how to reset display on blaupunk Bologna C50, not showing

Answer
If you install Adobe Reader, you can view the manual for it here:

The display may just be damaged or bad.
If the unit has a bad display it would probably be more cost effective to replace the headunit.
Obviously, check all of the fuses and try Blaupunkts' website for more support.

Good luck.
