I went to PC111 web--site to see if they have updated any maps for my bike, there weren't any. When i look at different threads i see people that have done there own mapping. My question is, how does a person do there own maps and how do you do it. By doing your own mapping what are the pro's and con's on doing it. Is it hard to do it? How hard is it to do, and what are you actually doing when you do your own map?
