I had a last generation Passport 8500 which would give me false laser alerts every few minutes. I thought sure it was a problem with the detector, so I traded it in on a new 8500 X50. This morning I got two seemingly false laser alerts on that one, too. The only thing I can think of is that I have a small crack on my windshield and maybe it's refracting light into the detector? Or could it be a power issue? Would surges in power set off the laser alert?
