Just as the title says, I now have no radio, door chime, or navigation in my 05 545i. when I start the car a SOS with an arrow message is displayed. any ideas?

well i figured it out....there was 1/4" of water in the bottom of my trunk from a leaky cooler this past weekend and it fried my control module the smaller green one and the pdc one both appear to be ok. how much am i looking to be raped by my dealer? Or is this an easy buy a new one, plug and play and be fixed?

let it dry out. disconnect battery and take the modules out, put it in freezer overnight, and let it sit for another day and see if that works.

module is definately fried. should i be able to plug and play with a new one or do i need to check fuses also?

I have read that a few members have just replaced the MPM without coding. However, I do see MPM initiation/activate in INPA, so it might need to be appropriately activated.
