Hi, I've built a map containing contour data, using line styles 0x21 and 0x22. These are displayed in BaseCamp with the correct elevations. However, if I open a route and try to display the Graph tab, it says, "The current map does not contain any elevation data on the selected route(s)." The route crosses contour lines, so I surmise that the map needs further information. Can anyone tell me what I need to do? Thanks, Mike
