Hello,
After updating to BaseCamp 2.1.2 on my Mac small trails and unpaved roads are no more visible in BaseCamp. I use the topographic map Topo Schweiz v2 (aka Swissmap).
I'm pretty shure that these trails where visible in previous versions of BaseCamp as I have some stored routes which still use the same trails if they are recalculated. Also new routes still use invisible trails when calculating the route.
Increasing the level of detail in the map does not reveal the trails.
Greetings, Beat
