from what i have seen and tested ( not that i'm done testing or that i might be wrong)
it seems that this software will not load rouetable and non routeable maps at the same time
i have non routeable topo usa and world map and a routeable north america, topo canada and south america
it will not mix the two different types for me
the maps are all built with mapsouce
im still testing so this is preliminary test results..
