I installed the 2.0 unit on my '12 1600GT in 2012 and used it for four years with a H.A.R.D. installed in my helmet. Work as good as any other radar detector I've ever ridden with in a group ride. I'm usually leading the ride my my group so maybe that gives me a bit of advantage but it's always going off as soon as or before the other "top quality" brands used by my friends. The weather proof aspect of it combined with the ability to react to switched power makes it easy to tuck away in a covert location and never think about it again - it's always on and alerting me when it should be.
The 2.0 unit has the transmitter in it for the H.A.R.D. so another added benefit is that you only have to buy the receiver from Legal Speeding to be up and running with a helmet mounted LED warning display.
'12 K1600GT (gone but not forgotten)
'13 S1000RR (sold it to Allstate)
'14 KLR 650 New Edition (gone and thanks for the memories)
'16 R1200GS Triple Black (for all of it)
'16 KTM Super Duke 1290 R (for the inner hooligan in me)
'18 WR250R (for all of it...but slower)
