I have an older HDS5 Gen 2 Lake insight. I never did have a gps map card for it, but wondering which one I should get.
I’ve seen some stuff online about these Genesis maps, or C maps or something? Or should I just buy the regular old Navionics card? There seem to be too many damn options out there now, i’m sure i’ll order something that turns out to not be compatible because why wouldn’t I?
