Hi everyone.
Well, I went for my appointment at my Kia dealer today and they do have a Kia Bulletin out on how to fix the clock issue, there's 4 things they try (disconnecting the battery, the reset on the deck, pulling the fuse for 15 minutes and something else I can't remember)...... in my case, nothing helped, still no clock and clock setting screen is still greyed out. So the service manager was totally stumped since this is the first case where the above didn't fix the problem, so he took some pictures of what my Harmon Kardon system was doing or wasn't doing and said he would forward the information to Kia and see if they come up with a fix for my problem. He also said this problem is not limited to Kia vehicles, some Mazda's, Ford's and so on are having the same issue. So it's something that has to do with vehicles with a certain kind of Nav system. I just hope they find a fix for it.
Also, he said the bulletin says this happened on the 17th August, for me, the clock went nutzoids on the 16th, so this may be a totally different bug shrug.
Take care
Regards: Jack
