I am from New York state and travel a lot in Ontario and purchased a Sti Driver for this reason. My first trip into Ontario did not go so well. I was on the only car traveling on a country road when a cop went by in the opposite direction. I was not speeding and did not hit my brakes. The cop pulled my over and demanded the radar detector. Should he have been able to detect this unit? Could it have been a faulty unit and those detectable? This unit was mounted under my hood in a sealed box with the speaker under the dash. The cop was on a mission to find my detector and did. What gives!!
