Center console AUX-IN stopped working

[lucardo]

Hello, I have been using the center console AUX-IN with a standard male-male audio cable and setting the input on the radio to front aux. All of a sudden it has stopped working. i´ve tried a different cable eventhough it plays fine on a regular speaker with audio in.

I took the usb/aux-in connector apart yesterday to check it with a multimeter for continuity and the connector seems OK. i cannot use the usb because i dont have the combox.

I want to trace the cable to make sure everything is connected properly but cannot find wiring diagrams or pictures. any idea where i can find that or how i can troubleshoot?

Thank you!
