@@MrMarkkortekaas I ended up just doing it, it's super simple. The top of the antenna cover just pops off. You can remove the left side tupperware and trace the original xm antenna wire back to the receiver. (It's the pink connector on the receiver) I just cut my original wire at the antennal and fed the new wire through and along the original wire. Something to note is I'd only use a genuine xm antenna, I first tried another brand off of Amazon and it was no better than the original. I then bought the SiriusXM branded antenna and it works perfect. Something else to note is I did remove the windshield before I popped the antenna cover off, that made it a lot easier.
