Before I posted I was looking at this one from sparkfun,

Can somebody help explain some aspects of the NMEA protocol to me? I was looking in this:
http://www.sparkfun.com/datasheets/G...%20Manual1.pdf
And a few other documents that are similar, it seems as though I just need the GGA protocol. But for some parts in it I don't understand the output. I don't understnad the output of the lat and long values.

Also what values from that string what would I need to to simply tell what the position is?

Here is some background info on NMEA. http://en.wikipedia.org/wiki/NMEA

I would say your could either use a commercial GPS with a screen, etc OR something meant for the hobby hardware guy. You probably want the latter as it would allow you to do exactly what you cant instead of trying to mess with reverse engineering a commercial product (like how there screen works) and it will save you from paying for something that has more features than you need.
