That post was over a year ago but unless someones selling it separately somewhere like eBay i don't think you can get the map on its own without the guide, you can see it by doing a quick image search though.

TES games do usually come with a map (and the Anthology with five), but i think this Prima guide book came with a two sided version one like the basic map you usually get and on the other side of it a more detailed map will all the locations marked and named.
