I'm pretty new to radar detectors and I have a few questions. I already read through the stickys and I couldn't find the answer. Do radar detectors only alert you when the officer is running his handheld radar gun, or does it also alert you as to when the in car radar is on? By the in car system, I mean the thing mounted on the windshield of their car, and it shows the speed readout on the screen. Sorry, I hope I'm making sense here...
Also, while I'm on the topic, does anyone live around Columbus, OH? Do you know what band of speed detection equipment the Columbus Police or Ohio state patrol uses?
