On an 09, I haven't a clue. One way (which is the way I go about doing things) is to start disassembling parts. If the headliner needs to come off, you need to remove anything attached to it and holding it up. (sun visors, grab handles, and possible the pillar trim pieces may be in the way as well. I know on my 04 it was a pretty involved disassembly, good luck.
