Also Chevy Trailblazers, my V1 goes nutz if I'm behind one and they start to brake. Something in the way the rear lights are on the Trailblazers, it sets off any detector. There was a big article on it somewhere, on how people with detectors had them go crazy if near a Trailblazer braking.Valentine is the BEST, others pale in comparison. BTW, on all Infiniti FX45, and others I am assuming, they have a lasar guided cruise control. YOUR V1 will go off like crazy and you'll think you just got busted by some State Trooper with laser. Don't fret, just look around for one of those vehicles.
