I bought this to replace the existing Aux Jack on my daughters 2011 CX 9. It fit like a glove, but still did not fix my problem. I ended up soldering 2 pins together on the original Aux Jack breadboard and fix it that way. The bread board was a different shape than the original, so I this might not be a direct replacement for 2011.
Fixed my mazda radio not recognizing the AUX input.
Fixed my mazda cx9 2007 radio not recognizing the AUX input. Simple fix by swapping the aux modules. there are 2 clips on top and 2 on the bottom, just pop the unit out unplug then replug into the new one and thats it.
