I have a new Garmin GPS 76cx but cannot find any hydrographic maps for my area (Missouri). " The Recreational Lakes with Fishing Hotspots" has been discontinued and no replacement has been announced. Does anyone know of a retailer who might have a CD or chip of this discontinued map? (Central US). I read a rumor (on this forum, I think) that there is one in the works but nothing definite.

Thanks,

Mark
