dumb google maps question please enlighten me

[Jokeurmnd]

So first of I heard from a guy a work that google maps is great so I got it and i enjoy it but it seems that when I read post about gps here that you guys are referring to actual "located" then drawn a route deal. Now I've only used GMaps to find stores near by. Am I missing the fact that it can let me know where I am even though i don't? Also give me a way to a bar near where I'm lost at? please correct me if I'm wrong and if not please let me know how to do these cool things. Thanks a bunch you guys.
