Just wanted to share my experience in installing a Radar Detector in my 2020 SLT as there is sparse information on the passenger side fuse block in this model.

I recently purchased an ESCORT Redline 360c radar/laser detector. I originally suction mounted it to the windshield, up next to the rearview mirror, driver side for initial testing. I found this position adequate but it ended up blocking the sun visor from fully rotating forward. I ended up purchasing a BlendMount aluminum bracket to mount the detector to the under side of the mirror. I prefer the position as it mounts right under the rearview mirror and is out of the way of the sun visor. The only caveat with this bracket/mounting solution is that it moves with the mirror. I cannot get the detector to point directly straight through the windshield. The angled offset is not much but for the price of the bracket, I should be able to counter adjust in the Y axis to straighten it out. Oh well, it looks good without a performance hit.

To power the detector, I installed a remote power cord down to passenger side fuse block with an Add-A-Circuit plugged into the fuse block for power (did not want to crimp on to a wire). Initially, I could not find a fuse that was switched during Vehicle Power On/Off (GM calls this Retained Accessory Power Relay"), and my research did not turn up anything as well. After testing many fuse positions in this panel without any luck, I finally found the "one and only" fuse that works.
I have also confirmed this on the schematics now that I have them.

The only fuse that is switched on vehicle start in the passenger side fuse block is Fuse #24 "USB charger/Wireless charging"

Hope this helps.

I have the Redline 360c too. One other option is to use a Blendmount and Mirrortap. It is really simple to install.

Hmmmm, I've always found it easier to just obey the speed limits. Been driving 50+ years and never had a speeding ticket.

No need to spend money on something that may or may not work.

Thanks for the tip
I looked into the "MirrorTap" but don't have the powered Rear Camera Mirror option and didn't want to bother with disassembling that ceiling cluster looking for a plug to tap. Removing the A pillar panel and vent panel was pretty easy to route the wire down.

My daily drive is the Bishop Ford / Dan Ryan on the Southside of Chicago where there is no speed limit!!!
The detector also has Redlight and Speed Camera notification which has saved me a $$$ in Chicago.
