With my XM antenna, I mounted the base of the antenna on the rear center of the roof. lift up the weather stripping of the rear hatch and notch the pinch seam so that the antenna wire lays in the notch. Reinforce the antenna wire with elect tape where the wire will contact the notch.Reinstall the weather stripping. Now run the antenna wire between the roof liner and plastic panels along the top of the side window, down the door post, under the pass side plastic rocker panel, and the between the carpet and pass side kick plate (plastic panel near pass feet), under the dash to the head unit. Thats how I ran my antenna wire. There is no need to pull any of the plastic panels off, just tuck the wire in with a DULL butter knife. PS, dont forget to dab a bit of paint where you made the notch. You dont want any rust to start there. The whole job took me 20 min.
