I recently bought a mazda 6 wagon and I wanted to put in an aux cord so I could listen to other music. I came to find out that the previous owner had already put one in, it was just tucked under the seat. The cord runs out of the bottom of the center console area. However, when I try to use it, nothing happens. Is there a button or something i need to press or is it just broken? The car does have the bose sound sytem. I've tried hitting the tape/md button but that doesnt do anything either. Any help would be appreciated, thank you!
