Posting this in general b/c I feel no one will read it in Cobra and figure it'll get moved if I post it in Escort....

So I ended up with a pair of Cobra Dual Pro 360s (after returning a Road Scout) and put one in my wife's car to replace her ancient and noisy Bel GX-65. I love mine. I have been a 7 year V1 owner and the range is as good or better, off-axis is great, iRadar/Escort Live is handy, plus the detector is much quieter......for me.

So, I drive a base model 2018 VW GTI. very minimal tech. Wife drives a top o' the line 2018 VW Atlas SEL Premium 4Motion. BSM, collision avoidance, etc, etc, etc. I slapped the DP360 on her windshield and thought she would love me forever for quieting down her drive. Instead, she hates it with a passion. Now, I used this detector first for about a week in my car and it gave me NO problems. My commute takes me out of the city onto the interstate for an hour to a rural setting. Her morning slog is all city. But still, I figured if she ran Auto Low K she'd be fine. And she is...on K.

Ka is driving her nuts. As soon as she leaves our neighborhood, she is getting both seemingly real 33.8 (there is a deputy that lives in the area) and random falses 34.5, 33.5, and a few more for the first few miles of her drive from our house. Now, I make the first mile of this myself, about 30 minutes early with an identical detector and get none of this. Traffic is definitely heavier when she leaves, though. I have driven her car at other times of day with this detector and not had this issue, even in town so I don't think it's just urban sensitivity or the detector being set off by the car. The only time I can definitely say it's the CAR is she will get a Ka false in the garage. I forget the frequency but it's not a police band.

She's called me several times now to make me listen to the detector and yep, I can hear it going off to Ka. She wants her GX-65 back because she "at least knows to tune out all the K alerts."

I've been scrolling through the Escort forum and see there were issues with the 360c and Ka falsing but not so much with the plain 360 that the Dual Pro 360 is based on. I guess my next step is to segment. I have updated to the most recent firmware offered and noticed no difference. @CobraRadar

There have been a few folks here that had trouble with ka falsing on the dual pro I believe and had to send it back. I believe specifically it was the rear arrow on 33.5/33.6.

I'd try to send it back for service. At least reach out to see what they say.

Can you try swapping the detectors back into the other VW again and see if the issues continues with swap (does your alert to all those things in her vehicle and does hers not alert in yours)?

My GT360 had those odd rear Ka alerts on both an Audi and my wifes Atlas (SEL, same as yours) , mostly in the 33.5- 33.8 range and it was the detector. My wife runs the R7 on a daily basis in her Atlas and it has not alerted to anything related to the car AFAIK, she likes how it has only been alerting her to Leos or the Ka speed signs we drive by - she had the R3 previously in the Atlas and like the arrows and bigger screen.

You could also try segmenting the detector if you have not already. Only if you know she will not encounter any valid radar in those segments.

I would try to swap it first and then send back if the issue continues.

I agree, swap detectors and then try swapping cars. You'll have narrowed it down then.

No, like I said, I drove with that detector in my car for at least a week before I put it in hers and it was pretty much dead silent until a real encounter. And when I have driven her car I don't get all these falses. But I don't drive her morning commute. Heck, maybe it had the sleeping issue as well and I didn't realize it lol.

I have one more week in my return window so I guess better safe than sorry. I had bought an R3 to compare against. I guess I'll put that in for now. But she is going to miss her Beltronics tones.

Thanks for the insight, guys. Didn't realize this was a big issue. Hasn't been for me with the one in my car. Ironically I had a rear alert for miles today but it was a legit 34.7

I believe this was the first year/model with WiFi. Having a RD in close proximity to WiFi (especially 5GHz WiFi) can cause sporadic Ka falses due to harmonics. Can you try repositioning the detector or maybe test it out running low on the dash to see if the falses go away?

Otherwise, it seems Ka falses are an issue with the 360c platform, and the detector should be sent in for service.

It could have gone bad after you ran it in your vehicle for a week, mine seem to work fine for a few months before the rear Ka items started. That is why we are suggesting you swap them again before sending back.

Also, have you updated to the latest firmware?

The 2018 SELs were designed to be an in car WLAN network (no separate sim card like the audis until the 2020 models). It just rebroadcasts a signal from your phone, businesses, mifi etc. Some of the 2018s sold in the US were not even enabled for this feature from the factory, and you have to spend some time to set it up.

Ours has it, but is not enabled as we just use a Mifi to travel and connect devices directly to, so if his is it could be part of the issue.

Yep, mentioned already I updated the firmware in both detectors. I guess I can do factory resets again in both. Regarding wifi, I enabled whatever the hot spot or wifi is because when I bought the car, I misunderstood it as having a real hot spot and spent about a month trying to figure out if it really did or not. So maybe it is. But as I have mentioned and should elaborate on, I have driven her car multiple times with this detector in it. I have never seen it act this way. But she's complained to me about it falsing on Ka multple times, called me several times and had me on the phone where I could hear the distinct Ka tones. So, I was wondering if it could be just heavier concentration of BSMs or something? Or could it be her cell phone? New iPhone 11? Or just known random Escort issue?

A recent update added MRCD detection I believe. If this is turned on you can get increased false KA alerts. You might check the setting to make sure it's off.

Yeah I saw that and I THINK it's off but I will definitely have to go and make sure.

I bought my wife the Radenso Pro M. You might look into it. My wife did not complain about her Uniden R3 but I could hear it on calls, she never marked anything but just ignored it. So, we had to make a switch. It’s so much quieter now.

Well, shes never had a problem with Ka falses before with her old GX-65 and that's what's got her pissed. Shes fine w K falses. Shes run a detector as long as I have and is pretty savvy with deciphering true alerts from falses. Shes a pretty terrible driver, lol. So glad I got her into the Atlas and out of her Yukon XL. I was convinced she was going to kill someone in that car. She grenaded the transmission at about 110k miles so I used that as a good excuse. At any rate, when she gets in, I'll hook up my phone so I can check the settings and go from there.

Update, I checked her firmware and for some reason, the firmware update I did to it didnt take. So, I redid the update and verified it was on there. So I'll let her run that Monday morning and see if that fixes it. If not, back she goes.

I segmented my Max360c due to strange Ka band false alarms I would often get just within the first 2-5 minutes of powering on the detector. (This happened at different locations) Those false alarms would then go away until the next power cycle. It is very strange.

Hopefully the firmware update will fix this issue so you don’t have to send it back.

When I sent my Max360c in for service, I mentioned this Ka false issue (out of normal Ka frequencies like 34.580 or 33.640), but it wasn’t the main issue I sent it back. Escort appears to have fixed all of the problems I was experiencing except this one with the “strange”
occasional Ka false alarms, so I just segmented my detector to fix it on my own. Good luck and keep us posted on what happens with this firmware update.

Yeah, I am going out of town on tuesday and she has until feb 1 to return it. I told her to drive around mon and let me know if it does it again. But I'm thinking I still may just segment it if it does. Because the filtering is otherwise incredibly good while giving excellent range.

Lots of reports of Ka falsing on the Escort radar forum too. I haven't seen any reports of Ka falsing after being repaired, so they'll probably be able to fix it. Since you're getting close to the return period, it may be better to just return it and get another one though. Good luck!
