Good day everyone!

I just bought a 320d 1999 sedan with the smaller screen tv monitor like in this pic:


Now, the thing that confuses me is that I got the CD Navigation system in my trunk which is like this one:



...but in the menu on my monitor there is no option for a GPS navigation:



Can someone help me out with this? Is it that my monitor does not support GPS navigation or am I missing something? Also, I don't know if the system is MK1 or MK2 cause when I go to settings I don't have any numbers showing me the type of system I have. Is it possible to upgrade my system and if it is, can anyone pls post a link for of the update for my system?

Thank you in advance!
