2011 Mazda3 Sport Aux not working

Hello all,
I recently purchased a used 2011 Mazda3 Sport from a dealership and went to use the aux to find that when pressing the button on the console, it does not respond. I tried the mode button on the steering wheel which yielded no results. I was wondering if it could be the aux input or something may have failed in the stereo. The cable I used does work and have tried it on other cars. Any possible solutions/suggestions would help!
The aux button is also the same for bluetooth audio. Is your phone connected by Bluetooth at the same time ? If yes and if you see a little music note icon on the car display then the aux mode is waiting for music through Bluetooth.
