Yes, I got that. It’s not the right way to refer to the radar device. “Projecting” isn’t a great word to use either.

Again, display options are options on the head unit.

All the different radar devices are providing the same data. That’s why you can mix-and-match head units and radar devices. (Manufacturers of these are not going to be able to ask head unit manufacturers to make programming changes.)

Garmin head units don’t provide many display options. The only thing appears to be on which side of the screen the “cars” are displayed.
