RL360i Radar Detector – Fully-integrated 360º radar protection


The ultimate in speeding ticket protection, with four hidden receivers, 18 unique settings, hundreds of customizable options

A radar system so complete, you’ll fly down the road surrounded by a virtual forcefield of protection. An installation so discreet, your friends will ask if it came with your vehicle. That’s the K40 RL360i.

  • Directional Awareness — Know exactly where the police are at all times – dual radar receivers provide directional awareness and increased range to keep you protected from radar threats – two discreet LEDs indicate front (left light) or rear (right light) radar, accompanied by an audio alert that states “front” or “rear” as well as the specific band of police radar.
  • K-Band Filter — The RL360i intelligently recognizes and rejects radar-based safety features from other vehicles and your own vehicle so you remain focused on real radar threats.
  • Traffic Sensor Filter — The RL360i will reject alerts from traffic flow sensors usually encountered during highway driving.
  • K40 front and rear OEM-like Visual and Auditory Alerts — The RL360i 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 RL360i warns you based on your preferred settings. Choose from five customizable LED brightness settings, voice or tone alerts, or muted audio.
