DOes anyone know if the Aux feature on the Command Head unit can be used for XM Radio input?

Does your radio have an analog audio output? The AUX port should accept audio from any device (levels may be low for some) but my guess is that you are after full control of the XM radio, the aux port does not allow this (for any device).
The back of the radio has an outlet but not a port I am familiar with. Its not regular RCA/Aux port which I am familiar with.
Yes but a set of cables should be available, you are anyway not supposed to connect directly at the back of the Comand. And you probably need to have the car version coded to enable the aux port.
