Nikon GP-1 GPS Unit- D90 Only? No! D3, D700, D2x/s, D2hs, D200!
I can’t find any details on the GP-1 and or that says that the GP-1 can be used on anything but the D90. If anyone sees any material like that, please let me know.
I’m sure there’re plenty of people who’d like to use it on their D3 and D700, etc.
[Update]
I was able to find some official info here.

From the product website:
It’s compatible with: D3, D300, D700, D2X, D2Hs, D2Xs and D200 (via 10-pin remote terminal cable GP1-CA10)
