Since that day when the stereo freaked out or it freaked me out, it's been working fine. Do you think it rebooted itself when I turned it off, and then actually turned off the ignition? Is it just a freak occurance, or do I need to contemplate trying to get help from the dealer? The problem will be trying to instantly take it there when the piercing noise is happening.... otherwise, they will assume I'm another "crazy" client! Of course that noise could send you there but quick! lj
