I understand your frustration at the display showing Sirius without having the ability to use it. Sirius functionality was an option with Group 301A, which also included MyFord Touch. If you have any additional questions, or need any assistance, please let me know.
To clarify, Sirius was part of different Option Groups on both the SE and the SEL. It was Option Group 203A on the SE and Option Group 301A on the SEL.
