Okay, a couple of things. First of all, many cars, mine included (Porsche), allow the "accessories" which in my car includes the lighter socket, to remain on for around 30 minutes after the ignition is turned off. My guess is that's what happening in your case.

On the subject of false laser alerts, I drive in sunny CA and have yet to receive even one laser alert after two weeks of driving with the V1Gen2. Based on a couple of reports on this forum of false laser alerts I was thinking maybe mine wasn't working so I checked it with my golf laser rangefinder and voila it worked perfectly both front and from the rear. So maybe this false alerting is a "bug" in some of the early units??
The position of my vent mounted cell phone could set off laser alerts on my Gen 1. Angling my phone away solved the problem.
Installing ALP's let me turn off laser completely.

I had a Honda CRV punch through two days ago. this was in my neighborhood so I was tracking things. It was quiet and punched through at around 200 feet for a few seconds and then quiet for 1/4 mile and then went berserk about 40 feet away as I was pulling into my driveway- it was next door. Bogey counter shot up to around 5 for a few seconds and went quiet again.

it does generally filter Hondas with some minor punch throughs
Mine gets here on Tuesday. One of my first tests will be Hondas, since I own one. If things go well I won't need a Uniden with K block for road trips.

I ran the G1 and the G2 side by side for 2,400 miles of mostly interstate highway driving. No signs of interference or cross talk. The G1 was wayyyy quiter with respect to BSM alerting and had better range on KA. Here are my results:

I think you had a typo, the G2 was way quieter than the G1 for BSM.

I can tell you that my V1G2 in combination with JBV1 is far more quiet than my Escort Max 3 (even with the suggested settings from Vortex to make it less chatty).

You are correct. My error. The G2 is wayyyy quieter.
Thank you.
I'd like to see anyone else provide similar pictures with a working detector lol.

☝️ No GPS. Default setting. No app. Heavy amount of Chicago traffic and plenty of K pollution to filter!

Note: The V1G2 can totally classify the Mazda CX-5 signal! It will however let the signal burn through, Mike Valentine mentioned such safety measures in his interview, when the signal comes in at a 3-4 of 6 strength. Typically that happens if you keep less than a car gap between you and the CX-5, and some other things.

Some earlier R1/R3 FW could filter the CX-5, but probably not intentionally lol. Because later FW dropped that capability 🤔.

I mean ya can't make everyone happy, but this is next gen performance right here!

Mine arrived Tuesday. I have had a much different experience. I want to wait for a few solid LEO alerts before posting a thread of my own, but so far I find it more sensitive to RADAR but quieter while driving. I can run Gen 2 in Logic or All Bogeys and have a quieter ride than Gen 1 in Advanced Logic. Interesting.

I've had my V1G2 for over 50,000 miles of driving and I agree with your assessment. Overall, it's quieter in nearly every situation and every mode, but the ability to alert actual threats is by far better than my old V1, and it's better than my R7 and R3 in both way... actually far quieter and noticeably more sensitive.

You would need to run the units as independent, and them you can run them together. Need to learn the tools and know if one will interfere with that other, then report. Welcome to the world of RF/leaky, and other things about running more than one. There is said a spacing of units, but times that has to be thrown out, as a leaky unit will silence one or overly report another. Put an old Whistler into programming, a Ka report off the charts can happen.. why, good question.
I saw this today while running my Gen 1 and Gen 2 together. While neither caused a false on the other, Gen 2 had a delayed response vs its solo runs. I'm glad I noticed this before making any statements on performance of G1 over G2.

I think you're confusing "classifying" with filtering. The V1G2 is certainly better at filtering Mazdas than the V1G1, but I don't think it has any way of classifying it as such.

With the V1G1, I would get a brief, strong 24.12x false from the rear antenna when a Mazda would pass in the opposite direction, and the high initial signal strength would sometimes make it difficult to filter out even with JBV1. With the V1G2, I no longer see this brief strong alert, but instead get a 1-2 bar alert at close range. I typically run Logic mode (little L), and JBV1 handles this no problem. No audible alert, detector stays dark, and I get a muted alert overlay from JBV1. In Advanced Logic mode like you're running above I would expect it to be even quieter, and I'm actually surprised it punches through at all.

The only thing better about my V1G1 than my V1G2 was the ramp against I/O and Q/T shots. The range and off axis between the two of them is not in the same world, at least on any Ka band signal. The V1G2 murdered my V1G1! If and when the ramp and ghosting issues get fixed, this will be one bad @ss detector, even though it already is the best one I've ever run!

I bought an R7 with a 90 day return deal through Amazon and ran that with JBV1 standalone while waiting for my V1 G2. Now that I have the G2 I love the connected features and smaller size over the R7, which I was otherwise pretty happy with. The G2 has had one Laser and a couple of probable Ka falses, but otherwise it’s been really quiet. Impressive!

On the Mazda topic:
I hadn't been focusing on this for a while; but a few days ago I was alone on a road with a CX-5 ahead of me.
On v4.1018 I had experienced brief initial alerts from Mazdas and was expecting another.

I'm on v4.1019 now. I kept getting closer and the Gen2 was silent. I was just about convinced that it didn't have BSMs at all and then as I passed it the indicator on his mirror lit up.

This is only one experience, but this observation suggests that they've improved Mazda BSM rejection in v4.1019. :)

V4.1018 was much better with Mazda than v3.8945 of course.
Valentine has said that they have a lot of room for further improvements and I suspect this only a small improvement. :)

I'm not confused, but thank you! I've provided info elsewhere for those interested to read. The baseline technique is not new outside of this industry, as many have oddly enough.. tried making fun of. If you have an alternative opinion I'd be interested to see a detailed breakdown as to why, while referencing the general design of the V1G2.

I'm all eyes ☝️

Anyway, owning a second gen CX-5 has been fun! Those vehicles really spray the K out!

Typical behavior for me: the signal is tracked, sometimes a far out alert situation occurs. Normally a car-length-distance+ works well, any closer and a 3-4 punch through occurs. To me this is burn through safety logic. Other lanes aren't a problem, and neither is driving my own second gen CX-5... finally a RD that can do it!

It can do this in A and l against the CX-5, but obviously L is just great with keeping things all around quiet.

What are you talking about? If the detector was able to "classify" the signal as coming from a CX-5, why would it ever alert to it? There should be no such thing as "burn through safety logic", as if it were "classifying" the signal the confidence in the ID should only increase.

I suspect the improved false rejection we've seen from the V1G2 is due to DSP algorithms running on the FPGA, where stronger signals could be expected to overwhelm the filtering and lead to PTs at close range. Reviewing my JBV1 logs from the past week, I don't see any Mazda 24.12x BSM falses that registered above a signal strength of 2, while several Honda 24.20x falses registered a max signal strength of 3. Now that the V1G2 has the ability to receive OTA updates, I'm really looking forward to see how far they can push this platform with continued firmware tweaks!

@InsipidMonkey

This is just your opinion though... to be completely honest 👇

[What are you talking about? If the detector was able to "classify" the signal as coming from a CX-5, why would it ever alert to it?]

***What's your criteria for classification?***

And are you telling me there's no need for safety based logic, or room to discuss this on here?

This goes against Murphy's Law (VR loves) and Mike's own comments on burn-through.

I'm one of the few that posts information that parallels with VRs HPI patent to help further understanding which are not just my own words; would you mind doing so to help others further see your opinion?

And maybe another thread dictated to this would be more appropriate? IDK, just a suggestion. We can publicly exchange information to help convey our thoughts in a more appropriate manner that way!

That said, if we do not then I will simply agree to disagree. I acknowledge we all have our opinions.
