R4 Radar Detector

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 users need the best information possible and none of the noise, Uniden’s R4 Extreme puts them miles ahead.

Built-in GPS with Auto Mute Memory

The R4 can remember and automatically mute false alerts (such as retail store door alarms) along routes so users 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 overall situational awareness.

Voice Alerts

Voice alerts provide clear communication, allowing for hands-free operation. Voice alerts are programable to fit the users’ style so they can keep their 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.
