Cobra's got you covered

You've got to react quickly when radar's on the horizon, and hearing an audible alert can make a crucial time difference. Cobra's SPX 5500 radar detector not only gives you long-range protection against radar and laser, but it'll also announce what type of band it's detecting so you can make an informed decision without taking your eyes off the road. In addition to warnings for instant-on POP radar, the SPX 5500 also monitors a safety band to inform you of nearby road work, emergencies, and other situations. And you can still check out the easy-to-read DigiView® text display for additional information when you need it.

Cobra SPX 5500 radar detector

Powerful yet elusive

The SPX 5500 offers complete immunity to VG-2 and Spectre I radar detector detection devices, and warns you when they're in the vicinity — you'll also get alerts for advanced Spectre IV+ detectors. The lightning-fast circuitry housed inside its compact chassis alerts you to threats well in advance, and you can follow the 5-level digital strength signal meter to learn how close you are to the signal's source.

Extras for the road

Choose between city and highway modes to keep false alerts to a minimum. Want to keep things quiet? The IntelliMute® feature reduces false alerts based on your relative speed, and keeps your detector free from detection. Turn on the dim mode and give your eyes a break when driving at night.

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

Crutchfield Customer Review (What's this?)

Has already been put to the test, travel over 300 miles every week and has not failed me. Gave it 4 because at times it will go off when there is nothing around, train alarm too, there are no trains in my town! Hasnt missed on the highway though, i dont speed excessively, bu its nice to have a heads up. Well worth the money, love the voice and text, would recommend to everyone.

Pros: Voice and text

Cons: Goes off at times with nothing around

Product Research


14-Band Radar/Laser Detection: The Cobra SPX 5500 detects 14 bands of radar and laser, including the Safety Alert System:

  • Radar: (Visual Display--Band + Signal Strength)
    • X band
    • K band
    • Ka band
    • Ku band
    • Pop Radar
  • Laser: (Visual Display--"L" is steady)
    • LTI 20-20
    • LTI Laser
    • Kustom Signals Laser 340
    • Kustom Signals Laser
    • Stalker LIDAR
    • Laser Atlanta Speedlaser/Kustom Signals-ProLaser II
  • Safety Alert Traffic Warning System: (Visual Display--"S" is steady)
    • Emergency Vehicles, Road Hazards, Trains
  • VG-2 and Spectre I or IV+ (Radar Detector Detectors): (Visual Display--see below)
    • Interceptor VG-2 (V is steady)
    • Spectre I or IV+ (V blinks)

XRS Technology: The SPX 5500 is equipped with Xtreme Range Superheterodyne Technology, with super-fast lock-on detection circuitry, to provide extra detection range, and the best possible advance warning to even the fastest radar guns.

DigiView Data Display: The SPX 5500 is equipped with the DigiView Data Display, a scrolling, 8-character, dot-matrix display with a bright green, easy-to-read alphanumeric text readout. You can adjust the intensity of the display using the top mounted "Dim" button. The detector has a Bright display mode for daytime driving, 2 Dim modes for dusk driving, and Dark mode where no visual alerts will be displayed.

Instant On/Pop Mode Alert: The Pop Mode Radar Gun is a single-pulse Doppler radar that is a feature of a K and Ka (Bee III radar gun) band Instant-On radar gun. It uses a single, short-time pulse to measure the target vehicle's speed. The SPX 5500 can sense Pop radar signals beyond the effective range of Pop radar guns, and will alert you with two beeps and two flashes of the "P" indicator. During the alert, the unit will continue to detect other signals.

Safety Alert: The Cobra SPX 5500 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 text display includes the type of signals detected and a numeric as well as vertical bar indication of the signal strength from one bar (weakest) to five bars (strongest).

Voice or Tone Alerts: The unit will sound alerts and confirm user settings with an audible alert. You can choose either Voice or Tone alerts. In Voice Alert mode, you will first hear several tones, then a voice announcing the type of signal detected, followed by more tones.  In Tone Alert mode, only the tones will be heard. 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 SPX 5500 will alert you when VG-2, Spectre I and IV+ radar detector detection (RDD) is 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.

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.

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 traveling 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.

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 hook-and-loop 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.
