The laser shifters are plainly visible on the grill near the intercooler/radiator, while the radar receiver is behind a solid part of the bumper cover. Radar works great despite the low elevation compared to a high windshield mount. Laser shifters died years ago (bulging like bad capacitors, white crust seeping out). I only have front mounted stuff, although the main controller does have unused ports to add rear stuff, so yes you could say my particular setup is non-360.
I don't really mind losing the laser shifters. Jam detection is a ubiquitous feature of police units as I understand it, and I'd rather not poke that bear even if it's totally legal. The technique, though, is to cancel the jamming after just a few seconds during which you reduce your speed, such that ultimately you allow a good reading to overcome any suspicion of jamming. Some people like to automate the delayed cancellation, while others prefer to manually cancel. Interesting, but not for me.
