When I first posted I said my maps will work on the HDS units and that is correct. They will also work on the Elite 7 HDI but not the raster maps. The raster maps will only work on the HDS units. My vector maps will work just fine on the Elite 7 HDI . They may make the Elite 7 HDI so they can see the raster but they do have that ability now. Sorry I didn't make that clear. I am not sure they will work on a laptop because the insight planner software to view my maps on the PC may not have GPS capability. Hold everything until I check with Lowrance in the morning.
