If you've owned a regular radar detector, you know the hassles of setting it up and hiding it from thieves when not in use. You hate the dangling cords, suction cups and Velcro tabs that destroy the elegant contours of your instrument panel. K40's exclusive "Divide-and-conquer" concept solves all that. Inside the cockpit, separate alert lights and speakers or custom Warning Pod mounts invisibly into your vehicle's instrument cluster. A unique two piece control switch, installed discreetly under the kick panel or in the dash, adjusts the on/off, city/highway, and volume functions.
