OmegaLimit:The visit instructions are not loaded into the GPX file, so it cannot be loaded into your GPS. For geocaching, Groundspeak augmented the GPX file format with some additional information, like logs, placement date, etc. If you open a GPX file with a web browser, you will see all of the XML code inside the file. That augmented information is not in the GPX files from waymarking.com.
I know this is also true for LOC files. I do not know about KML files.
I would really like to see that information added to GPX files from waymarking. It would be more helpful to try to develop an application like GSAK specifically for waymarking. Having the information on a Palm device or GPS would save several headaches. Maybe that feature will be added around the time pocket queries are added to waymarking.com.
Thanks for the info. This is surprising. Since they did away with virtual caches, you would think that Groundspeak would give the same level of support to Waymarking that they do to Geocaching, but I guess not.
