There you have it. That is the short list of the top performing windshield radar detectors.

In a nutshell, the V1 and the STi are designed primarily for highway driving and long road trips. The models listed in the second group are designed mainly for suburban and city driving since they feature GPS in order to filter out known false alert locations. Those false alerts are caused by either X band or K band microwave automatic door openers and by alarm systems which use radar motion sensors.

The V1 has front and rear antennas plus arrows to indicate where the radar source is located — front, back, or to the side. Yet the V1 is readily detected by the Spectre radar detector detector (RDD) which is used by police in VA and by the DSP in Texas to nab motorists who are using radar detectors. The STi, on the other hand, is completely immune to detection by the Spectre RDD or any other RDD since the STi does not emit any type of microwave radiation. In short, the STi truly is a stealth radar detector and its steath makes the STi worth its weight in gold.

I have extensively road tested both the V1 and the STi. Both perform very similarly in terms of overall performance, with the V1 having a very slight edge. Yet the STi’s stealth, combined with its superior quietness when used in cities or other suburban areas makes the STi the clear winner in my book. The STi, unlike the V1, is also extraordinarily easy to program in order to configure its settings to perfectly suit your needs. My one major caveat regarding the STi is that its built-in speaker isn’t very loud. But this issue is easily solved by installing the extremely loud amplified remote speaker which Beltronics includes with the STi. You can hear the remote speaker with the top down and with the radio blaring.

In short, the Beltronics STi Driver is my favorite windshield mount radar detector. It is so good that I use it all the time even though I also have the Escort 9500ci remote installed radar detector and laser shifter system installed in my car. I always operate one or the other radar detector in bar graph signal strength display mode with the other radar detector in radar frequency display mode. This way I not only know how strong a radar threat is, but also the specific nature of the radar threat. For example, 24.7 frequency Ka radar guns are relatively easy to detect, but 35.5 frequency Ka radar guns are harder to detect since these radar guns have very long and narrowly tapered radar antennas. You have to slow down immediately when detecting 35.5 Ka radar since most of the time there is no easy way to determine just how far away the 35.5 radar gun really is.

Finally, although the Beltronics STi Driver is my favorite windshield mount radar detector for my particular driving needs, it may not be the most ideally suited radar detector for you. For example, if most of your driving (or my driving) is suburban/city driving, then I would pick one of the radar detectors which I listed in the second group. On the other hand, if you are a road warrior who logs hundreds of interstate miles every month and if you frequently travel through VA or TX, then the STi Driver is your only real choice. Excluding these two states, then the V1 also is an excellent choice, and at that point it boils down to your own personal preferences as to what features between these two radar detectors which are most important to you.

If you buy a used STi, keep in mind that most likely it will not have any warranty. If you buy an STi from an unauthorized dealer, then it will have no warranty whatsoever. If you buy a used STi, then you should be willing to send it to Beltronics and have it flashed with their latest firmware which addresses several issues and which improves overall performance. Yes, there will be a fee for this service, but on the other hand, a used STi with the latest firmware flash will perform exactly like a brand new STi. Something to think about.

So, there you have it! I always try to cut to the chase and write unbiased product reviews.

Very robust construction, “dark mode” feature prevents display from becoming a beacon to other drivers who want to tailgate you thinking you will save them from a ticket (Not to mention attracting unwanted law-enforcement attention for the same reason).

It’s not cheap but compared to the cheap units, this thing far outreaches them and provides useful features instead of deceptive fluff. Go with the best. You will not regret it!
