- Reviews & Testimonials
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.
GPS Features — The RL360i offers you 17 customizable settings, including GPS features such as:
- Mark to Mute – Mute audible warnings of false, non-police radar locations you regularly travel past with a simple button push.
- Quiet Ride – Mute alerts under a pre-selected speed. Eliminates alerts when you plan to drive near, at or below the posted speed limit.
- Mark to Alert – Mark dangerous intersections, speed traps, school zones, and red light cameras.
- Speed Monitor – Track your speed without taking your eyes off the road.
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.
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…contact us for a dealer referral.
Optional K40 Laser Defuser protection — Become invisible to police laser guns. The RL360i, combined with the jamming power of the Laser Defuser units, delivers the ultimate in ticket-free radar and laser protection.

Every mile I drive in my Porsche is more enjoyable thanks to the K40 radar/laser system. I’ve been warned several times of speed traps in the first two months of it being installed.
The K40 units installed in my cars are just what the doctor ordered to maintain situational awareness on city, country and highway roads. Considering the amount of miles I’ve driven in the One Lap of America, to and from road courses for HPDE’s, K40 has kept me ticket free over the years. I am more than pleased with your products, technical support and most importantly, your customer service.
(Currently owns 8 vehicles with complete K40 radar/laser systems)
I have your product on my BMW, and love it. It allows me to drive the car the way it was made to be driven. I spend less time looking for speed traps and roof lights, and more time with my eyes on the road.
Dear K40 –
I was test driving a Porsche at MotorWorks in Barrington, IL yesterday, and when discussing pricing for the vehicle, I inquired about a K40 system. They handed me a brochure on your new RL Series, which sounds great. The part of the brochure that made me laugh was the testimonial from the guy on his “Third K40”.
I purchased my FIRST K40 when in high school for my Olds Cutlass Supreme. It took me months to save up the money. Ever since then, I have put K40’s in all the vehicles I purchased as well as my work trucks.
1. Cutlass Supreme
2. Merkur XRI
4. Cougar (1st totaled in accident)
5. Ford Expedition (work truck, mobile veterinarian)
6. Jeep Cherokee (ex-wife’s work truck)
7. Dodge Ram 350 (ex-wife’s new work truck)
8. Ford Expedition (2000 new work truck)
9. Cadillac Deville
10. Lexus 470
11. BMW 530 (fiance’s)
12. Ford Expedition EL (2010 new work truck)
So, the RL360 will be my 13th K40 system purchased. Not bad for a regular consumer. Just wondering when you will have a frequent customer discount card? Thanks for keeping us safe.
This system works awesome. Had a Valentine before, and it looks so much better, and works better too.
This is my second K40 radar detector. The first one I purchased in 2001 saved me from a ticket the very first day. I thought it was defective because it alerted me 4 miles before I saw a state patrol. This convinced me how well this product works! It has saved me countless tickets since then. Thanks for making a superior product.

Trying to estimate warning time in an actual mile or feet measurement is impossible since true warning time is influenced by many outside variables that have nothing to do with the radar detector itself. For example, the strength of the radar signal being transmitted, the direction the gun is pointed, the length of time it is transmitting, the positioning of the patrol car, and the influence of other objects around you may all affect how your radar detector receives a signal.
For these reasons, don’t expect your detector to achieve the same warning distance every time you encounter police radar. Just expect it to do what you bought it for: give you enough time to slow down and save yourself from receiving a speeding ticket.
Sensitivity refers to a radar detector’s ability to pick up police signals at the greatest distance. Selectivity refers to the detector’s ability to filter out signals that are not true police signals, yet operate on the same frequencies as police radar (i.e. security alarms, garage doors, automatic doors, etc.).
The filtration software built into K40 radar receivers features very unique microelectronic processors that minimize distractions that come from non-police radar transmitters. This helps give you the time you need to react to real potential threats, without the constant “falsing” that makes other detectors difficult to use in today’s challenging driving environments.
Radar detectors are essentially superheterodyne radio receivers. Like any radio, they’re passive devices that listen for microwave signals. The main difference is that they are specially-tuned to detect microwave frequencies transmitted by police radar and laser guns.
If a police car is not equipped with a radar or laser gun, a radar detector cannot possibly locate it. Also, if no signal is transmitted when you pass the police car, there won’t be any signals for your detector to receive.
Police may also use a sinister technique called “Instant-On” or “RF Hold.” During this type of encounter, an officer will wait until a targeted vehicle is within range to send a quick burst of radar to clock its speed. K40 radar detectors are sensitive enough to detect these brief, weak signals, but you have to pay attention and react quickly.
Speed signs – or speed reading boxes – are radar-based. Radar detectors are not radar jammers. Jamming radar is a federal offense and is prohibited by federal law nationwide. These informational-only speed readers, if working properly, should always detect and display your speed.
Speed signs – or speed reading boxes – are not used to issue traffic tickets or citations. As a result, these portable systems are not calibrated regularly and can “drift” away from the FCC-authorized frequencies. Because of this, when passing one of these signs that say Your Speed Is…,” you may or may not receive an alert. These devices are primarily placed in residential areas as a reminder to obey the speed limit.
POP Mode, when turned on, enables the detection of a special band of radar known as “POP.” This is a very short transmission signal that allows the user of a radar gun to capture a quick read of a vehicle’s speed prior to setting the gun to another band. K40 recommends that you keep the POP Radar Mode turned off for two reasons: 1) POP radar does not transmit long enough to gather information needed to issue a speeding ticket, and 2) keeping POP Mode “on” is known to cause far more false alerts than actual alerts.
No, we do not. The sale and use of radar jammers has been banned by the Federal Communications Commission (FCC) since 1997. The fines for each violation can reach up to $11,000.
Today, many high-end car manufacturers, such as Mercedes-Benz and BMW, are incorporating special tints into their windshields to protect the interior look and comfort of their cars. Unfortunately, this creates a very real problem for people who own portable radar detectors.
Putting tint of any kind on your windshield that contains metal film is essentially like putting a blanket over your radar detector. While radar microwave signals can still travel through fiberglass, plastic, and glass, they cannot penetrate metal. Some tints are worse than others, but if it contains metal of any kind, it will reduce the performance of any portable radar detector mounted inside the car.
