Hi everyone, I'm quite new to the x50 but im just a little confused on the mute button. While driving down the road, I experienced K-band while driving. Im pretty positive it was coming from the sliding doors. It always happens when I pass by the store. But I was wondering what the mute button does? Does it just mute for that specific time until the radar dies down? Sorry, just conffused on the mute thing. And I was wondering what setting do you recommend to put your x50 on? Radar roy recommends highway...but I was wondering maybe I could have yalls input. Thanks everyone!
