Sirius radio help

[m3buzz]

I have searched this forum, and google more generally, to try to determine where the satellite radio module would be located in my 2011 X5d (build 10/26/10). I found pics of the module in 2009's and some info on E53's, but my trunk space does not look like either of those, and in the rear left compartment, I don't have any 'spare' fiber or wiring.

I did a VIN decode, and I do have $693 option for sat radio prep, so I was assuming that there would be some unconnected wires/fiber somewhere around there, but I can't find anything. Has anyone encountered this?
