Hello.
I bought a 1995 E38 a few days ago with the old 4:3 monitor and a mk1 navi.
In the menu it says I have 1-1/72 software version.... but....

The option for 'GPS navigation' is not itself on the menu. I see only: Phone, Auxilliary.., TV, OBC, Monitor Off, Settings, Code.

Does anyone have any idea why the 'GPS Navigation' option is missing, despite the software version being visible??
