To replace the coaxial cable for the digital radio, you will have to remove the rear self panel and driver side sail panel. Lower the rear of the headliner to access the satellite radio coax cable, disconnect the electrical connectors, and remove coax cable. In installing, one should install the new coax cable and join the electrical connectors. The next step would be to replace the headliner, the driver's side sail panel, and finally the rear self panel.
