The Service Manual is your friend:
The component you *do* have there is the Bose amp, what you're missing is the stack of components that does XM Radio, Bluetooth, and Voice Input, which is only there if you have the Bose Audio (Touring?) w/o Nav (bare Cubby). If you have the Nav option, these functions are integrated into the headunit.
Edited: took me a minute to figure out that he has Nav, and that's why those pieces are missing
