2007 BMW 335i Base 6 Cyl 3.0L

Body & Interior

Loud noise, then all sound quit working - speakers groaning now w/ no volume control

I have a 2007 335i with Nav / iDrive - Just finished washing and detailing my car, and then it rained for about 2 hours heavily. Not sure if this is related or not. After it dried out, I dried off the car and took it for a drive - the stereo was on, and after driving maybe 300 ft, the stereo made a very loud squealing noise and stopped all sound.
No sound is working on the car now - no courtesy blings when you insert the key, no radio, etc. The system isn't muted, and there's an SOS call malfunction warning on the dash display.
It randomly starts groaning loudly through the speakers - cannot control the volume of it at all, and basically sounds like the car is possessed.
The iDrive controller was barely working - taking forever to switch between screens, and unresponsive half the time.
I just purchased this car a few weeks ago, and noticed that when I first got it and attempted to pair the bluetooth to my phone, the microphone wasn't working. People could talk but couldn't hear me
