I have earlier used a stand alone GPS, software and a computer to merge GPS data into image EXIF files. I had high hopes that this Nikon GPS would simplify the process, which it did. However, what I did not anticipate is the discontinuity with which the GP-1A operates. To save camera battery the GP-1A shuts off soon after each exposure. You now have to press the camera shutter release half way to wake it up again. It often takes many seconds before the GP-1A makes sattelite contact again and the GP-1A indicator light turns green. Meanwhile you either wait or you take a picture without GPS information. The GP-1A is not smart enough to remember the last location and use it if you decide not to wait for new information.
I have been using this GPS unit with my D7100 for about 2 weeks now, and I like it. It does notably decrease the battery life but not so much that I have had to start carrying an extra battery. I have been re-training myself not to turn the camera off. The GPS goes into a slow update cycle when the camera is on but in sleep mode. So when you wake the camera by touching the shutter release or whatever, the GPS finds a lock much faster than it does from power off. I still run out of energy before the camera does.
I use this unit on my D7100 mounted on the hotshoe. The cable attaches to a side port. It sometimes takes a few seconds (up to about 30, depending on conditions) to acquire a satellite lock but once it does I've found it to be extremely accurate. Surprisingly it seems to have no issues acquiring a lock indoors in my home (single level). GPS should come internal to the camera but the fact that it doesn't isn't a fault of this unit, it functions as designed. I've mounted it on the camera strap before and it worked well there, too. The cable is stiff and doesn't flop around. Give this unit decent care as you do your multi-thousand dollar camera and lenses and it should serve you well.
