For some reason, I cannot access the GPX file. I followed all of the steps of the tutorial, but the folder C:\ProgramFiles\gsak\garminpoi is never there. I have looked all over for the GPX file and it is shown as being exported to my "User" folder, but when I open that folder it is not there either. Could it be that I need a firmware update for my Nuvi? I did not think that was the challenge as I have not even gotten to the point where I can upload to the Nuvi anyway. Any help would be greatly appreciated.
