2000 BMW 740il - Water got into dashboard electronics - not working

Hello, I have a 2000 BMW 740il and i had a broken windshield. When it rained, water got in through the cracks and into my dash panel and the following stopped working:

Navigation
Power Windows
Power Seats
Radio
Instrument cluster


The car still runs and drives. Any ideas of what could be the problem?

Thank you
