I was on the way to work today and all of a sudden I started hearing this very strange popping noise coming from the dash area. Sounds like it is coming from the rear center of the dash and I don't really know how to describe it. It kinda sounds like an arcing but I can't see or smell anything electrical but it is pretty loud. It doesn't do it sitting still, more when you hit a bump, or braking. It does not sound like anything in the suspension at all, definitely the dash area. Any ideas, I have never heard anything like it before in a car. Recently installed the bluetooth about a week ago, it works perfectly, so I don't think it has anything to do with it. I turned the radio off, AC off, still make the sound. Any ideas, I will call the dealership in the morning.<p>Another question, does the bluetooth play through the center speaker or just the side door speakers? I do not hear it through the center speaker but the popping sound seems to be coming from around that area but still does it with the radio off and it does not sound like it is coming from the speaker itself.
