What's the process to do this? Does the headliner have to come down to get these antenna's out?
Yeah, it does. Remove the 4 screws from the sunvisors, 1 screw from the upper control pod assembly and pop it down, pop off the A-pillar plastic, remove rubber around the sunroof, and pop out the clips from the passenger side handle. Headliner should drop down enough to get a wrench in there. It was a 10mm for the Onstar on the drivers side, and a 22mm for the XM.
