You have multiple issues. Fortunately, most of them are easy. The two biggest things are that 1) You have a modified nav OS that you probably should get rid of (unless you know what it is and want it) and 2) You need to get the MKIV coded for your car...

This is a known issue. I am not sure why it doesn't happen to everyone. Anyway, give the solution in this post a try.

This is most likely due to the combination of a modified navigation OS and coding for the language preferences. The language on the instrument cluster is driven by the language selected on the navigation display. My hunch is that someone modified the language files so the setting is not the same as the displayed language.
This requires a two-part solution. First, you need to get an official BMW OS update CD and get your OS to a an official 4-1/00. Second you need to get the nav computer coded so that it has your language preferences loaded.

This is a coding thing. See above-- you need to get the nav computer coded for your car.

You have a modified nav OS. Unless you know what is modified and want this, I would get rid of it. Yes, you should learn how to install an OS update, but you will also want to do the nav coding in combination.
NavCoder will fix the coding issues above. That will let you set the proper language preferences and load those into the nav computer. Also, it will let you fix the date thing. (And, I bet your INFO and SELECT buttons don't work either. See the following post. NavCoder will also help you fix that.)
Restoring INFO & SELECT is easy; white line may be a screen defect
NavTweak is one tool that people use to generate modified OS images. You can use that in the future to tailor it to your liking, but it will not help you fix anything.
