I have two units. One is a Lowrance gen 2 no touch, the other elite 9Ti. The exact same map is on both units. The elite 9Ti shows shaded relief over the entire map, but the gen 2 has areas on both ends of the map, pic shows one end, that the shaded relief is missing. Does anyone know why this could be. Is there a solution. I added the pic to explain further. Maybe too much information for Gen 2 to display?
