I was driving home on the freeway last night and i got a k band warning a few seconds before getting a false x band in the same place i always do. my question is if the rx65 is hit with 2 or 3 diffrent bands which will it pick up? i went from a k with a signal strength of 4 bars to an x-band with 1 bar. also what is autoscan? is it more sensitive then highway?
