Not exactly. What they said was that the -2020 device requires a stronger signal than the -250 so the -2020 "cannot be painted" and "may need to be mounted externally" to achieve adequate signal strength. I would say this depends greatly on your installation. If you're replacing an existing -250, I'd just swap it out and see what happens. If that doesn't work then you might need to explore another mounting location.
In my RV-4, with the -250 mounted on the turtleback under an open canopy, I'm betting there won't be any problem. But, I kinda like the idea of keeping the 250 installed and adding on the -2020. That will require another location and, based on the recommendation, I'll probably put that in the open further back on the fuselage.
