I have a 08...

When I power up my car, my Navigation screen will flash "BMW", then flash again with lines through the screen, then flash "BMW" again, then flash different lines through the screen. It will do this until the system powers off and then tries to do it again.

-Nav disc drive still runs the disc and will eject on demand
-*My phone still picks up the bluetooth and WILL connect to my phone
-*If I press Siri (iPhone) (connected to my car) will display on my phone that it can hear what i'm saying through my car bluetooth phone speaker
-I cannot pickup calls
-No music comes out
-I've already tried the volume/mute button, and hold both eject buttons for a reset, no luck

Does the nav monitor have anything to do with how my system is operating? This is my last option before I buy a used CCC unit.
