Reverse lights,alarm lights &signal indicator doesn't work

I am having a problem with my 97 750IL. The reverse lights do not work, the lights dont flash when I activate or deactivate the alarm, the dome light doesn't come on when i turn the key off and the turn signal indicator doesn't work. My back up camera also doesn't do anything at all, like when you put it in reverse the navigation screen doesn't change.
I have checked alll bulbs connectiois and I just can't seem to figure it out. Does anyone know what the problem could be?
Please let me know
Thank You
p.s
My check control system is also not working, I think that there is one little thing causing all my problems.
I went to BMW Tis website and there is nothing there that could possibly help me. Has anyone had any kind of problems similar to mine? Please let me know.
Thank You

Does anyone know where the flasher is located on this car?
