Later, I bought a Nikon GP-1 GPS unit for my D300S. I'll
show both GPS units and cabling in this section. Either of
these GPS units will work with either camera.
Nikon GP-1 GPS unit (see
▪ Nikon GP-1 GPS unit
▪ GP1-CA10 cable (included)
Aftermarket handheld Style GPS unit (e.g., Garmin eTrex
Legend GPS –
▪ A GPS unit that meets the NMEAo 183 data format,
such as the Garmin eTrex Legend.
▪ A data cable for that GPS unit. It must have a D-sub
9-pin connector (not a USB). This is usually included
with the GPS unit. The D-sub 9-pin connector looks like
a 9-pin serial port connector.
▪ The Nikon MC-35 GPS adapter cord (not included with
the camera), which plugs into a D-sub 9-pin connector
on one end and, on the other end, the camera's 10-pin
port (under the larger rubber flap below the camera's
main logo).
In Figure 5-31, let's take a look at the D300S with a Nikon
GP-1 GPS unit attached to the camera's
(Figure 5-31, red arrow). You can also see the included
GP1-CA10 cable plugged into the 10-pin connector on the
camera. I deliberately put the curl in the cable to keep it from
sticking out awkwardly.
One thing to note about the Nikon GP-1 GPS unit is that it
doesn't have a built-in digital compass, so it will not report
Heading information to the camera.
