Hi folks,I recently brought my old Meridian Marine back to life.It died years ago from batterie leakage.Anyway I got a brand new copy of Mapsend Topo 3D and now I need to buy an SD card and reader.I'm not sure what I need though.Size and type of card?A card with or without adapter?Do I need a card reader that can write as well as read etc?I "think" type wise a Micro SD card is what's called for.Beyond that though....?Ideally I'd like a card with enough capacity to transfer at least all or most of NY state on to.Any help much appreciated.
