Well, I thought that I was having problems with third party shutter release systems (https://www.nikonians.org/forums/dcboard.php?az=show_topic&forum=150&topic_id=251134&mesg_id=251134&page=)
But, I think that I have now diagnosed my problem as a faulty GPS port. I bought a Nikon MC-DC2 to try on my D90. And it does not work at all. I then re-tried my 2 third party cords - and nothing.
Has anyone else had issues with a bad GPS port? I searched on the web, and it seems to be a common problem.
For those that had a problem - how did you get it resolved? Nikon Service Center? Or independent authorized repair shop?
What did it cost? And has it stayed fixed?

I also have a D90 with a faulty GPS port. And, like you searched the net about this failure and agree it seems to be a common problem. I contacted Nikon support as well as the head of customer service. Nikon denies a problem, hiding behind the belief that since Nikon has not published a service bulletin, therefore no common problem exists. Needless to say, I found their response to be shallow. It's like an ostrich putting its head in the sand and pretending danger is not present.
As I understand it, the main circuit board contains the GPS port as an "appendage" and needs to be replaced. The estimates from a well regarded Nikon authorized repair shop and local repair shops are all in the range of $275-$300.
Perhaps Nikon needs to hear from all owners of Nikon cameras that have faulty GPS ports.

I contacted David Dentry. I found his name mentioned on the Nikonians forum when searching for GPS port problems. In my problem summary to his attention, I did include quite a few links to support that the problem originates from faulty design, has been experienced by others, and the problem affects other Nikon camera models in addition to the D90.
Mr. Dentry's response was very disappointing. Will you please let me know if you have better luck?
