fsx navaids/level d airac

I have ordered fsx online and also shortly going to order the level d 767 for fsx.Will the navaids in fsx match up with the airac in the level d 767 for fsx.Would I have to update the fsx navaids and the airac for the level d 767 for fsx?.I would probably prefer not to update it because what I have read on the internet about it,it looks complicated.How up to date are the fsx navaids that come with fsx and the airac that comes with the level d for fsx? and could i fly for example north Atlantic tracks,rnav approaches the way they are without updating them?
