Start from doc/doc.md and you can easily navitage through the documentation
Garmin eTrex 20 are shipped with the feature of create/edit profiles. You can do it "graphically" directly from the device, but in the end every choice related to a profile is saved into an XML file with a .gpf format. The aim of this project is to document every field inside these files (since I found no documentation about it online)
- doc folder contains all the documentation written about .gpf files and it's the core of the project.
- shipped-profiles folder contains all the .gpf files that were shipped with the eTrex 20x
- custom-profiles folder contains all the .gpf files created for experimentation
All the testing has been done on a Garmin eTrex 20. I don't really know if the same settings are applicable to other Garmin devices
