I have one about 3 years old. All of Canada. Was in an HDS7 gen 1. I now have a Plus card so I can load local area, but allows Vancouver Island. Old card is surplus. Coming to the Island near end of June. Do not really know what the value is. Could mail the card. I think this is the one that requires a Navionics reader to put it in a computer. Will look for the card. Put it safely away, so it is presently safe from me.
