Static noise, no separate amp
 

2002 4.4l stereo-nav-widescreen-tv-handsfree is installed.

Hi, I got serious static noise through my speakers, even after I switch the engine off, so I had to disconnect the speakers to be able to drive.
I'm trying to figure out where it comes from and been reading loads in this forum and others, it seems to be a common problem that's mainly caused because of water in the amplifier. As you can see there's no separate amp in the left side of the booth. #1

I then looked at all the boxes that there were in the booth to figure out what they could be. I put them on pictures in case anybody else is trying to figure out the same problem.
#2: Transmitter-receiver for Motorola.
#3: hands free phone dual band compensator 6907520)

#4 is the Rmfd video module, high, uncoded, just a plastic box with nothing on it but runs with a cable to widescreen module #5

I don't know what #6,7,8 are or where the problem could be.

BMW charges a fortune to put it on the computer as usual.

Any help or guidance is appreciated.
