After having the unit for a few months now, I thought about a feature I just saw on a Garmin unit and how handy it could be for me in some of my tournament situations.  The Garmin unit displayed the sunset and sunrise info on the GPS screen.  I can find no similar functionality on the 997 or 797 I have on my boat.  Has anyone researched this or cared about it enough to find out if this could be or is available in any of the screens?  I thought it might be in the main GPS diagnostic display, but it is not.
Thanks,
