Did you try pugging into the Uconnect box itself? There is an identical "CD changer" jack on the Uconnect box itself, which is located behind the glove compartment. If you bypass the Uconnect (like you are doing by plugging the XM into the radio, and then the Uconnect into the XM pass-thru) then the Uconnect cannot control the audion source. It seems logical that hooked up that way the Uconnect would be trying to talk over the XM. Do me a favor, and try plugging your XM into the Uconnect box. It seems that is how Dodge expects us to run a CD changer. I am interested in the XM Direct kit myself, and I am REALLY interested in you trying it out for me since you already have one!
