My radar detector does not work any more in the new A8, It has dual pane glass that reflects 99% of uv rays. I wonder if that means radar and laser also? Is that a similar wave lenght? Any one had any luck with remote mounted detectors in the grill? I have been told it is speed limited to 130 mph due to the tires, like I did not pay enough to have z rated tires. Pat O'Malley
