Help hardwiring Radar Detector for 2020 Sprinter

I didn’t know anyone used those anymore. There have been write ups but not necessarily for a radar detector. Most likely not a 2020 but the process is the same. Not the easiest way but tap into the builders connection point under the drivers seat and route the wires where you want them. Post 2 of the following link shows the connection in previous versions But I think this hasn’t changed for 2020 or the new versions. That is what that connection is for but others have tapped into power outlets if it fused for what you need.

The only recommended location I am aware is under the driver seat. I'm sure you could tap into something closer but that's not recommended by the manufacturer, and for good reason. Start messing with electro mojo.

I have a buddy that's into the radar gadget deal.
My idea is better, cheaper, safer. I don't speed, and when I do, I prefer Mountain Dew.

Hey guys, thanks for the help. I am well into the project. The wiring isn't too tough actually and Yes I'm tapping into the fuzes under the driver's seat.

Cheers!

Hey, share your experience, do those radar gizmos really work? And what brand are you using so I can check it out on YouTube.

Yes, they absolutely work. I got a ticket ~5 years ago in a Prius of all things. I was coasting down a mountain road in Tahoe and a cop was waiting there to keep his ticket quota up. I live in CA and the ticket was North of $500 which is ~the cost of a good radar detector, which helped me justify the purchase.

Long story, not so short, I have had a radar detector ever since. It has saved my bacon countless times. It's not a function of speeding purposefully by the way. All it takes is rolling into a changing speed zone where a cop is waiting to write you a ticket because you didn't reacted soon enough to slow down in time. Think driving into small town USA from a highway that goes from 65 mph to 20 mph and you spent an extra 30 secs at 30 mph.

I have a ESCORT MAX 360. It is not the latest model. I bought it used off of Amazon as they are very expensive.

My van has a DIN slot above the overhead center console. Probably for a CB radio or similar device. There is constant 12v, switched 12v, ground, and illumination wired to it with very thin gauge wires to a 4 pin connector. I connected my V1 to this via a wire tap. I wonder if you don't have the overhead DIN if the wiring is still there.

Also, there is constant and switched power under the passenger side toolbox in the fuse area.

Bob, are you thinking of breaking speed laws? I'm shocked!

One of my specialities in the USAF was electronic warfare, the use of the electromagnetic spectrum to attack and defend. So it was second nature for me to run a radar detector for many years. There are a range of strategies and tactics to be used with the detector based on the frequency used (which determine the ranges), stationary or moving and the topography. All of these are based on the idea that radar energy bounces around and you get warning based on some other guy getting irradiated. If you are in the main beam he has already got you.

However, with the increased use of laser speed sensing, there isn't a detector in the world that will provide you with warning for those devices that is meaningful.

In my older age and with increased use of lasers and the fact that radar detectors are illegal in VA (my current state) I no longer run them and don't feel a need to do so. I might exceed the limit by a little, but always obey the reduced limits going into a town or congested area, still applying tactical approaches to avoid unnecessary engagements with excitable guys with guns.

Mike, my understanding as well.

I just putt along at 60-65. Really doesn't make any sense to go faster cause the bulk fuel consumption is to overcome wind resistance.
Survival rates diminish considerably as well.

But that's that's the beauty of America, do whatever you want as long as you're not pooping in somebody else's punch bowl.

Did you purchase the mate to the plug in the din slot?

I used one of these and then guided the wire along the door rubber seal and then pulled the speaker and driver shelfs off the dash and had the wire come out onto of the phone storage box.


Now if I could just figure out which one of the circuits is switched I'd be set. I've tried several with no luck. Even after tapping into circuits that would presumabley turn off with the ignition (rear window heater, etc.) still keep the radar detector powered after the van is shut off.

I find google maps warns about speed traps pretty effectively. Obviously someone someone else has to have punched it in first but majority of speed traps I come across google warns me about. I usually drive 5 mph above the limit so it's not something I am very worried about.

You are out of the loop for too long. THe current radar detectors are so sensitive that they can pick up police radar from more than a mile out. I didn't use it for 10+ years, I am shocked at the advances they made.

I just picked up my sprinter and sold my M4. One of the first things I wanted to do is see if I can move part of my blendmount https://blendmount.com/quick_fit_guide (they consist of a mirror and a detector mount) over to the sprinter (lower portion that attaches to my Escort - magnetic mount radar detector). On the blendmount website, they list a kit for a 19-20 sprinter, however, the picture of the mirror does not match mine. For the past couple of days, I have been working with blendmount to see if they have a mirror clamp that will work. I took a bunch of pictures and caliper measurements and they have now recommended a mount that should hopefully work. It is being shipped to me today, however, I will be out of town for a couple of weeks, so I won't have a chance to test fit it. I plan on tapping power using a mirror tap.

You may have confused what I said about LASER detectors with what I said about RADAR detectors.

The laws of physics haven't changed in this area. I could detect radar signals a little over 200 NM, i.e LOS at the horizon, with the right equipment. I could also detect police radar miles away, using commercially available detectors - all depends on the topography, frequency, signal strength, tactics, etc especially in wide open areas away from cities.

If you are in the main beam and far away, the cop is getting lots of other energy returned to the receiver - you are in the grass (below noise floor) and would get warning. If you receiving reflected energy, maybe from the main beam or side lobe energy, the cop is getting a return in the main beam and your speed is not even computed. Cops and radar manufacturers have been getting smarter about instant on, but you can still get warning based on someone else being irradiated.

Because lasers are coherent (have no side lobes) and reflections don't splash all over the place you have a tiny, tiny chance of being in the beam and not getting your speed computed.

That’s how radar detectors really work, by picking up other people signals and give you ample time to slow down. The longer the range, the better, but I think it is getting to a point where the filter is what makes a radar detector $150 vs $450. The cheap ones are noisy.
