So it actually is possible for the RMR to make something display on a radar gun. Watch this video and skip to about 0:52. You can see the RMR Phazer make a speed show up on an old MPH gun. I tried it with the C495 and found that if you get things lined up just right, it can make speeds show up on variety of different radar guns. Here's a really long and unedited video of me playing around with it one day so you can see what I saw if you like. So you could argue that the RMR detectors are doing something. However, making a number show up on a radar gun isn't a big deal. You'll find the same thing happen if you point a radar gun at the AC fan in your car. You'll see a speed pop up if you aim the radar gun at a tuning fork which is what cops use to test their radar guns. Using the same principles, you'll also find the radar gun picking up the vibrations from a speaker and displaying those vibrations as a speed too. So while the RMR detector did seem to do something on radar (something I didn't find to be true whatsoever on laser), being able to make a fake number show up on a radar gun at point blank is completely different than interfering with the radar signal from a radar gun reflecting off of your own moving vehicle and thus "scrambling" the radar gun. This is why I say that yes it's technically possible for the detector to display a speed at point blank range, but in no way, shape, or form will it work against a moving vehicle and interfere with a police officer's radar gun when out on the road.
