I borrowed a 2008 Mercury Mountaineer for a week to move and every time i put my v1 up against the windshield it's has a constant alert 1 bar K band. If I move the Valentine One away from the windshield it stops going nuts. If i look at the windshield very closely I see fine metal wires waving down the windshield in an "s" shape. I'm assuming it's for a front electronic defrost. I'm also assuming it creates a Faraday cage affect and reflects some harmonic frequency of the K band from the detector itself?
Has anyone heard of this before?
