It shouldn't be that big a deal... It looks like you just remove all the plastic interior pieces around the sides that hold it up.

The trick is just figuring out all the creative clips and things that Nissan used to tack the interior together with (i.e. you have to know when to remove that secret clip or screw and when you just have to grab ahold and yank).

I do know that once you remove the "oh shit" handle, the A-pillar cover can be just yanked off (I managed to smack myself in the nose with mine when it finally came off ). The thing with the map lights in it also just pulls down (held up by two springy metal pieces)
