I currently have a V1 and Passport 8500/X2 and have been using a radar detector since the Eighties. I am considering buying a Cadillac Escalade, but just found out that it, like an increasing number of luxury cars, has blind zone radar.
IMO, this will be the death of the radar detector unless Bell or Valentine come up with a way to filter them - which seems pretty unlikely. The luxury features of today inevitably become standard equipment on mid-priced cars in a few years.
One thing that I don't think anyone here has considered is how do these new radar systems affect radar detector detectors in places like Virginia?
I am not sure what I am going to do, because I have to tow a boat, and this is the perfect vehicle.
By the way, I've lurked here for about eighteen months - its a great source information.
