Hello World!

I am one month old, new MB EQS AMG owner - and as you see on topic, I'd like get some ideas how to use radar detector on EQS because otherwise this car will be too hard to my driving license!
I know, I know, "use co-driver helpers, keep speed limiter active, don't drive too fast, don't be stupid.." - but, I don't want to be part of woke-world, I want drive my EQS like old'school cars will be driven - and because this car is too quiet and too comfort, it will be hard to keep speed always under speed limit.

I have +12v outcome near glowbox and my radar detector works fine with that but detector don't get radar signals as easily as my earlier cars. So help me, is there good spot somewhere? I even thought that I open front hood and I will put my detector there with bluetooth adapter and connect that bluetooth-loudspeaker inside car but this sounds,.. not so EQS-style solution, so.. Any good ideas?

Thanks!

In your user manual, check under the section "Area permeable to radio waves on the windshield".
There are two spots - one in center at the bottom of the windshield, the second next to mirror at the top on the right side.

SEE ABOVE, BUT CAUTION!
There are numerous posts here about these "windows.', that indicated that EZ-PASS RECEIVERS STRUGGLE TO WORK WHEN MOUNTED IN THESE AREAS. I'D SUSPECT THE SAME MIGHT APPLY WITH A RADAR UNIT.

Find the"window" in the bottom center of the winshield. Your range should be fine. Works for my escort redline 360.

If both 'windows' work, putting it to the upper position (ie next to mirror) should give a better range coverage for the detector.

True, but you would have to run the cable around the entire windshield or dangle the coiled cable from there to the hidden 12v under the dash. Even at the bottom of the dash Im getting many miles detection on Ka. The redlines detection is ridiculous. Finally, I have a transponder there.

Not sure if I understand your detector range coverage statement. For a narrow RADAR Gun beam angle of say 9-degrees, at a Range of 1000 feet the beam width is about 160 feet. How do you get better range coverage from the Detector positioned by the mirror as opposed to a position lower on the windshield? Detector signal is the same with a loss proportional to 1/R^2. If the Detector was way off-axis the signal would be REDUCED by a cosine term.

Edit: Guess you might get better coverage higher up in windshield for the extreme cases of mountains, hills, or dips in the Road...maybe.

I can goto sleep now...lol

You might be thinking horizontally (ie azimuth) while I am thinking vertically (ie elevation)

I'm thinking both horizontal and elevation if the Police Radar has a circular antenna. Beam width is a total of 9-degrees (+4.5, -4.5) at the edges of the beam, detection is down to 71% level relative to the beam's center which are the -3dB points. Again at a Range of 1000 feet the circular beam profile for the center lobe is 160 feet across (+80, -80 az-el). If the radar detector position on the windshield is separated by say 2-3 feet inside the car the relative signal degradation is in the noise. In extreme cases because of hills and other obstructions in the road the radar beam will be masked.

For Laser Radar the beam has a much smaller divergence angle on the order of 1.5 milliradians. This is why the Police point the laser radar gun at the front license plate. In this case you would want the laser detector inside the car as low as possible on the windshield. Laser radar guns are used at much shorter ranges so more than likely by the time your detector is alerted you will have already have gotten a ticket if you were speeding.

When I travel cross country in addition to my Radar/Laser detector I use Waze. Used to carry a Uniden Police Bearcat 800 Scanner programmed for whatever State I was traveling in the old days. Bearcat also monitored the CB band that the Truckers used to alert where the Police were at.

A higher position is always advantageous on hilly terrain. But we are talking fractions of a second if the radar is near. BTW narrow band radar is a misnomer, its still radar and will spread very significantly compared to lidar not to mention it will bounce off anything solid in its path... The new detectors are so sensitive that range in the most important Ka band is really not an issue at all. The main issue that differentiates detectors today is filtering.

So.. Next question will be: How on earth I can hide wires as smooth as they need to be on EQS-quality car.. Damn..

Motonet

HAA! One new solution, maybe?

Bluetooth radar detector! What are you thinking about if I install this kind of detector under front hood and only use bluetooth inside cabin? I'd like this idea, only minor problem is that I don't have android phone.. :/

precusely.
