Hey guys,
I thought the AUX input was for the plugs inside the center console. They seem like they're AUX video/audio inputs in case you want to plug in your PS3 or XBOX 360. I will post pictures once I take the pics with my phone. I have an FX50 with tech package, and it's in the center console, where you put in the DVD.
I'm just not sure if all models have it, I know mine does.....
