I installed the NC Topo map and, after first installling My Trails, was successfully able to see the option for NCTopo11.  My problem is that when I look at this map in BaseCamp, I see no topo lines, just really blocky, jagged roads.  What am I doing wrong? I'm new to this.  Using a Montana 650T, my PC is Windows 7, just downloaded whatever the current version of BaseCamp is from Garmin website.
