Ok, as it is wet and windy and I can't work on the boat I though it was time to go through some of my last few trips and update waypoints etc, I hadn't used Homeport for a couple of months but when I went to load it, it had an update which had something to do with overlays on tracks, sounded good - however when I used it the first time I could get the graph for Depth on an Active Track with no problems but when I backed out of this and then later tried again the only graphs available to me were "Speed over Ground" and "Course over Ground" which I could overlay but "Depth over Ground" was no longer available. I have rebooted the PC but to no avail, tried to find something on the Garmin site but pretty well bombed out almost as if Homeport was not supported. - forgive me but finally located the site and also posted the question there.
Anyone know how to get my "Depth over Ground" back. I did have a look at the option of restoring a previous version but I think it wipes all my waypoints, routes and tracks in the process.
