I'm pleased with my STi-R overall, have used it now about four months and its forward-Ka sensitivity is as advertised. It seems like a good tandem with the LI and V1, recognizing some say in some installs there may be some cross-interference. I can't see any deterioration in my V1 performance before/after, so I'm leaving it as is.
I did have to disable the STi's K-band, though, the intereference on those frequencies caused by my active cruise control weren't solved. But V1 is fine for me on K.
The one area I'm generally disappointed in the STi-R's sensitivity is Ka from the rear. It always is way late compared to the V1, and on occasion doesn't detect it at all, while the V1 will continue to monitor. Is this a known issue, is it possibly V1 effects on the STi, or what?
Thanks in advance for your thoughts.
