The best and quietest long-range police radar detector for speeding ticket protection.

Four hidden receivers, 18 unique settings, hundreds of customizable options for your specific vehicle and driving style, and an installation so discreet, your friends will think the system came with your vehicle. The K40 RL360di radar detector is so complete, you’ll fly down the road feeling like you’re surrounded by an invisible force field of protection.

Traffic Sensor Filter — The RL360di will reject alerts from traffic flow sensors usually encountered during highway driving.

OEM-like Visual and Auditory Alerts —

The RL360di retains the original factory appearance of your vehicle’s interior by strategically hiding two LEDs in the instrument cluster and an audio speaker under the dash.  It’s a completely undetectable protection system until the RL360di warns you based on your preferred settings.  Choose from five customizable LED brightness settings, voice or tone alerts, or muted audio.

System Control Options — 

Wireless Remote Control (standard)– The key fob sized wireless remote lets you control everything from the brightness of the alert LEDs to the system’s mute settings and GPS features.  When not in use, you can hide the remote control in an interior storage area or leave it attached to a sun visor via the supplied clip.

Expert Control Unit (optional)– The ultimate in OEM style and convenience!  The Expert Control Unit looks and functions just like factory vehicle controls and is backlit for easy button identification in low light conditions.  Available only through select Expert Dealers like us!

Optional K40 Laser Defuser® protection — Become invisible to police laser guns. The RL360di, combined with the combat power of Laser Defuser transponders, delivers the ultimate in bumper-to-bumper speeding ticket protection.

First integration-ready custom-installed radar detector — The K40 RL360di is the industry’s first custom-installed dual receiver police radar detection system that can integrate with the ADS Maestro RR interface and select Kenwood/JVC radios* to provide a visual and touch on-screen experience.
