Again, there is no prewiring for Sirius or HD Radio in LCIs. If you pull your head unit out, you'll likely see the Sirius dog and/or the HD logo on the labels. If for instance, yours don't have the Sirius dog on it, then you would need to replace your headunit for another LCI's head unit with the dog on it (and then have it programmed).
But forget about pre-wiring, shark antennas and all of that, that is only for pre-LCIs. None of that works on your 20011.
