Really was not too hard. You need to go in through the back trunk area on the right. Find the screws along the interior that hold the hard plastic interior molds in place. Remove. Remove the little cubby hole on side as well. Open up teh right side interior and teh antenna will be in sight. There are only a couple screws/nuts holding it in inside above wheel well and taking off teh nut on top (where antenna comes out. Slide assembly out through inside. Replace assembly. In and out inside of an hour.
