Swap Out The XM Antenna For An NMO

Only drop the headliner in the back. Take out two back most screws in the quarter panel trim, remove the sill, remove the D pillar trim, pull down on the headliner. The fin's single nut is within reach with an adustable wrench. Unplug the coax from the sponge wrapped connector and pull up and out.
