Emergency vehicle sire whooping noise in car?
Ok I have resisted asking this question because it to me is bizarre and I can barely describe it and have had no luck Google searching the entire internuts.
3 times since I bought the car, I have been driving down the road at normal speed and all 3 times it has been in congested town areas here in SF Bay area. Suddenly inside the car, I will get this insane klaxon/siren type blast that lasts for about a minute. All 3 times it has come out of nowhere and has scared the hell out of me. There is a voice speaking and I THINK it is giving a warning about an "emergency services vehicle" in the area. It is really hard to hear the voice and it takes about 5 seconds to realize it isn't FBI HRT about to snag me for some reason. Twice it happened when I could see an ambulance and once when there was a deputy in Woodside on the side of the road doing paperwork (not a speed trap)
Is this a Mercedes thing or maybe the custom radar detector/laser scrambler or whatever they are called? I keep mine turned off for the most part.
Finally I did briefly read about something in Europe where some cars have some ability to monitor for emergency vehicle communications- It didn't seem to apply to me so I didn't read too much of it. It is really pretty insane and distracting it is so loud it sounds like an ambulance is inside the car.
Any ideas? I'll see if I can find the write up about emergency vehicles in Europe UK
I am wondering if there is something like this installed or if Mercedes has it and I just haven't seen it while reading the manual.

This is a really odd one - has to be some other device than what’s built into the car - do you have a radar detector, aftermarket car alarm, dash cam, aftermarket radio/head unit, or some app on your phone that does this? Very curious to know what this ends up being.

It's an alert from your phone. Our state has decided to crash everyone's mobile phones and let us know when there is an Amber alert or something else. How kind of them.
You should be able to turn the alerts off on your phone. Somewhere. Mr. Google can help, if necessary.
I was surprised the first time this happened to me. I made sure the first time was the last time.

Thanks I thought it was amber alerts too and I checked there was nothing on the phone nor was the phone going off. Weird right? The 2 times with the ambulances both were doing the lights and sirens and the alert came before I could actually see them in traffic.
Maybe I angered someone and they decide to give me random moments of terror in my car

Try to turn your phone's alerts off and see if that helps.
Can't hurt!

I do there is a custom radar/laser detector and laser dazzler (not sure what those are called) installed. I believe it is K40 I need to root around and take a look and see what is installed. I also recently had a Blackvue DR900X with battery backup installed. It can't be the Blackvue as that was just done this weekend.
It is really weird it is literally a very loud whoop whoop tone (a little different than amber alert) I'll tried to hear exactly what it is saying. I do know it does mention emergency vehicles.

I just checked it was already off and remembered had turned it off years ago. However, emergency gov't alerts was still on as well as Public Safety Alerts.
I am guessing it is the public safety alerts and the Emergency broadcast alerts. So I turned them all off see if it happens again.

So yet another brain-dead user interface (among sooooo many, these days) ... deliver, what could be, a life-critical alert (e.g., a tsunami) using a mechanism that may show only part of it (i.e., on a locked-phone's screen) and/or may appear to "go away" when you touch the message to read it (which may be dependent upon your setup) ... making it "almost useful" to so many people. <end of rant>

I think you may have solved it!

Thank you again! And thanks to others who pitched in. I do hope it works (I think it will) because when that noise comes for like 2-3 seconds. It is pretty startling. I'd rather a grenade go off nearby

It's the loudest sound I've ever heard on my iPhone.I didn't think it was capable of that decibel range. And if it is coming through your speaker system -- yikes!

So it isn't the EBS or Amber it happened again today except it was a whoop whoop whoop then a woman's voice said something I couldn't hear. I had stereo up (not blaring) this was quicker than the other 3 same alert signal. The difference this time was there were no emergency vehicles in the area. The other 3 times it was 2 times and ambulance and a 3rd time it was a cop who was pulling out with sirens going as he had got a speeder going in the other direction.
1. I hate that it just comes out of nowhere and I have no idea what is going on
2. I hate that so far it has scared the mess out of me and makes me screech like a 3rd grader in a haunted house.
3. My biggest fear is it will happen in front of my partner and she will hear me squeak and I'll have to live with her never looking at me the same way again. I mean what attractive 37 yr old woman wants a semi well groomed Yeti, that shrieks-farts when he gets scared?
