Uniden DFR6 VS DFR7

02nd Feb,2022

Good radar detectors are a dime a dozen and therein lies the problem. There are just so many of them that are good at what they do, that it can be difficult to find out which is best suited to your needs. 

The aim of this article is to see what Uniden has to offer as we pit two of its models together in this Uniden DFR6 vs DFR7 comparison. We start first, with their advantages.

Features of Both Radar Detectors

Here are some features of the Uniden DFR6 and DFR7 radar detectors and how they compare. 


The DFR7 makes use of the lauded GPS capability in numerous ways. The DFR6 lacks this feature, which makes GPS the major difference that sets these two devices apart. 

The DFR7 has GPS lockouts which enables the radar detector to identify a false alert it passes on a regular basis. The radar detector records this and automatically mutes the signal if you pass it in the future. 

That being said, it does go a step further. As this lockout could create a blind spot, it actively searches that location and if a new signal comes up, the driver is quickly alerted.

The DFR7 also benefits from low-speed muting which is helpful when you are driving around the city. It wouldn’t be a surprise if more people made use of this feature than lockouts. 

For instance, if you are driving in town at a low speed, perhaps stopped at a light or in traffic, the DFR7 automatically mutes itself. All you have to do is choose a speed threshold and the detector does not make any noise.

Red Light Camera Alerts

The DFR7 excels at this as it is able to alert you of any red light cameras in the vicinity as well as speed cameras [1].

You don’t have to worry about missing a new installation as long as you update your radar detector’s firmware. The drawback to this is that it does not have Wi-Fi capability like other radar detectors out there, so you will have to connect it to your computer.

The DFR6 completely lacks this feature and while it doesn’t make sense that Uniden would release a radar detector without this feature, you have to understand that the DFR6 is the predecessor of the DFR7.

The DFR7 is supposed to be everything the DFR6 is and more.

False Alert Filtering

The DFR7 has numerous tools to deal with false alerts.

One of the banes of radar detectors has to be the new blind spot monitoring systems or BSMs on vehicles which make use of the K band.

While most radar detectors struggle with this, both the DFR6 and the DFR7 are capable of filtering them out. The DFR6 has a great false alert filter and the DFR7 builds on that to create one of the best BSM filters on a radar detector on the market today.

While both devices are good at false alert filtering, the DFR7 gets the edge in this and that is due to its GPS capabilities. It is able to utilize GPS lockout filtering stationary false alerts.


One of the marks of a good radar detector is the promptness of its alerts. When you have sufficient time between the warning and approaching the signal, you are able to adjust your speed and driving.

That said, the actual detection depends on certain factors. For instance, flat, straight roads are perfect for longer detection than curvy, tree-filled, hilly terrain. Additionally, there are some radar detectors that perform way better on certain frequencies and bands than others.

Given that they are made by the same company and in the same series range, both the DFR6 and the DFR7 have long range detection. They tend to perform at their very best when using the Ka band at 34.7. Thankfully, this happens to be the most widespread radar frequency in America. 

Both devices perform quite well, as they are able to even come close to the king of long range detection which is the Escort Redline. They seamlessly beat certain radar detectors in a higher price range as well.

Reading that, you might think both the DFR6 and the DFR7 are faultless. However, they both stumble when it comes to Ka frequencies such as 35.5 and 33.8. This isn’t a deal breaker if you do not see too many of these signals, however, for the price you pay for them, you would expect a much better performance. 

If you happen to live in an area that does see these frequencies a lot, you are better off selecting the Uniden R3, as it provides a much better performance on every radar frequency. 

However, if you are restrained by budget or just prefer the DFR series, you should definitely go for the DFR7 as it offers a much better performance than the DFR6 on the Ka bands.

Conclusion: Uniden DFR6 or DFR7

Both detectors are excellent in their performance ratings. 

If you spend most of your time driving on the highway or are mostly venturing into new cities and town, you can do without the low-speed muting and GPS auto lockout that the DFR7 gives you, then the cheaper DFR6 is for you.

However, if you want to have GPS functionality when driving around your city, then the DFR7 is for you.
