It's not uncommon for the bulbs to blow in the display,try shining a torch into the screen and seeing if the LCD part is still working.
As for the head unit,there should be a fuse in the back of the unit or in one of the power feeds,have a look at these and see if they are OK.
I'd rather push my Alfa than drive a BMW....
