Excerpt: The unit connects easily to the V1 and rapidly acquires the satellite signal. GPS data is very, very quick, typically 20-30 seconds for a lock. The only problem I've experienced so far is the inability to connect the unit via the computer to the Nikon website for updates.

Summary: Useful piece of kit, OK it may be a little expensive compared to other GPS units, but then its all down to volume, this only works with Nikon 1 so market is limited.

Summary: I bought this as I was travelling to a remote part of the world and I wanted to know where it was that I had taken the photo's.

Summary: Went to Venice last year and had GPS on camera,it was only when I got home that I saw it's worth. Place names and locations that you missed whilst enjoying the place are recorded so when enjoying the pictures if viewed with the right program's you can see exactly were you took it.
Summary: This unit does what it says. It just doesn't do it as accurately as I would have thought it could: Photographs taken in sequence in the same place show as being up to 100 metres apart on the ground and 40 metres apart in altitude.
