Navigation

Im making a first person shooter and am trying to make a navigation screen that allows you to see where you are relative to the level you are on - this is proving a little tedious. Any ideas?

ps I have the game ‘epolice’ from ‘The official gameblender kit’ CD. This has a navigation system but i can’t see how they rigged it up. :frowning:
