Well it finally happened.
I've had my V1 about 1 month and two weeks and today was the first "JOut" that I've read you all talking about. I assume it was from another detector because I rolled up to a red light, and a car approached on my right to make a right on red.
Just as they rolled up I got a quick Ka alert (1 blip) the a "J" as they turned right.
I tried to see a detector in the car but no such luck. It's wierd because I've sat at lights (and passed) several cars with detectors on the dash in the past and this is the first "J" I've received.
I run my V1 with POP off, and X off.
