Vision and non-vision cars can (and generally do since mid last year) run the same firmware.The software on vision cars doesn’t use radar, so installing it will do nothing. The question is, why would you want it? IIHS has already rated the vision cars as safer than radar cars. The only thing radar would get you is conflicting sensor info which leads to more phantom braking… and a higher price tag.
Use of a radar is simply determined by a car's configuration (0=radar, 2=no-radar).
