Excellent range/warning time (unless they use instant-on or laser-nothing can save you then).
Arrows tell you if the signal is coming from ahead or behind, so you know to look ahead of you or in your rear-view mirror.
Bogey counter tells you how many signals are detected. (For example, if it says two, and you see one, watch out, there may be another one down the road.)
It blows away the competition in every radar detector comparison I've seen.
what about the feature on the other one that has a gps system in it with preprogramed sites like where they have camera's at lights etc. and learns what is false and what is new.
