Not being able to find a good source for the topic, I will start this off with what I remember from someone talking his way through set-up in his CX-5.
This is becoming more relevant as Car and Driver magazine just listed CX-5 as one of it's Ten Best list.

Firmware 135.
I believe a good place to start, and reduce by 10% as needed until quiet:
K Narrow
Advanced K 50-70% start at 70 and lower by ten until happy.
Rear horn sensitivity 60%.(lower by 10 if required but remember Ka is affected too)
Rear K Mute only if necessary
K Filter On
TSF On
MRCD On as last resort or for other Mazdas
Quiet Ride 30 mph
Quiet Ride 1 beep: 1 or off
K Block 1 & 2 weak

Thanks for digging into this for the community, when you don't even own the BSM beast!

I've been very pleased with my CX-5, and think it's an excellent value for the money.

Well I stepped into the do-do when I stumbled across the MRCD trick.
Anything we learn helps us all out.
Any CX-5 owners here can certainly help out the rest of them with insights into their experiences.

I own the R3 and R7 and was wondering if anyone has done any testing with MRCD ON with the Mazdas. Is this anomaly something that was only discovered with the R7s?

I have a 2021 CX5 and have about 2 hrs driving with the R7 with version 135. It works well, positioned on the windshield. I don’t drive much as full time WFH, but I drive in MA so half the local PD run K band

advanced
Rear balance 70%
MRCD on
TSF on

I think I had KBlock on but may need to change to weak

on occasion I received rear K 24.123 and fairly certain they came from my car

But this is light years quieter than my V1 Gen1

What % K do you have Advanced set to?

K is set to 100%
Use Highway mode when you want 100%.
On Advanced set to 50% or so, to reduce your false alerts in the urban areas.
You can easily toggle from Highway, Advanced, City modes with a long press of the menu button, so you don't have to enter the menu.
Once the long press changes the mode you can quickly cycle through all 3 with quick button pressed.
Highway:100%
Advanced:50%
City:18%
R7 has excellent K range on all three modes.

Appreciate you setting up this K Falsers Anonymous Meeting @DC Fluid . I'll be testing out the settings you recommended.

As discussed in the other thread

Currently falsing occasionally with the following (@Vortex preferred) settings:
Advanced
K 70%
Rear 70%
K Narrow
K Filter On
Rear K Mute On
TSF On
MRCD On
K Block 1 & 2 weak
K POP Off

I'm running the rest of his config as well, these just seem to be the relevant settings I'll want to tinker with. I assume the preference is to reduce K prior to dropping the rear antenna sensitivity as it effects all bands?

From what I've seen from others, you're only one 10% drop on either K sensitivity or rear horn.
Only you can decide priority, but even 60% is hella long range on Ka out the rear.

Ah ok, so you're saying I probably only need to drop one or the other down to 60% and I should be set. I'll give it a shot and report back.

That's about where others reported back earlier, pre-135.

Knocked K to 60% and it was still falsing in the garage with the door and rear gate open, will need to do more testing.

BAD TEST environment.

In a garage or near solid objects is a bad place to test it as signals bounce back at you.
Evaluate on a drive, see if alone on the road is quiet.
If you get signals when cars come close behind you, then reduce rear horn% a bit, as that indicates your BSM bouncing back to you.

That was my thinking as well, bad test environmen. The other day at 70%/70% I think it was bouncing off a guard rail a lane or two to my left. Zero other vehicles on the road.

I still get Mazda BSMs with FW 1.54 and my R1. Expect the same with the R3. I never had BSMs with 1.37. Before rolling back to 1.37 I will try FW 1.50. Overall I get more BSMs with 1.54 compared to 1.37 especially GM vehicles. However, I do get fewer Honda BSMs with 1.54. All the Honda/Acura BSMs I get are in the 24.16X range.
