Is the 2015 Explorer console a direct mount? How does it preserve cargo space? Is it just shorter in height than the Navi console?
Yes it bolts to the floor. You may need some sort of custom bracket arrangement to make sure it's safely secured. What makes this design different is the way the lid opens. On our 2015 Explorer 2nd row console the lid was hinged at the *front* so that when it opened the overall height of what remained matched the height of the seats on either side.
I don't remember the Explorer having "Cargo" mode for the 2nd row seats. With the seats folded all the way down in an Expedition, I don't know whether or not an Explorer console would stick up higher than the seats on either side. You might have to try it to find out.
Here's a video on the Explorer console. This says it's the 2016+ style. I don't know how much that differs from 2011-15. Note the same console may also be used in the Ford Flex:
