Ok, so being a technical dullard, my chart subscription has run out. I've renewed no problem, bought a new SD card to put the info on. Ive down loaded the new charts to my active captain app and transferred the data (I think), but I've now lost all my fishing marks and relief shading from the app and plotter. Marks are not really an issue as I know where they are physically. But not having the relief shading is pissing me off. I'm sure this happened last year but I can't remember what I had to do to sort the issue. Any ideas??
Im fed up sat here for an hour trying to work through the settings and getting nowhere.
