Hi there, I have had a 2013 Punto Evo for a few years now and I would like to know how to fit an aux cable. I have tried buying a cable that plugs into the ISO connection in the back of the stereo and plugs into a phone with a 3.5mm connection. However when I try to cycle through the inputs with the media button it comes up with “No source available” and switches back to the radio input after a few seconds. I do not have the Blue & Me system and I have looked for a usb input in the glovebox and cannot find one so I have no idea if an aux connection would work. Thanks for your help.
