Ok, so, I just recently purchased a 2007 Mazda 3, and I am unable to get the media button for the AUX input to work. I've read on multiple sites that the sirius adapter is plugged into this port, but nothing tells me how to reverse that. Is it possible to simply unplug the sirius adapter and use the AUX input again? I don't plan on using sirius, ever, but I'd like to be able to use the AUX port. Any help on this would be much appreciated.
