This game is soooo frustrating! It goes from nauseating "My wife says the kids are just like chipmunks - chip off the old block" to some really great & well thought out features.
On to the problem - anyone have a problem of starting a saved game and not having your sub show up on the map? Everything else works but I can see my position of the nav map.
EDIT:

Had the mod real navigation installed - D'Oh.
