Hello everyone,

I have a 2009 Mazda 6. My radio is giving me the error code "Com Er" when I press the AUX button. It will say that then go back to the normal radio stations. Can anyone give me any advice on how to fix this?

Thank you,

Thea

 

What is mentioned in your owner's manual? Anything?

Are you pressing the AUX button while a cable is plugged in? or Unplugged? Can you test another cable and another device?
