New at Basecamp and have downloaded MYTRAILS(MO) which has many of the trails I am after. However when I bring it up in base camp I have the trails but no underlying topo map picture . I may be missing a concept here so please help me understand. I imagined that mytrails would overlay on some sort of topo map, but I can only select one map at a time and mytrails does not have the topo under it????

Short answer: your GPS will allow you to choose more than one map at a time but Basecamp will not.
