Problem Solved! No, the wires weren't messed up. I don't know how anyone could do that.
Turns out it was a settings problem. I don't know why, but the Antenna Control has to be in Power mode (vice Radio). XM works, but I forgot to take my iPhone to the car with me, so I'll have to wait until after work to test it. It seemed to work last night (sans audio), so my hopes are high.
Other lessons learned:
Wear gloves in cold weather. My hands are hamburger.
MisFit is awesome. Thanks again.
If you take the center console out, make sure the seatbelt receiver is on the OUTSIDE of it before putt
