my 2008 s40, when I connect my phone through the aux input I can't hear anything from the central and pilot speakers, just from the passenger and back speakers, I was trying to get it together but it seems that the input makes a false contact, I tried 4 different aux cords but the problem still.

Does anyone else has this problem &/or has replaced the input? Anythig will help, thank you for your time
