The Uniden R4 is one of two new Uniden radar detectors, having even higher performance than the Uniden R3, the other new radar detector, is the dual-arrow Uniden R8.

Having more than 14-times the capture distance of a police radar gun, the Uniden R4 provides performance often exceeding all other manufacturers' top performing detectors at considerably less money and is currently the most sensitive single antenna detector we've ever tested!

The result is that the Uniden R4 will provide you with more than ample warning of instant on K and Ka band miles away.

Filtering

One of the main benefits of the Uniden R4 is that it now incorporates an LNA for Ka-band as well as an LNA for X-band and K-band for about a 3dB increase in sensitivity over the Uniden R3.

Easy Advanced Programming Video Tutorial


Programming your Uniden R4 for the specific conditions you drive is easy. Just press the menu button and you can select from various different options that include the sensitivity, the filtering, the brightness of the display and more. You can read a detailed Uniden R4 Review.

Reviewer: Phillip from Brooklyn, NY United States  
I bought the R4 because my R3 was not behaving and I wanted auto lockouts. Uniden has a major problem with over speed warnings that cannot be turned off with speed cameras on. I may be returning it as this is very annoying. Other detectors do not do this.

1 of 5 Shipped and sold defective unit June 21, 2023
Reviewer: goldendeal from Hot Springs AR  
Purchased a Uniden R4 from Radar Busters as after reading on their website they have a satisfaction guarantee that you won't be stuck with a radar that is defective.This is not the case. I have had the radar 3 days and could not hear anything coming out of the radar. I contacted Radar Busters on this issue and it was determined they sent me a unit with a speaker failure. Instead of making this right and sending a new unit to replace the defective one they want me to go through Uniden. A brand new unit! They will not take reasonability for sending a defective unit. I even offered to upgrade to the R7 so they would at least offer to send a working unit. No, I had to go through Uniden which has yet to contact me. Any other vendor would have taken responsibility for sending a damaged radar and replaced unit immediately. Not pass the buck to the manufacture. I have been waiting to hear from Uniden for 2 weeks. The unit is sitting in a box in my living room. $400 plus wasted. Buyer Beware!

RadarBusters Response:

Matthew, we have attempted communication with you several times via phone and have not received a return phone call and have also been working to resolve this issue to your satisfaction.  

We have spoken to Uniden several times and we were arranging to get a replacement detector sent to you, but we have been informed by Uniden that they have attempted to contact you six times and have not gotten a response.  They are going to attempt to contact you again.

We apologize that you received a unit from them that was defective but this is entirely out of our control and unfortunately given the sales volume of these units and the production numbers that rarely one does have an issue.

In the meantime, despite your dissatisfaction, we have sent you a prepaid return label to return the unit to us for a full refund, since arranging a replacement has been difficult at best,
