The latest FW load for Escort 360c program might be available for the GT360. This does have MRXX detection. The last test of this by another CA based owner of a GT360 showed decent range against MRCD. still had some inconsistent reports. My 360c and 360 will pick up fixed MRTC speed cams. Enough to get a warning In time for quick action.
My GT360 I have, has not been upgraded. It works so well, left it on original FW. The range on Ka and K is better than the two 360c and 360 devices I have. Plus the BSM filtering is better. I do not want to fool with a good thing by upgrading to new FW.
I have the Cobra DualPro 360 which was the first Belscort product to get the MRCD firmware (before the Escort ones) - I don't think range or anything else has changed in any way, it's just that MRCD doesn't seem to bring much to it.
I see it as a "...Bring it to the noisyness levels of the others..." option, for anyone who thinks it's too quiet and wants all the BSM falses of the Escort big brothers (because it DOES bring more falses)
I had hopes for it to help me in New York City, but turns out here most of the traps are mrcT, not D, and it flies past them (the known ones) mute as a carp.
