Today, I received a ticket on KA 35.47.., so 35.5; The unit never beeped once. I entered the highway from and onramp, and there was an officer on the highway doing a speedtrap from the rear! I only got the frequency, because after he pulled me over and gave me the ticket, the STI Driver detected the radar. If he didn't use his siren, I wouldn't have known I was being pulled over (no RVM). Looks like I'll be getting a V1 with a cheetah mirror to keep it quiet, since I doubt the 9500ci or sti-r would've received the signal. I'm just glad it happened in the 30 day return window.
