Yes, that is what I'm saying....

I spoke with a member who has done this, and he sent me a few photos, so I'll post them here for everyone.

I am going to remove the rear C-pillar, to determine which frequency I have, then replace the old antenna with the new one. The new antenna uses a single cable instead of both, so the currently unplugged second cable will just go unused...

BTW, I think that the cell phone antenna goes through here as well--when I ran a direct cable from the antenna to the center console, I got no reception.. when I used the existing coax cable, the signal went up... It must go through here...

Old antenna vs. new one:
