Does anyone have a picture of where the satellite receiver and wiring should be located? I bought a used 2011 LR4 and would really like to get Satellite Radio installed (without paying an arm and a leg), and if I could do this myself even better.

I had assumed that it was installed prior to purchase because when I select mode SAT is listed, but it was greyed out so I figured I just needed to get a subscription, but I have looked everywhere I can think to find the receiver and have come up empty.
