Hey guys, so I just got a used BMW E92 328XI Coupe, from 07 with the 07 software. My problem is that whenever I turn on the Nav unit (or the car), the cursor moves fine and responsiveness is great, but most tabs are empty/blank.. What I mean is, most of my entire system's options come up as a little box, but there is nothing written in it. For example:

When I go to Navigation, it should say Navigate to, then Address, etc etc. But all it says at the top is NAVI, then it has two or three options where I can turn my cursor to, but those options don't say anything.

When I go to system information or w.e, it is all also blank. Again, for example:

The TPMS SIGN shows on the Nav system but there is not writing below it explaining to me the problem, just the symbol. Can anyone here help me out?
