Has anyone married the D7K with any of the smartphones that have GPS/AGPS capability. I'm looking at the new AT&T HTC Inspire. It has a mini usb jack. With the right cable could u hook the phone to the 7000 and record the lat/lon info into the xif info. I don't need a full time GPS and thought that for those times that I might, this would be a great solution. Has anyone seen a solution or APP that may work.

The Nikon GP-1 does not connect to the camera through the USB port, but uses the camera's accessory port.
Since the GPS-1 also connects to the D200/300 series with an optional cable change, I would expect the accessory port of the D7000 and GPS data encoding method and transmission requirements are the same as what is required by the D200/300. The GPS data is transferred to the camera once a minute.
The D200/300 uses the older RS-232 serial port with no handshaking at 4800 baud. The data stream must conform to version 2.01 or 3.01 of the National Marine Electronics Association NMEA0183 data format. The D200/300 GPS connection is through the 10 pin accessory port on the camera and this port supports an RS-232 serial data port and the remote release interface. There is a separate USB port on the D200/300 for the computer connection. This appears to be how the D7000 is also configured, except that the D7000 uses a different plug and socket format than the D200/300 does. Note that the RS-232 serial port is a very different type of communication port the the USB, Universal Serial Bus. The RS-232 port only supports one device at a time and is much slower than the USB port, which can support multiple devices at once.
The USB port on the Nikon GP-1 is for connection to a computer and when the device is connected to a computer, there is no data transferred to the camera.

I donot believe these smart phones can work on the D7000 or D300. Since the baud rate are not the same. The camera is 4800 in baud rates while the smart phones are much more higher than that. So even the cable is right, the camera can still not get the data. And second, the cable are special, not just the RS232 or usb port to GPS can meet the needs. So what I recommend is to buy a direct gps device to work for it. Many gps devices can do that. GP-1, Solmeta, Easytagger, Dawntech. What I prefer is a Easytagger one, simple to use, powerful and cheap. And the second choice is a bluetooth solution, but also needs a main device and a receiver. Something complicated than the direct connection.
