Use your iPhone to stay ahead of threats

Imagine: a radar detector that stays out of sight and delivers warnings to you right through your iPhone. Cobra's iRadar S-Series detector makes it easy to cruise without a cluttered windshield, while still keeping you informed of upcoming threats. Download the free Cobra iRadar app from the iTunes® App Store — the detector links to the app using your iPhone's Bluetooth® wireless connectivity. Once connected, the app will let you view all alerts and functions on your smartphone's display, including signal strength, settings adjustment, alert history, and warnings for upcoming verified speed and red-light cameras.

Cobra iRadar S-Series radar detector

You'll see the info you need in an instant on your iPhone through the Cobra iRadar app.

Trustworthy protection, hidden from view

The weather- and waterproof iRadar S-Series installs under your vehicle's hood, so nobody will know it's there without looking for it. And since it communicates with your iPhone via Bluetooth, you don't have to route any wires through your car's firewall to maintain a connection. Simply pair your phone with the detector when you're in the car, fire up the iRadar app, and you're ready to roll. The Bluetooth connection with your iPhone will not affect your ability to receive or place calls.

The S-Series gives you 14-band radar and laser protection, including POP mode and safety warnings. Super-fast circuitry ensures you'll have long-distance protection and rapid delivery of alerts. You'll receive visual cues through your phone, and you can elect to have voice alerts spoken to you through your phone. You'll also be protected against VG-2 and Spectre I radar detector-detection devices, and get alerts as those threats approach.

Everything through your phone and app

The iRadar app gives you the choice of Dashboard or Map view to best suit your driving style. The app also connects you to Cobra's AURA database of thousands of camera locations across the U.S., so you'll get warnings when red-light and speed camera or known enforcement areas approach, even if you don't have the detector turned on. The app also stores a history of spots where you've had alerts, warning you as you approach them in Map View, so you can drive with confidence. The built-in speedometer and compass help you keep track of your velocity and bearings.

Tap into the Cobra iRadar Community

Millions of other drivers are using the iRadar app on their smartphone as they travel, so why not use their information to help yourself? iRadar users can tag a detected radar or laser signal or enforcement area on their own phones, and that location is uploaded to Cobra's central server. Your app then can incorporate those locations into its own maps and give you a heads-up when you're approaching them.

More benefits of the Cobra iRadar app

Do you also connect your phone to your car stereo to enjoy your music? The iRadar app lets you control your phone's music without ever leaving the app, so you can play, pause, or advance tracks while enjoying uninterrupted protection. You can also have the app remember where you parked your car so your phone can lead you back to it after you've spent time at a big shopping mall, amusement park, or sporting event. And select A/V receivers from JVC will allow you to see the display of the iRadar app on the receiver's screen when the receiver's in "App Link Mode."

Sorry, but we cannot ship radar detectors to Virginia or the District of Columbia.

Product Research


Overview: Cobra iRadar provides radar/laser detection technology that you can integrate with your iPhone or iPod touch. The Cobra iRadar S120R is an under-the-hood radar/laser/camera detector which uses Bluetooth wireless technology to connect to your iPhone to display radar alerts, control settings, log alert history, and be warned of upcoming speed traps and red-light cameras. The S120R has limited functionality with iPod touch, and is not compatible with Android devices.

Cobra iRadar App: Cobra iRadar is a large community-based radar/laser/camera detection system. When linked to the Cobra iRadar detector, users can share and receive alerts in real time from other iRadar users. Cobra iRadar provides the following features:

  • Provides alerts from and access to AURA, Cobra's exclusive and 100% verified camera and driving hazard database of red-light cameras, known speed traps, and dangerous intersections.
  • Displays visual alerts from the detector on your smartphone.
  • Displays live radar and laser alert information from all iRadar users.
  • Allows you to submit and receive locations of live police, red light cameras, speed cameras, and caution areas from other members of the iRadar community.
  • View alert history on the radar map view.
  • Control radar detector settings from your phone.
Note: The Cobra iRadar app is compatible with iPhone and iPod touch, and requires iOS 5.1 or later. Location-based alerts and GPS settings are available only for iPhone. Only radar/laser alerts and settings will work with iPod touch.

Pairing: Once the Cobra iRadar App is downloaded to your iPhone/iPod touch and the unit powered on, the iRadar unit will appear in your device's Bluetooth settings menu. The detector's LED will flash blue during pairing and will turn solid blue when pairing is completed.

Radar/Laser Detection The Cobra iRadar S120R provides detection for all radar and laser guns: X, K, Ka, VG-2, and Laser.

City/Highway Modes: The Cobra iRadar S120R utilizes the following modes to reduce false alerts: City X, City X+K, City X+K+Ka, City Max, and Highway.

Dashboard: The Dashboard feature displays speedometer (digital and analog), compass, and car battery voltage on your phone's LCD screen. When a radar/laser alert occurs, the unit will sound a tone or voice alert, and the display will indicate the type and strength of the detected signal.

View Map: You are able to view user-marked locations, red-light camera locations, speed trap locations, caution areas, and GPS-based speed and direction of travel on your phone. You can also view traffic patterns along major highways. While traveling with the map view on your display, you can even control the music on your smartphone with on-screen buttons.

Settings: The Settings page lets you configure the iRadar S120R detector and the iRadar app to your preferences.

Mounting Options: The S120R is designed to be discreetly mounted inside the engine compartment. It is waterproof, weatherproof, and designed for harsh environments. An L-shaped mounting bracket is supplied to mount the unit in the front of the engine compartment behind the grille. Mounting hardware and wire ties are also included.

Power Requirements: The Cobra iRadar S120R includes a 12' power/ground cable with an in-line fuse for connecting directly to the vehicle's 12-volt electrical system. No wiring is required in the cab of the vehicle.
