Actual Physical Location Of The XM Antenna

[rjmoose]

I searched on this forum and AVIC-411 and surprisingly did not find a clear/complete answer:

Where is the XM Antenna located on the H3? Is it that Short, Black, Rubbery Antenna on the top of the roof or is that just for OnStar?

Someone else mentioned that it was on the top of the roof and looked like a "Hockey Puck", but I don't have anything like that on my roof....maybe it's somewhere else?

Thanks in advance. I always appreciate everyone's expertise on this forum.
