It seems that k band gives me enough time to slow down, few police use it here. I drive 70mi to work 4 days a week, and my STI goes off as soon as im almost at the troopers using ka, anyone else have this problem? It was just sent out and calibrated with the volume adjustment in april. Im driving to Nc next week to the beach, I can put it on the windshield after leaveing Va right? To clarify I usually have it mounted under the tinted part of the windshield to the left of my rearview, I have gotten brave and mounted it in the middle but with no difference in performance.
