Today I got my Cobra XRS 9440 12 BAND Radar Detector with voice, and extreme range technology. I put it on and drove for about 1 hour with it! It did very good for the most part! Picked up some false readings around grocery stores with automatic doors, and security sensors! It went crazy when I passed the police station! It picked up cops in parking lots when I passed them! But I was wondering a few things! I passed a few cops at intersections and it never went off! Shouldnt it pick up the cops? Or will it not pick up moving ones! I was also wondering what all of the settings stood for and weither I should cut any of them off while others are running!
They are X, K, KA, V, S! I currently have all of them on! Am I supposed to?? ANd also what is better to drive with city, or highway! I am driving highways through the city mostly!
