Navionics data overlay.....Lost???

[Pelagic 660]

This is a bit of a stupid one.....has anyone lost all of the data/info that normally shows up over the map? I was mucking about trying to delete an old route and save some new ones when the unit HDS10 went to the loading screen and when it came back to life all the info was gone. Waypoints and routes still showing but info like contours, marker beakons, green zones etc are all gone......what have I done??? is this me being dumb or have I deleted something I shouldn't have.

Any help would be great. Trev

My unit must have been confused, turned it off, went in for dinner and a bit of time surfing ausfish and youhoo tube back out to have another look, turned it on and all good. all the info was back on the screen.....I guess it just needed a break.
