The N810 is the first device I ever owned that had a GPS. The geek in me couldn't wait to learn 1st hand what I could do with a GPS. I felt there was a real need for a task oriented HowTo and there's no better way to learn than to teach. http://fragostech.com/MaemoMapper/
is the result of that effort. I will be updating the HowTo as Maemo Mapper has new releases and when I find more questions about GPS that need answering. I welcome comments from user community and the opportunity to make this an even more useful document.
