Looking at getting the Commander and just wondering it say it fits the models listed but does anyone know if it would fit an Armada?

Were you able to get the Commander installed? If so how? I just bought an Armada and I too am looking to install XM. I have the Commander from another vehicle but I am unable to connect the FM modulator to the head unit. I cannot locate the antenna plug for the FM modulator. I am stuck. I don't really want to cough up $400 for the XM antenna and I really like the size of the Commander.
