The 9500ci (the built in) does not detect rear radar according to the literature. Is this correct? I would love to get the built in 9500ci, but the lack of rear detection is an issue. I have the Calibre K40 built in and the rear detection has been a godsend.

In my experience, a regular detector would not get a reading when the cop is behind you the way the V1 or K40 does. Or the widshield mount 9500.

It's all in the rate of change in the signal strength. First of all, when I detect a bogey, I SLOW DOWN...I don't decide whether or not to ignore my own radar detector and keep on speeding. I stay slow until the signal is gone.

You can always tell where the bogey is coming from: Slow rate of change, the bogey is behind you; fast rate of change, the bogey is in front of you. I'm only aware of one single pathological instance where the V1 arrows have any merit at all: when you pass one bogey going in the opposite direction, and there's another one a few hundred yards behind him. But other than that one pathological case, I've never heard another expample of the arrows providing any benefit that is otherwise unobtainable simply by being a smart and observant person.
