The Uniden R4 is an all-new platform with a much greater range of detection. It has an enhanced Auto Mute Memory feature, which automatically locks out false alert locations. The R4 also has the best collision avoidance system in the market, offering fewer false alerts from blind-spot monitors and K Band sensors in other vehicles. When you need the best information possible, and none of the noise, Uniden’s R4 Extreme puts you miles ahead.

  • BUILT-IN GPS WITH AUTO MUTE MEMORY
    The R4 can remember and automatically mute false alerts (such as retail store door alarm), along your routes so you never have to listen to the same false alert twice.
  • MULTI-COLOR OLED DISPLAY
    An easy-to-read display allows for more useful information to be displayed at once, improving your overall situational awareness.
  • VOICE ALERTS
    Voice alerts provide clear communication allowing for hands-free operation. Voice alerts are programmable to fit your style so you can keep your eyes on the road with no distractions.
  • ADVANCED K/KA BAND FILTERING
    The R4 has the best K/KA Band filtering resulting in fewer false alerts from blind-spot monitoring and collision avoidance systems.
  • RED LIGHT/SPEED CAMERA ALERTS
    Pre-loaded Red Light and Speed Camera locations with free database and firmware updates ensure your radar detector will always be up-to-date.
