Where can I find firmware updates for Nikon and how do I install them?

I've been seeing for a while that there are firmware updates for cameras. In my current case I have a Nikon D90. Where can I find firmware updates and how do I update them?

Thanks for any help.

Answer

Nikon Support Site lists all the firmware for their cameras. Download v1.0.2 for the D90 using that link.

I believe the steps are as follows:

1. Unzip the file


2. Run the setup routine and follow the instructions


3. When finished navigate to your desktop


4. Locate the Nikon folder


5. Inside this folder copy the NKLD01002.BIN file to the root of the memory card


6. Turn on camera and go to the menu


7. Go to the setup menu (the wrench looking symbol)



8. Select Update


9. Confirm firmware upgrade (e: 1.000 -> 1.002)


10. Click Yes


11. DO NOT TOUCH THE CAMERA while the firmware updates.


12. Message appears saying firmware updated and that camera needs to be turned off


13. Turn camera off


14. Turn camera on and navigate to the firmware menu option


15. Ensure version number is now the new version (ie: 1.002)

NOTE: I have already upgraded mine, so you may actually be prompted at step 3.
