I had the dealer's service team install the factory Sirius kit, and to my surprise it looks like an aftermarket installation on the antenna? The antenna mount has the wire exposed like an after market installation kit. See pic attached. I think that there is a part number change on the 2011 for the install kit, but I could have sworn the antenna wire is attached like most factory installations where the cable connects to the antenna via the mounting post versus the way it is attached in my installation. Can anyone with a 2011 verify this please?
