I drive through a parking lot daily basis that has MANY K band door sensors(I always max out my bogey counter to 9). I've set up the option to Unmute at 6. Does it do it's job to unmute @ 6? Not always, sometimes it works other times it sounds alerts and I have to manually press the mute button, sometimes it sounds a bogey alert, other times it does not. Am I asking it too much to work as designed? or could it be defective? Should I do a video to show what I mean?
