The Cobra XRS 9990 digital radar/laser detector offers premium protection and provides you with plenty of information at a glance on its large, easy-to-read display. It offers long-distance coverage with voice warnings, keeps you invisible to detection, and includes convenient features.

The XRS 9990 detects 15 bands from great distances and locks onto those signals quickly — you'll know instantly if you're near one of 7 radar, 6 laser, or 2 safety signal frequencies. You'll get 360-degree laser coverage as well as POP instant-on radar alerts. It also detects nearby strobe lights and safety alert transmitters to indicate when emergency vehicles and safety zones are approaching. You'll even get alerts for upcoming railroad crossings and road hazard locations.

The XRS 9990 offers complete immunity to VG-2 and Spectre I radar detector detection devices and alerts you to their presence. It even gives you warnings on advanced Spectre IV+ technology which also tracks radar detectors.

Informative color graphics
Enjoy the added benefit of 3-D graphics and vivid color with the XRS 9950's 1.0" high-resolution OLED screen. The bright, easy-to-read display features full color visual alerts for specific bands of radar detected, plus important signal strength readouts.

More features
The XRS 9990 also features voice alerts, as well as auto-muting and intelligent muting functions which sense relative speed to virtually eliminate false alerts, and can further reduce the chances of being picked up by a radar detector detector. It also features three city modes to keep false alarms down in urban areas.

A voltage display lets you know when the car battery is running low, and a handy 8-point electronic compass helps you visualize which way you're heading. The XRS 9990 also features an auxiliary audio jack so you can send the audio alerts to an external speaker to help overcome road noise. It can power off automatically to save the battery when you turn off your car, and the built-in memory remembers your settings for an indefinite amount of time without power.

Cobra offers an optional GPS locator for the XRS 9990, which provides alerts to verified locations for speed and red light cameras in the U.S. and Canada.

* new technology


S-XRS Technology: The XRS 9990 is equipped with Super-Xtreme Range Superheterodyne Technology, with super-fast sweep circuitry, to provide maximum detection range, and the best possible advance warning to even the fastest of the instant-on radar guns.

ExtremeBright DataGrafix Display: The unit features a bright, full-color, 1.0" OLED display, with 3D Datagrafix icons providing enhanced data display. You can choose from 5 different color schemes to match your dash illumination: red, blue, orange, green, or multi-color. You can also choose between 3 levels of brightness, and the length of time before the display timeout takes effect: 15 or 30 seconds, 1 or 3 minutes, or Always on. When the display times out, it goes dark, except for one moving dot.

Instant On/Pop Alert: The detector is designed to detect Instant-On speed monitoring signals, which suddenly appear at full strength. Pop Alert provides protection against the new K & Ka Pop mode (single pulse) radar gun signals and provides super-fast, instant-on detection. During a Pop alert, the detector will continue to detect other signals. Note: Radar guns have a much shorter range when in the Pop mode, so appropriate action should be taken immediately whenever a Pop alert is given.

Strobe Alert: The XRS 9990 will give you advanced alert of the presence and/or approach of emergency vehicles. This is a Cobra exclusive that works with the tens of thousands of emergency vehicles currently equipped with traffic light controlling strobe emitters, which activate red lights at traffic intersections in emergency high speed situations.

Safety Alert: The Cobra XRS 9990 will give you advanced alert of the presence and/or approach of emergency vehicles, trains, and road hazards from systems equipped with Safety Alert Traffic Warning System transmitters.

Visual Alerts: The display includes the type of signals detected and a numeric indication of the signal strength from one (weakest) to five (strongest).

Voice/Tone Alerts: You can set the unit to sound alerts and confirm user settings with either a Voice or a Tone alert. The Voice Alert provides specific band annunciation, in addition to tones. Tone Alert provides tones only. A distinctly different tone is used for each type of signal detected, and with radar bands, the tones will repeat faster as you approach the signal source.

LaserEye: The top-mounted LaserEye provides you with 360° degree detection of laser signals. When mounting the unit, you much make sure the LaserEye has a clear view to the front and rear of the vehicle.

VG-2/Spectre I/IV+ Protection: The XRS 9990 will alert you when VG-2, Spectre I, and the new Spectre IV+ radar detector detection (RDD) are in use near your vehicle. The unit is undetectable by VG-2 and Spectre I devices, but can be spotted by Spectre IV+ RDDs. During an alert, the unit continues to detect other signals. You can choose whether or not you want the unit to show VG-2 and Spectre I and IV+ alerts and whether or not to sound audible alerts.

Easy-Set Programming: Easy-Set Programming gives you quick and easy access to all the settings on the unit. The Menu is divided into two sections:

  • User Settings: City Mode, IntelliMute/IntelliMute Pro, iMute/iMute Pro Activation Set Point, Auto Mute, Alert Type, Display Timeout, Frequency Display, Magnetic Compass, SmartPower, Speed Units*, Restore Factory Settings
  • Alert Settings: Pop Detection, X-band, K-band, Ku-band, VG-2, Spectre I/IV+ Detection, Safety Alert, Low Car Voltage Warning, Caution Area Alert*, Speed Alert*, GPS Database Information*, Delete All User Locations*

    * if optional GPS Locator installed

"System Ready" Prompt: When the unit is first powered on, the detector goes through a series of self tests. If successfully completed, a "System Ready" prompt occurs and the unit is ready to begin detecting.

Auto/Manual Muting: When Auto Mute is On, the unit automatically reduces the audio volume of all alerts after they have sounded for four seconds. The signals will remain muted for as long as the signal is detected. When manually muting, you must press the Mute button while a signal is being received. This will reduce the volume of the alert in progress. The volume will return to normal for the next signal.

IntelliShield: The XRS 9990 features IntelliShield to reduce the number of false alerts in densely populated areas caused by microwave relay towers and automatic door openers. In addition to a Highway mode, the unit has three levels of City modes:

  • City X: sounds a single beep when the X-band signal is first detected. The alert then sounds when the signal strength reaches Level 3
  • City X Beep Off: prevents all X band audio alerts until the signal strength reaches Level 3
  • City X+K: combination of City X mode with prevention of K band audio alerts until the signal strength reads Level 2

IntelliMute: IntelliMute allows you to avoid alerts you don't need to hear because you are either stopped or moving slowly. By sensing the RPMs of the engine, IntelliMute knows that you are driving at a low speed and automatically mutes all alerts (except for strobe signals from emergency vehicles). You must first set an activation point for your engine's RPMs, and when the revs go below that point, IntelliMute begins muting. Once set, the activation point is stored in memory.

IntelliMute Pro: IntelliMute Pro prevents detection by radar detector detectors (RDDs), such as VG-2, Spectre I and Spectre IV+, when travelling at slower speeds. When IntelliMute Pro is on, and engine RPMs are below the IntelliMute Pro's activation point, the detector's radar detection circuits are turned off to prevent detection by RDDs. In addition, no alerts will be given at RPMs below the activation point.

8-Point Electronic Compass: The XRS 9990 includes a 8-point electronic compass that automatically provides an accurate direction reading.

SmartPower: The SmartPower feature, when activated, puts the unit into Standby mode for about 15 minutes after the car's engine has been turned off. After 30 minutes in Standby mode, the unit will automatically shut off.

Car Battery Low Voltage Warning: In addition to displaying your vehicle's electrical system voltage, the detector can provide a warning that the battery is low so timely steps can be taken to correct the problem. The "Car Battery Low" alert is triggered when the voltage drops below 11.9 volts. Following the alert, the detector enters the SmartPower mode to avoid future draining of your car battery.

External Speaker Jack: You can connect an external speaker or earphone if the detector is to be used in an environment with high ambient noise levels. A 2.5mm sub-mini jack is provided.

Mounting: You will get optimum performance from the detector if you mount it at a point approximately in the center of the vehicle, as low as possible on the front windshield without obstructing the view of the road to the front or rear. The detector can be mounted in two ways:

  • Dashboard Mount: Using the supplied Velcro pad, you can attach the detector to the dashboard.
  • Windshield Mount: The supplied windshield mount adheres the detector to the windshield with two suction cups. The angle can be adjusted for best visibility.

Optional GPS Locator and AURA Database: The XRS 9990 is compatible with the optional GPS Locator (Cobra part # RDA GPSL55) and AURA Camera and Driving Hazard database. The GPS Locator simply plugs into the mini-USB port on the side of the radar detector, and warns the driver of fixed speed and red light cameras, speed traps, and dangerous intersections across North America. The AURA database is updated daily and provides the industry's most complete and accurate coverage and reliability. A subscription is required in addition to the purchase of the GPS Locator.
