The base map that comes with the plain legend has more roads than the legend C or the 60 series. The 76 base map and the legend seem to have the same map. I know because I have the Legend and was at Gander Mountain yesterday and compared the Legend C, all the Map60 seriers and the the 3 76 series they had there. The sales guys were surprised to find out that the Legend C and the 60's had less roads.
