We'll I don't have this problem any more since my x50 got jacked, but thought I would mention it since it did confuse me slightly.
I was driving the girls car around the other day (1993 Mirage Coupe). I just installed a new horn into it, electric style from Schucks. I noticed that when beeping the horn it set of a Laser alert from the x50. I took me a while to figure out what was going on, I kept looking around for cops everywhere (she hadn't had a horn for years so I was stoked to beep it at everything).
So I figgured that her horn made some sort of interferance. Well my buddies 2002 Jetta did the exact same thing, honk the horn, Laser alert. My 1997 Neon did not set it off.
Has anyone else ever had a similar problem?
