@ Prestovie... A radar detector is not used to tell you it's okay to speed. If you use a radar detector for this purpose then you will eventually get nailed by any police officer. Sometimes they sit completely passive, as you found out, until they see you and then point their radar/laser guns at your car and light you up at the very last minute. The radar detector is still doing it's job by detecting the radar/laser the police is lighting your ass up with but by then it is way too late. I used to use radar detectors with that mindset and got my share of speeding tickets.
I now use my Valentine V1 as an additional device to help aid in my situational awareness and not as a means to allow me to speed with relative impunity. Since changing my mindset in the use of radar detectors, I have not gotten any speeding tickets in 20 years now (knock on wood). They are awesome devices that can still alert you to presence of police. It is unfortunate you got nailed doing 94 in a 70... hope things will work out for you :thumbsup
