Hello! Can this radar operate wirelessly (by batteries) without car cigarette lighter adapter? I have Tesla Model Y so don't have a cigarette adapter.
Are these 'brand new' units ? uniden says they will honor warranty as long as the unit is purchased brand new.
Folks that got new units, who was the seller?
Looking for stealth technology. Is there anything out there that will disguise my car as an ostrich when going faster than speed limit?

Reliable and Accurate – A Must-Have for Frequent Drivers

California customer here. I've used the UNIDEN R4 on several extended road trips, each over 400 miles, and it has consistently delivered outstanding performance. The detector provides impressive range and accurate alerts, giving me plenty of time to adjust speed when needed. While it's impossible to know for certain how many tickets it may have saved me from, there were definitely multiple situations where it proved invaluable. For anyone who drives long distances or at highway speeds frequently, this device is well worth the investment.

Outstanding Distance Coverage

I purchased this on reviews. I replaced my cobra unit.I did the software update, tweeked the settings. Ka, Lazer burst and X . My area has Ka 5G repeaters ( i can't filter this out ) that's my problem not yours.This little unit is crazy good. I've used it over a month before writing this.The long range is outstanding, I daily take an off ramp that goes up then curves to the left and drops down, this little guy picks up radar signals while pointing away from the source 2 minutes before they come into view. I have 6 regular spots for CHP hangouts on the way home. I now were they are with this R4.

Impressive Long-Range Detection

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. 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.

R4 now has BlueTooth!

Few know that this radar detector, the R4 has BlueTooth and can be connected to your smart phone and the Uniden R/Tach app, as well as the R4 Companion App (paid app). You must update it to the latest firmware for the BlueTooth option to show up. Bottom line is this detector offers so much more once you update it. It is already an amazing detector with amazing features. For more info on the update just do a search and you will see. Uniden designed this detector with BlueTooth for a later update and that update is now!

Solid and Very User Friendly

I got the Uniden R4 after losing my R3 in a wreck , and I have to say, this scanner is a real winner. I’m not a tech expert, but this thing is super easy to set up and use right out of the box. The audio quality is surprisingly clear, which is a big plus when you’re trying to pick up important transmissions.One of my favorite features is its wide frequency range. It picks up everything from local public safety to weather channels, which means I’m always in the loop about what’s happening around town. The scanning speed is pretty quick too—I never have to wait long to catch a transmission.I also appreciate the intuitive interface. The buttons and display are straightforward, and I was able to customize my channel list without any hassle. The build feels sturdy, so I’m confident it will hold up well over time, even if I take it along on trips.All in all, if you’re looking for a reliable, no-fuss scanner, the Uniden R4 is definitely worth checking out. It does exactly what I need without any unnecessary complications.

Like not Love here’s why….

LIKE not Love only because of false alarms. BUT to be fair I haven’t updated in a year and I believe it has better capabilities now just a pain for me because no computer. I wish they had had an R4W. Wi-fi then. But overall happy. The first day I used it it saved me two lanes heading in the same direction I was in the fast lane and it started beeping so I slowed down and got behind a car that was actually passing me as soon as I changed lanes and started beeping faster and I gave him highbeam flashes, but he just kept going about 70 in a 55 and sure enough around the corner state patrol unmarked pulled him over. I was bummed for him but laughing out loud for me because that absolutely would have been me getting a ticket so it paid for itself the first day I used it and has saved me several times since I don’t speed around, but I do find myself going a bit over and it’s just peace of mind worth having
