I’m pulling GPX files directly off a Garmin eTrex 30. My camera’s (Nikon D610) clock is perfectly in sync with my GPS. I’m importing the GPX track into Aperture. It shows up correctly, and the I drag a photo onto the track and assign the photos from the project based on the track. The photos do not get tagged correctly. Maybe 10% of the photos show up accurately, but the rest are all over the place. I don’t know where to start troubleshooting this. Any help? If you need more data from me, please let me know. I’m happy to provide my GPX and NEF files.
