Sounds familiar (see this post).

If the '06 is anywhere similar to my99 removal of the tail light assembly is fairly simple. Open the trunk and look behind where the taillight assembly is. Probably will have to remove a trim/cover piece and then you should see that there are several nuts holding the taillight system in place. After removing all the nuts, and disconnecting the part with the bulbs, the whole thing should just slide out...
