At first glance, it’s lot smaller in real life than in pictures. The screen is crisp and bright. You have to turn up the volume to 7 or higher otherwise it’s too quiet. The power cord is finally on the right side or the correct size. WiFi updates are quick and easy. There’s so many settings to keep most enthusiasts happy. This is by far the longest range radar detector. You’ll also learn the name of the laser gun when you get your first ticket.Initial setup is a little wonky. The latest version of Mac OS doesn’t work for firmware update. Even if you’re successful installing it and you will need an update to get all your photo radars as well as additional K block frequencies.In order to enable WiFi you will need to pair Bluetooth. You can’t search for Bluetooth using your phone. You need to download R/TACH from the App Store. Once you pair Bluetooth using the App and set up your WiFi, it’s a breeze. Downloading firmware and database is super quick, painless and fast.

Great radar detector! Its reliable, durable, can hear it over loud music. I also have my dash cam plugged into the usb port of its power cord, and both devices work perfectly sharing the power source.Only time this radar detector doesn't work is when going thru this one area while on the highway, a certain police unit turns their radars off and clocks people!! 😂😒There have been SEVERAL times the Ka band was going off and I'm looking like "where is this cop" for what seems like a while, and eventually I see them. Definitely long enough range for a suitable warning!!And it sure does pick up everything: speed cameras, those speed radar signs, traffic light cameras, etc. It's really easy to hit "mute" for these things, and it automatically does a "mute memory" so u don't have to listen to it every time passing the same spot. It is also easy to remove mute memory by hitting "mute" again the next time you.I was actually intimidated by the manual and all the settings at first. However, I've left it on the default "highway" and it's all good. All I ever needed to touch is volume buttons and mute/dim button, which were easy enough to learn just by simply pressing them. And also going into menu to set up wifi/bt if u install the app, which wasn't that bad, just a lot of scrolling to the actual setting.

So worth the money, it is pretty accurate on where the cops are at. I believe it even warns you about speeding cameras as well. I would buy again.

Would highly recommend using the R4 Companion app. This radar detector can be configured to be very quiet alerting you to only when it definitely is a radar gun. Every radar detector has false alerts, but this one has barely any.

I recently purchased the Uniden RW4 radar detector to replace my over 10-year-old Escort model, and I couldn’t be more impressed. The setup was straightforward, and the device’s features are extensive enough to keep me exploring its capabilities for a while. The RW4 delivers exceptional performance, with advanced filtering and long-range detection that surpasses my expectations.The only minor issue I encountered was registering the radar detector on Uniden’s website. The RW4 isn’t listed yet, so I had to register it as an R4 instead. While this was slightly inconvenient, it didn’t detract from the overall experience.Overall, the RW4 is a fantastic upgrade and well worth the investment. Highly recommended!
