Having difficulty as images show up in the middle of the Atlantic Ocean. After looking in the info of the images in Google earth it's apparent no GPS info comes through during the transfer. All GPS data is imbedded in the exif file before downloading to iPhoto. I have been shooting with a Nikon D2x with a Garmin Geko 301 attached through a Redhen adaptor for years and currently have images mapped on Google earth using Panoramio and Smugmug. This is the only software that refuses to identify the GPS data for me.

All images were downloaded to iPhoto without adjustment using Mac OS X 10.4.8 on an intel Xeon Mac Pro.
