Wireless GPS Geotagging with D300
Hi, I'm trying to figure out if it is possible to wirelessly geotag my photos. Is there some kind of transmitter that I can attach to my camera that will theoretically work with a Garmin or Magellan handheld unit in my pocket? Sorry for my lack of knowledge on the subject, there are so many accessories to use for geotagging I have no clue what to use.

I'm not aware of a wireless transmitter that will geotag your photos. However, there is an alternative that I use to accomplish the same thing. Since I always have a portable Garmin along with me in the field, I was looking for a way to transfer the gps data from the Garmin to my photos, without having to be cabled to the camera. Furthermore, since I shoot raw, I wanted to be able to write the lat/lon coordinates to the exif data in the nef file. I use a piece of software called RoboGeo to accomplish this, and it works very well. With very little effort, the software will synch the tracklog data in the Garmin to the nef files, comparing the timestamps in both to geotag the photo files. Pretty slick. It's the perfect solution if you already carry a portable gps unit for hiking purposes and really don't want a cable hanging off the camera tethered to a gps unit. It also keeps the 10-pin connector free (which I use for a remote shutter release), and the hotshoe free (which I use for a bubble level).

It works well for me, and it's a fairly inexpensive thing to try and see if it works for you. Here is how I use the product in the context of a workflow:
1. Before heading out on a shoot, synchronize the clock in the D300 to the clock in the Garmin. Not hard to do, only takes a couple of minutes.
2. Carry the Garmin with you on your shoot and have it turned on and in a position to get a good signal. You can use the Garmin for all it's normal purposes during the shoot.
3. After the shoot, download your photo files to a dedicated folder on your hard drive.
4. Download the day's tracklog file from the Garmin to the same folder.
5. Start RoboGeo, and tell it to synch all the files in that folder. RoboGeo compares the time stamps of the photo files to the time stamps of the tracklog points. This establishes the precise location of each capture. This procoess happens nearly in a blink of the eye.
6. From there, many options are available, but I tell RoboGeo to write the lat/lon/elev coordinates to the exif headers of the nef files in the folder. This can takes some time due to the size of the nef files. If you shoot jpegs, it would go quicker due to smaller file sizes. The image data is not altered in any way during this process, only the exif header is altered.
7. My last step is to export the synched data to a gpx file. This allows me to pull up both the tracklog data as well as all of the individual photo data in MapSource. Each photo taken that day shows up as a waypoint, accurately plotted on the MapSource map of your choice. The waypoint names are the same as the file name for the photo. So, if I wanted to see where DSC_1234.nef was taken, I look up that name in the waypoint list and have MapSource center and zoom the map on that waypoint. Now, not only do I have the actual lat/lon coordinates where the shot was taken, but I have those coordinates in the context of a readable map, showing the surroundings of the shot.
8. The exif data is indelibly stamped into the exif data of the nef file or any jpegs that are saved from the nef file to be available long after my memory of the shoot has become unreliable. The same can be said for the MapSource file.
9. At this point, I can then begin my normal editing workflow.

I bought RoboGeo and agree it is very good with a large range of options.
However after discovering the free GeoSetter (http://www.geosetter.de/en/index.html) I find that I use it continuously in preference. Something about the layout and usability for routine GEO-tagging of my NEFs.

The only wireless system I am aware of is Red Hen\'s Blue2Can Receiver which will receive a Blue Tooth link from a GPS and convert the signal to a serial data stream and send the data through the Nikon 10 pin connector. Garmin has the GPS 10 and GPS 10x units that support Blue Tooth and Magellan has the RoadMate series.
Using the Nikon MC-35 and a Garmin GPS with an RS-232 serial port and with the appropriate Garmin data cable one can connect a number of Garmin GPS units to a Nikon 10 pin port and have an additional Nikon 10 pin port on the MC-35.
