My wife and I have yet to receive the OTA update for our DXes. I verified my system version is still .516. Every time I hit "System Updates" it either gives me a quick "can't do that right now" message or it sits and spins forever on "checking for available update". I have not received any notifications of an update being available. Is it just my household? Is anyone else experiencing this? And does anyone have advice for me, besides "be patient"?
