Do you actually really mean no libraries at all ?

If so why ?

If you want to learn how to manually interface with a NEO-6 GPS, I suggest taking a look at how this library works. I wrote it in a really easy to understand manner, so studying the library's .cpp should give you an idea on how to do it on your own.
