I love my V1 radar detector. It has without doubt saved me thousands that would otherwise been mulcted out of my hide by radar-trapping cops — and it has made driving fun again. But it’s got an issue you probably ought to be aware of.
I suspect other radar detectors have the same issue, too.
More and more new cars now come with park sensors, or collision-avoidance/lane departure warning systems. Some of these systems use — you guessed it — radar or laser signals to sense the presence of objects around the perimeter of the car. These signals constantly emanate from within (and around) the car.
(Watch video here.)
The V1 picks up this “noise” — and false alerts — because it cannot weed out the signals generated by your car’s electronics (which in my experience generate police-type K band signals) and police radar, which is almost always K or Ka band. So, as you’re driving along, the detector is beeping the warning tone for K band — and the LED warning lights are dancing — even when there’s no cop around for miles.
