I had my car tinted with a 3M tint film. I was told it's non metallic or something so it shouldn't interfere with radio signals but my FM radio's signal would disappear or have static at times. This wasn't going on before I had my tint on. Is the antenna on the windows of the car? I'm not too worried since I have XM radio anyway and the XM antenna is on the rooftop therefore there is no interference. Just curious.
