Been using a Valentine One for about 8 years...just updated to the new version....I place mine very close to the center of my windshield....can't really put up on top cuz no direct visible view for the sensor to the rear....
I have a V1 and mounted mine like this in the rear with concealed display in front of me below the visor.. Works very well and no problems at all with detection.
