Uniden R3 vs. Uniden DFR7

Updated: August 2017

The Uniden R3 is the evolution of the Uniden DFR7. It offers a number of different benefits and improvements over the DFR7. Let’s compare the Uniden R3 vs. DFR7 so that you can decide which detector you should buy or if you should upgrade if you already own the DFR7.

Both detectors come with a more affordable GPS-less version (DFR6 and R1) as well as a more well-rounded GPS version (DFR7 and R3). Both detectors offer identical levels of performance and BSM filtering. The GPS functionality helps around town to filter out false alerts using GPS lockouts and low speed muting, as well as giving alerts to redlight cameras.

Under the hood, the R3 is a very different detector. It’s now digital which affords a variety of benefits over the analog DFR7.

Main Differences

Here’s the main differences between the DFR7 and R3:

  • Significantly longer range with the R3
  • Color OLED Display
  • Improved GPS Lockouts
  • All Threat Display
  • Band Priority vs. Signal Strength Priority
  • New Dark Brightness Option
  • Can filter out all nearby RLC’s at high speed or delete individual alerts
  • 67ms K band POP detection
  • 3 digit (instead of 2 digit) frequency display
  • DFR7 can be had for $299 and the R3 is $399

Let’s run through the differences in more detail now.

Significantly longer range with the R3

The DFR7 was known for being a great performer on 34.7 (the most common Ka frequency around the US), but a little weaker on 33.8 and 35.5. Personally I experience mostly 33.8 and it’s the reason I’ve been running other detectors.

The R3 now solves this issue. It is now strong on all 3 Ka bands, able to surpass even the mighty Redline which is incredible. Check out these test results from the TXCTG.

The incredibly long range performance being provided by the new Unidens mean that it has taken the crown from the Redline as the new king of long range detection. When it comes to picking up radar at a distance to give you plenty of warning time, nothing else on the market can keep up with the new digital Unidens.

Color OLED Display

This new display is now color and can be set to several different color options including red, blue, amber, green, pink, and gray so you can choose what best matches your vehicle’s interior or simply looks best to you.

I also like that it’s sunken in a bit which means it’s less likely to be washed out in direct sunlight.

Improved GPS Lockouts

Uniden R3 GPS Lockouts

The DFR7’s lockouts worked well, but there was an issue with them. Uniden only provided 100 lockouts total and if you do a lot of driving in urban areas, it’s possible to use them up, even if you’re relying on quiet ride (low speed muting) to otherwise filter out alerts. Additionally, the lockouts were designed such that they only covered a set area and if you needed to lock out a long stretch of road such as a speed sign aiming down a straightaway, you may need to create several lockouts to quiet the detector down the entire road. This uses up your already limited supply of lockouts and depending on where you created the lockouts, it’s possible to have gaps between lockouts where the detector is silent, alerts, then is silent again as you enter the second lockout. If it’s a small gap, it can be tough to create a new lockout in the gap because by the time you reach up to create a new lockout, you instead wind up deleting the old one.

The R3 solves these issues. It offers 200 lockouts which may not sound like a ton more, but it now learns the entire length of road from start to finish so you can now just lock the signal out once and the false alert will be completely locked out. In practice I find it to be a big improvement.

On a related note, speaking of quiet ride, muted signals now flash on screen when being muted by quiet ride. This way they better get your attention about a potential alert when traveling at low speeds.

All Threat Display

Uniden R3 Review, All Threat Display

With Escort detectors if you want to see the frequency of the signal, you can generally only see the signal strength of that one signal (maybe a second signal with the Max360). If you want to see multiple signals you can put it into Expert Mode, but you can no longer see the helpful frequency information.

If you want to do this with a V1, there’s no frequency information on the detector’s display at all, but if you pair it with a phone, you can see all the relevant information on your phone’s display. This is awesome for seeing tons of information, but it requires your phone to work.

The new R1 & R3 offer an “All Threat Display” option which allows you to see the band, frequency, and signal strength of the primary signal, as well as the band and signal strength of up to 3 more signals, for a total of 4 signals. Now you can see a bunch of information right on the detector’s display without being required to use a phone. Very handy.

Band Priority vs. Signal Strength Priority

If you have a strong K band signal and a weak Ka band signal, which one should the detector be focusing on? The K band signal because it’s really close? The Ka band signal because it’s more likely to be a legitimate alert?

With the DFR7, the alert priority is on the strongest signal. This is great if you’re encountering a strong K band signal close up, but what if that K band signal is a speed sign or grocery store and the detector picks up a weak Ka signal at a distance? You’ll want to be notified of that.

With the R3, it has the option for signal strength priority like the DFR7, but it also adds band priority alerts (called Ka Priority in the settings) where the alert priority will be Laser > Ka > K > X. Since some bands are more likely to be legitimate alerts than others, if you want to prioritize your alerts that way, you have the option.

New Dark Brightness Option

Both detectors have different display brightness options as well as the ability to turn off the display altogether.

The R3 has a new dark mode option where the display is turned off when no alert is present (except for a tiny blinking dot in the corner to let you know the detector is turned on) and then when the detector gets an alert, it will light up to get your attention.

This is especially nice for if you want to run your detector with the volume turned down so it doesn’t disturb others but you still want it to grab your attention should anything arise.

Can filter out nearby RLC’s when driving on the highway

The DFR7 offers an updatable Redlight camera and speed camera database. One thing it doesn’t offer is the ability to individually delete redlight cameras. Sometimes when you’re driving along the highway, it’s possible to get alerted to redlight cameras on nearby city streets and there’s no way to prevent this short of disabling the RLC alerts altogether. Some detectors (ie. Escorts & Radensos) offer the ability to individually delete RLC’s which is helpful for these purposes. However, the DFR7 you can’t do that. With the R3, on the other hand, you can.

The R3 also offers a “high speed muting” option called RLC Quiet Ride. The idea is when you’re traveling over a certain speed (threshold selectable between 50-85mph in 5mph increments), it will mute RLC’s. Very handy for filtering out nearby RLC’s when you’re on the highway.

67ms K band POP detection

This detector is capable of detecting not only 67ms Ka band POP, but also 67ms K band POP. In reality this feature is almost irrelevant since you’ll virtually never see it in practice and it’s best to disable the feature to reduce false alerts, but it’s the only other detector besides the V1 and Stinger VIP that I’ve seen offer 67ms K band POP detection. Note: It doesn’t detect 16ms K band POP.

BSM Filtering

This isn’t really a difference but I KNOW people are going to ask about it so I’m going to address it.

I’m not sure if there’s a difference between the DFR7 and R3’s BSM filter. Both look to be one of the best around. I personally haven’t run the DFR7 in quite a while because of the weaker performance on 33.8, but running the R3, it filters out the vast majority of vehicles and only seems to false to the GM (Chevy, GMC, Buick, Cadillac) and Honda/Acura vehicles that give every radar detector trouble. It’s also able to filter out K band radar coming out of semi’s which most detectors struggle with.

The big difference I’m seeing is that the increased K band sensitivity with the R3 can be a double-edged sword. Even though its BSM filter is pretty effective, the fact that it’s more sensitive means that it’s going to pick up false alerts. It’ll pick up more stores on the side of the street. It’ll pick up BSM’s farther away and even across the street. Because of this, you have the ability to turn down the detector’s K band sensitivity by changing from Highway to City mode (this is useful both on the highway and in the city, it turns out) to bring the K band’s sensitivity down closer to what other detectors are like. Doing this helps out with the false alerts. In my own experience, driving through town on city and highway roads, I average about 0-2 BSM falses per hour which is really very good. I’m very happy with the R3’s filtering capabilities.

DFR7 costs $100 less

Uniden R3 purchase

Finally, the R3 is more expensive. The DFR7 normally retails for $299 but you can currently find it for a few bucks less.

The R3 retails for $399. That’s pretty incredible when you think it outperforms the Escort Redline which costs $550. It gives you longer range, better BSM filtering, also RDD immunity, plus all the benefits of the GPS functionality.. all for a lower price.

The only issue demand is really exciting supply and typically they come in in batches and sell out quickly. Often times there’s a waiting list. If there’s a waiting list going on, it’s recommended to hop on to make sure you can get one in the next batch. If they’re in stock and available, it’s generally recommended to take advantage of that fact.

Order a Uniden R3.

Finally, if you don’t need the GPS lockout functionality, you can get the Uniden R1 for just $299. (This is actually what the Redline comes against directly since the Redline also doesn’t come with a GPS chip.)

Order a Uniden R1.


I know in this article I’ve been focusing on the advantages of the R3 over the DFR7.

The DFR7 is still a great detector, don’t get me wrong. At under $300, it is a great bang for the buck, offering a ton of performance and capability for the money.

If you want to go for all out performance plus the additional features that the R3 offers, I think the additional step up in price is money well spent.

If an R3 fits your budget, I’d recommend getting one.

If not, I think you’d be happy with a DFR7 as well.

    Hi vortex thanks a lot for this article very usefull as always.

    I live in France.

    No Ka band here but K band only and laser.

    No MDRC at present.

    I have a DFR7 and a Genevo one S Black Edition.

    If you were in my situation what will you do?

    I don’t need GPS lockouts driving often out of the city of in the highway and RDC alerts of Uniden are not usefull for me because of it don’t alert for RDL in Europe.

    Would you change the DFR7 for the R1 or not?

    I would like to know your opinion.

    Thanks in advance.


    1. Sorry I can’t tell you. I know you have other options for international detectors and firmwares, you have different radar guns, and so on.

      Due to your laws, you’ll likely want to look into remote detectors too like the Stinger VIP.

      Laser is also heavily used there.

      Here’s an older discussion regarding France. https://www.rdforum.org/showthread.php?t=32724 Feel free to hop in and continue discussion there for more updated discussion.

    Hi Vortex,

    Based on your review, I took delivery of the DFR7 from Tom today. Love it, drove around for about an hour. Only picked up 1 false alarm. Since I live in Toronto my #1 priority of immune to RDD, good false alarm filtering with good range. I thought about the R3 however it does not have the MCRD feature.

    I anticipate up grading later this year can you alert us if they are including the MCRD feature in the R3?


    1. Congrats! I haven’t heard of any plans to add MRCD support to the Unidens.

    Hi Vortex,
    Thanks to the countless video and tremendous updated info you provide, I want to buy a Uniden R3 but to put in on my motorcycle. Can you recommend a proper waterproof case that will allow such install?
    Thanks a bunch,

    1. I’m not familiar with everything that motorcycle riders need. Take a look at this thread: https://www.rdforum.org/showthread.php?t=52205&highlight=motorcycle

    Hi Vortex,
    Thanks for your informational videos and reviews. I’m interested in getting a Uniden R3 and had a question of how well it performs when receiving BSM signal(s). For example if I’m behind a BSM broadcasting K band vehicle or if the vehicle I am driving has BSM, does the R3 stay quiet until your blasted with a cop using K or Ka band radar?

    In comparison I have been testing a Whister cr93 and more than 50% of the time I will get a FDSR alert (supposed to be for BSM only) when it is a real K band clocking me. In other words if I get hit with a real K or Ka band radar I do not get any new alert if FDSR is being displayed.

    If you covered it before, sorry I missed it.


    1. Well virtually every detector out there will false to some BSM’s. It’s an unavoidable fact of life if you have a detector with K band enabled. The Unidens are some of the better filtering detectors out there though.

        That is good to know. Do you know if Uniden gives you a new K alert if it already has picked up a BSM?

    I recently purchased the Uniden R3. The problem I am having is that there are many locations where there is no Red Light Camera notification. Some locations, no notifications in either direction of travel, others in only one direction. I have spoken to support at Uniden and the answer was that he will pass the problem along.

    I am using the latest updates 06.13.17.

    Is anyone else having this issue?

    Thanks Tim

    1. Every RLC database needs periodic updates. Things change and so no database will always be 100% accurate. Thanks for reporting it though! That’ll give them a chance to make updates as needed.

        The cameras have been in place for at least 2 or 3 years. And the notifications are only in one direction of travel. Uniden says the R3 is non directional.

    Uniden seems to be the Top Dog of detectors, but until they or someone else can find a way to filter out false alarms caused by manufacturer vehicles, I’m holding out.

    Hi Vortex, we in Fiji Islands love your utube videos. I need your advise on the best radar detector that works best against LTI 20/20 Truspeed which has got range coversge of 1200m and also with speed cameras mounted on highways.

    Appreciate your assistance…

    1. Fiji Islands hello! 😀 Can you get a laser jammer there? Radar detectors are really poor choices against laser. If you want a sensitive radar detector for laser detection, something like a V1 or Redline EX would be good, but keep in mind that they generally won’t alert until you’re being targeted.

    HI Vertex, uniden DFR9, Is this having laser jammer also in it?

    1. No radar detector has a laser jammer built in. They have laser detectors, but they’re almost useless in practice. You’ll need to pick up a laser jammer to pair with your radar detector.

    Am I reading the graph correctly, R3 has 3x the range of a DFR7 on Ka34.7 If so it’s a no contest for me..
