BaseCamp 4.7.5 does not support XT2

What however Basecamp unfortunately probably does not have, is the satellite view, I miss very much.

The trick used by many is to have Google Maps open at the same time as working in BaseCamp, toggling between the two as you create a route. Google provides a much better 'big picture' view and its satellite and street views really help with details. Additionally, it is shocking the number of times I see a POI in BaseCamp whose location is way off from what is show on Google Maps and confirmed by its satellite and/or street view.
