Its extreme range and accuracy make it a must-have for anyone who spends a lot of time on the highway. Pros: Incredible long-range detection: The standout feature of the UNIDEN R4 is its exceptional long-range detection. It consistently picks up radar and laser signals well in advance, giving me plenty of time to adjust my speed. Even on wide, open highways, this detector can pick up signals from several miles away, which has saved me from speed traps more times than I can count. Accurate and reliable alerts: The R4 provides highly accurate alerts with minimal false alarms. It does a great job filtering out unnecessary alerts from automatic door sensors and other non-threat sources, which is often a problem with cheaper detectors. The advanced filtering technology ensures you get alerted only when it matters, keeping the ride smooth without constant beeping from false signals. Multiple radar bands covered: The R4 covers a wide range of radar bands (K, Ka, X, and laser), ensuring you’re protected from virtually any radar gun or speed trap. The inclusion of laser detection is a big plus, especially for drivers in areas where law enforcement uses advanced speed detection technology. GPS functionality: The built-in GPS is incredibly useful for storing your driving history, as well as for marking red-light cameras and frequently encountered speed traps. You can also mute alerts in certain areas (like near your home or office) where you know the signals aren’t threats. This further helps reduce false alerts and keeps your focus on the road. Customizable alerts and settings: The R4 comes with a range of settings you can tailor to your driving style. Whether you prefer quieter alerts, different volume levels, or specific radar sensitivity, this detector allows you to fine-tune the experience to your liking. I found the voice alerts to be especially useful as they allow me to keep my eyes on the road while staying informed of any nearby threats. Cons: Learning curve for settings: While the customization options are great, they can be a bit overwhelming for new users. The menu isn’t the most intuitive, so you might need to spend some time with the manual to fully understand and utilize all the features. Once you get used to it, though, the customization becomes a huge advantage. Tips for Use: Mount the detector high on your windshield: For the best range and detection performance, place the detector high on your windshield, just below the rearview mirror. This helps the R4 capture radar and laser signals from farther distances. Regularly update the firmware: Make sure to keep the firmware updated through UNIDEN’s website. The updates improve the filtering, GPS database, and overall performance, keeping your detector current with the latest threats. Customize the settings for local laws: Depending on your area, you may want to adjust the radar bands or sensitivity settings to align with local enforcement methods. This helps ensure you’re only getting the alerts that matter most. Overall Experience: The UNIDEN R4 Extreme Long-Range Laser/Radar Detector has been an absolute game-changer for me. It offers fantastic long-range detection, and its accuracy and advanced filtering system ensure you’re alerted to real threats, not just random signals. The GPS functionality and customizable settings are invaluable, allowing me to personalize my driving experience and further cut down on false alarms. It’s especially helpful for anyone who regularly drives on highways or in areas with heavy law enforcement presence. Though it’s a bit of an investment, the performance and peace of mind make it well worth the cost.

Can this radar operate wirelessly (by batteries) without car cigarette lighter adapter? I have Tesla Model Y so don't have a cigarette adapter.** A: No. Also, you have a cigarette lighter in the middle console. I have a model 3. Bought a phone mount and stuck it to the back of the screen, and got a long flat cord for the radar detector and tucked it in to the middle console trim and run to the plug on the inside. **Q: Are these 'brand new' units ? uniden says they will honor warranty as long as the unit is purchased brand new.** A: The one one that i received was brand new. **Q: Folks that got new units, who was the seller?** A: It’s normal **Q: Looking for stealth technology. Is there anything out there that will disguise my car as an ostrich when going faster than speed limit?** A: No. There are laser only that scramble the signal. Very expensive and only justified if you have a lot of laser guns in your area ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive Long-Range Detection *by B***N on September 30, 2024* The UNIDEN R4 Extreme Long-Range Laser/Radar Detector is one of the best radar detectors I’ve used, offering excellent performance, reliable alerts, and plenty of features to keep you aware of speed traps and law enforcement presence on the road.

This Uniden greatly reduces (not perfect) false alerts and detects radar 1-2 miles away. Expensive, but well worth it 👍 ### ⭐⭐⭐⭐⭐ Outstanding product *by S***Y on March 23, 2024* I tried several detectors, even much more expensive ones. The R4 is my choice. It’s small and good looking, upgraded tech has great range and filters out the garbage signals automatically or manually and is especially good blocking aggravating trash signals coming for other cars. And when it does get a legit threat it’s on it a mile away. Other detectors have arrows, and that would be nice, but those can give off confusing signals. With the R4 range you soon get where you can tell by the signal pattern if the threat is in front, rear, or to the sides, (and the threat sounds are just cool.) This little baby is solid, huge memory for storing mutes, will itself recognize and store a false threat location after a few passes, will pretty much be quiet as a mouse until approaching a real threat. At that point the direction is not as relevant as slowing down anyway. I live in a section that uses Ks and Kas, didn’t know this till R4 educated me, so I can’t turn off the K band, but my R4 will not sound a signal from another car like I found that others do. I don’t speed much but I will get liberal with the speed limit sometimes, and that has cost me hundreds in the past With the R4 you really feel like you have and R2D2 on your side. ## Frequently Bought Together - UNIDEN R4 Extreme Long-Range Laser/Radar Detector, Record Shattering Performance, Built-in GPS w/AUTO Mute Memory, Voice Alerts, Red Light & Speed Camera Alerts, Multi-Color OLED Display, Black - Uniden RDA-HDWKT Radar Detector Smart Hardwire Kit with Mute/Mark Button, LED Alert and Power LED R8w, R8, R7, R4w, R4, R3, R1, DFR9, DFR9BLK, DFR8, DFR7 and DFR6 - SDSACZMU Radar Detector Mount, Rearview Mirror Rod Radar Mounting Base, Suitable for Uniden Radar Models --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/383164416-uniden-r4-extreme-long-range-laser-radar-detector-record-shattering](https://www.desertcart.com.ar/products/383164416-uniden-r4-extreme-long-range-laser-radar-detector-record-shattering) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
