I would like to install my V1 radar/laser detector in the location shown in this picture. There are a few problems with this, due to that "shade" that covers the center part of the windshield...

1. The shade will make laser detection from the front impossible
2. Depending on what material is used in on the shade film (metallic film? plastic?), radar detector performance may be adversely impacted too.
3. The slight texture of the shade film may result in the suction cup mount losing its grip over time/bumpy roads.



Question: Is it possible to safely remove a rectangular section of the shade material from the windshield under the area I want to mount the radar detector?

Looks like the shade is some sort of film coating that I might be able to carefully cut with a razor blade and peel off. Before I take a gamble with that I thought it best to see if anyone else has tried this before.

I can't answer your question, and I apologize if you have already considered this, but have you checked out the radar detector mounts that clamp on to the stem of your mirror and suspend the detector beneath the mirror?

For example:

I have my Escort Redline mounted behind that "shade" above the RVM too. I modified the suction cup mount and use 3M Dual Lock fasteners to affix the mount to the windshield and make it easy to remove/replace if needed.

A dab of adhesive on the suction cups would work too, though it would be more "permanent" than a normal suction cup installation.

Radar performance is unaffected, and for laser I wouldn't trust a radar detector to save you from laser anyway. Usually laser alerts on a detector are a ticket notifier. The V1 is so sensitive that it should detect laser through the black dots anyway.

I had not looked into that, thanks! Looks like a reasonable compromise that solves my problem.

Since posting I've had a chance to road test it as shown in the pictures, so far the standard V1 suction cups are holding up just fine. Before installing it, I thoroughly cleaned both the window and the suction cups. I agree that radar performance is not noticeably effected. My initial concern was that the black dots were a metallic film, which would kibosh radar performance - apparently they are just a plastic that is practically transparent to radar. I'm seeing the same K & Ka band speed traps and false detection sites (shopping malls mainly) at the same detection ranges I usually see them.

As for laser detection, I found that the opaque black dots definitely do degrade performance. My test for that is to drive right behind a GM SUV such as a Caddy Escalade, GMC Denali or Chevy equivalent at a traffic light. When they hit the brakes, the LED hi-mount brake lights on those vehicles ALWAYS cause my V1 to "false" a laser detection. Mounted as shown in the picture, there's no laser detection in that scenario. Pull it off the mount and manually locate it just below the black dots, (while SUV ahead is still on the brakes) and my V1 goes into full laser alert.

The GM brakelight test isn't the most accurate indication of laser performance. Even without the "dots" you have to be right behind the light. The V1 should detect real laser. See if you still get falses when Infinitis, Volvos and Mazdas with the smart city brake system drive toward you.

If laser is a real threat where you are, you need to look into real laser countermeasures. Go to a countermeasure forum such as https://www.rdforum.org/forum.php for more info. I'm a regular participant over there.

What trim Mazda3 do you have? Does it have the blind spot monitors? Do you find they interfere with the V1 at all, or not? I picked the iSport trim mainly to avoid those (as well as to keep my payments within my meager budget), but I miss out on a lot of other things too.

I've got a 3S GT hatchback, but I passed on the tech package that includes the radar adaptive cruise control & other nanny options that come with it. The car does have the blind spot monitoring and rear cross traffic monitoring though as standard, which might use radar sensors. I'm not seeing any interference with my V1.

I'm aware of the issues with the GM brake light test, so I enlisted my neighbor who has a Denali to help out with a controlled test in the driveway. I pulled up to his rear bumper and had him keep his brake pedal depressed. Then I moved the V1 from where it mounted behind the dots to just below them; result was a constant laser alert when it was below the dots, and it would drop the alarm as soon as I moved it above the dots.

The Infiniti's, Volvo's, etc. with the radar cruise/smart brake support nannies trigger a V1 laser alert too, but those alerts are normally from the rear (6 o' clock arrow), and thus the dots on the front windshield wouldn't impact that.

Thought I'd post an update since I got my mount and power cable to jack into my rearview mirror today.

TLDR I'm pretty happy with it, so far, and would recommend it as a good value vs alternatives.

I haven't driven much to see how it holds up but so far so good. The cable had robust power pins that are a tight fit but I wasn't worried about breaking them. I couldn't get them to fit all the way in, but they were snug and made good contact for power.

The mount itself was sort of a pain to mount but not bad, just annoying as anything when working in a small space is. I wrapped the location on my mirror that I wanted to mount it to with a bit of black electrical tape as I've heard complains about this mount scratching the pedestal. Once I assembled the mount and tightened it up it feels sturdy and my radar detector popped right in. Tied off the cable with a zip tie (included) and looks really clean.

I also had no problems with the GPS on my Escort getting a signal.
