I don't know what happened, I found my 8500 is not working!!!
the story is like this: I drove on highway using my 8500 last week, everything looks good. I was driving around 140-180km/h, but suddenly I found there was a Canada RCMP Police Patrol pulled over a car, however, my 8500 even didn't have any reaction on the RCMP patrol. this was the first time, I told myself that maybe officer turned the radar off or he was using Laser Guy at that moment, so there wasn't any reaction on my 8500. I kept driving, later, I found 3-5 RCPM patrol parked at roadside and control the traffic. However, my 8500 didn't have any reaction at all! what's wrong with it? later, I slowed down, because I counldn't believe my 8500 anymore. but when I came back to town, there was speed reminder on highway which was K Band, my 8500 detected that about 4 miles before that. it doubted me more! why there was no reaction on RCMP patrol but very efficient reaction on K Band speed reminder?
the other story happened yesterday, I was driving on highway, there was a RCMP patrol hided at the side lane, heading the coming traffics, when I saw that patrol, it pulled over one guy, when I drove by, my 8500 still didn't have any reaction. I didn't give up, I made U-turn and come back to try again, it still didn't work. what the F it is? (X Band works well in city, K band can be detected if I try it in front of the Automatic Door)
Is it my 8500's problem or Canada RCMP upgrade there equipment? when I first bought my 8500 in Feb this year, my 8500 helped me a lot on highway and detected Ka Band on patrol car.
Can anybody help me out? thanks a lot!
