Just a thought.
I have the Hi-fi system. For me, you can hear the static noise after opening the door with the radio off, in the background when the radio is on, and a few minutes after the ignition is turned off.

I'm considering upgrading my amp and seeing if that fixes the issue, but I'm guessing that since the TSB describes exactly what I'm experiencing, I'm guessing I'll have to replace the head unit.
