"replaced by BaseCamp"
I don't think BaseCamp replaces Mapsource because
- BaseCamp is freely available whereas you get Mapsource only when you buy a map.
- They don't offer the same functionality (features), compare BaseCamp and Mapsource. That is not to say Mapsource does everything that BaseCamp can do.
