UNIDEN R4 Extreme Long-Range Laser/Radar Detector




Uniden has launched its latest addition to the radar detector lineup, the Uniden R4. Building on the success of the previous R3 model, the R4 boasts several improvements, enhancements, and new features that elevate its performance and capabilities on the road. Here’s an in-depth look at what the Uniden R4 brings to the table:


The R4 continues the trend of compatibility with various vehicles and driving conditions, ensuring it works seamlessly for a wide range of drivers.

Sleek Design:

The R4 showcases a refreshed design, featuring a more angular aesthetic with slightly larger buttons on the top for easier access and operation.

Notably, the power cable has been moved to the right side of the detector, providing a cleaner installation, especially for hardwiring setups.

Enhanced Features:

Longer Range and Improved Sensitivity: With the addition of two Low Noise Amplifiers (LNAs), the R4 boasts enhanced sensitivity and extended range, outperforming its predecessor, the R3, in various test scenarios.

Automatic GPS Lockouts: A new feature automatically learns and mutes false alerts after repeated encounters, reducing unnecessary alerts during daily drives.

Auto Mode Sensitivity: The R4 offers an “Auto Mode” that adjusts sensitivity based on driving conditions, lowering sensitivity in urban areas to combat false alerts and increasing it on highways for optimal detection.

Durability and Longevity:

The R4 maintains the rugged build and durability seen in previous models, ensuring a long lifespan and reliable performance over time.

User Satisfaction:

Initial testing and user feedback highlight the R4’s impressive performance, especially in radar detection, offering better range and sensitivity than its predecessor and some competing models.

Environmental Impact:

While not explicitly stated, the continued improvement in radar detection technology could indirectly contribute to safer driving practices, potentially reducing speed-related accidents and their environmental impact.

Installation Process:

The R4’s installation process remains straightforward and largely similar to the R3, making it accessible for both DIY enthusiasts and professional installers.

Price and Availability:

Retailing at $449, the R4 comes at a slightly higher price point than the R3, reflecting its enhanced capabilities and new features.

Due to supply chain issues, initial availability might be limited, potentially leading to a rapid sellout similar to previous Uniden releases.

Final Thoughts:

The Uniden R4 stands as a significant upgrade over its predecessor, the R3, offering extended range, improved sensitivity, and advanced features that cater to both novice and experienced users. While it commands a higher price, its enhanced performance and added functionalities position it as a top contender in the radar detection market.


The R4’s ability to integrate upcoming laser jammers and its Bluetooth capability, though not immediately functional, hint at potential future advancements and expanded functionalities that could further solidify its place as a high-performance radar detection solution.

As with any technology, individual experiences and real-world testing may vary, but the Uniden R4 appears poised to set a new benchmark in the realm of radar detectors, offering an enticing combination of advanced features and performance.
