I placed a 2007 version hot maps premium chart in my Lowrance and no details or contours are showing. I followed the directions and the chart is compatiable with my Lowrance. Anyone have similar issues and if so, how did you resolve your problem?
When you select the maps under menu,go to the navonics map and select Lowrance and look through the list to find your map. In my case I selected SMI for southern michigan to get the Detroit River. If you don't select a map under Lowrance (assuming you have a Lowrance), nothing will appear. If you have other problems let me know I might be able to help since I think I understand the map feature now.
