Key Features
MILES AHEAD OF THE COMPETITION.
Blackfin® DSP — Extreme Long Range
The R4W is powered by Uniden's Blackfin® Digital Signal Processor — the same technology used in military-grade communications. It delivers extreme sensitivity and early threat detection that outperforms most detectors in its class.
Built-in Wi-Fi — OTA Updates
The R4W connects to your home Wi-Fi to automatically update firmware and the speed and red-light camera database over the air — no cables, no computer required. Always up to date, always accurate.
GPS with Auto Mute Memory
Built-in GPS remembers locations where you've manually muted false alerts — like grocery store door sensors — and automatically silences them every time you pass. Quieter ride, smarter alerts.
Red Light & Speed Camera Alerts
A preloaded database of red light cameras and speed enforcement zones gives you advance warning before you reach them. Free updates keep the database current via Wi-Fi.
Advanced K/Ka Band Filtering
The R4W uses the best K/Ka band filtering in its class — dramatically reducing false alerts from blind-spot monitoring and collision-avoidance systems found on modern vehicles. Fewer false alarms, better real threat detection.
Multicolor OLED Display
The bright, high-contrast multicolor OLED display shows band, signal strength, frequency, and speed simultaneously — easy to read at a glance even in direct sunlight or complete darkness.
Bluetooth & R/TACH™ App
Connect via Bluetooth to the R/TACH app on iOS or Android to customize settings, view red-light and speed camera locations on a map, manage updates, and review alert history — all from your phone.
Programmable Voice Alerts
Voice alerts clearly announce radar band and threat level so you can keep your eyes on the road. Fully programmable to match your style — hands-free awareness at highway speeds.
Auto Learn — Quieter Over Time
The R4W's Auto Learn feature identifies and learns false alert sources along your regular routes — getting smarter and quieter the more you drive. Up to 2,000 mute memory and user marks stored.
Blackfin® DSP
Extreme Range.
The Uniden R4W is consistently rated as one of the highest-performing single-antenna radar detectors ever tested. The Blackfin® DSP processes signals faster and more accurately than conventional chips — giving you more warning distance to respond safely before you're in range.
Why R4W
THE CONNECTED
DETECTOR THAT
GETS SMARTER.
The R4W isn't just a radar detector — it's a connected platform. Wi-Fi updates, Bluetooth app control, GPS lockouts, and Auto Learn technology combine to give you the quietest, most accurate detection experience available at this price point.
