I’ve got a Lowrance Globalmap 3500c and the Navionics Hot Maps premium north chip. With my old eyes I have a hard time seeing the blue contour lines on the white backround. I’ve tried adjusting the contrast and brightness but they don’t help much. Is there a way to change the color of the contour lines or backround color?? My son’s on Millacs right now and he’s having the same problems. I told him to try changing the setting in the map data menu where it says fill in water with white but he says he can’t when using the navionics data.
