I've had my Rx65 rev 6.1 for about 2 and a half years now. I've never been lasered with it until this week and got it twice.
First one isn't as much a save. I was only going 8 over and was alerted about 1/3 mile away from where I later saw the LEO. The sound scarred the poop out of me.
Second one was a couple of days later in a spot about 2 miles away from the last laser. I was going 14 over the PSL. The RX65 alerted about 1/8th mile from where the LEO was this time. I was really suprised with the laser detection since I always thought the RX65 had mediocre laser detection. I also don't know how the hell I got out of this one, but hey, I'll take it.
I think I might have a factory freak cause my Ka and K band detection are amazing. Almost all of my radar saves are from at least 1.5 miles away and I have too much time to slow down(not that its a bad thing).
My RD is mounted about 3 inches above the dash in the middle of my windshield. I think my laser detection is good since I drive a Honda S2000. The windshield isn't too far from the front bumper since its a small car.
