On my 6-disc factory head unit, there is an AUX button. If you wanted to hook something into the AUX controls, how would you go about that. Has anyone pulled the radio out of the dash to check what the plugs look like?

 

When you find out about the AUX button, let me know. I'm thinking about adding an XM Radio and was wondering if that would work with the AUX.

 

Factory Radio's ARE NOT satellite ready, either have to change out the head unit or use an FM converter.

At this time the AUX button is not supported.... this is per manual that comes with Truck.
