I have a problems with my 5-er few weeks now .When I live auto few days without start my batery drein out.I Found A Solution for that...take out a fuse for audio end navigation end then my battery stay intact.Im notice that my navigation screen have some strange blue color end font....On the Menu dont see anymore Navigation option.Im notice that navigation cd try to load disc few times end than disc get out....than get in again end that stops when I take fuse out.On the navigation screen (uper right corner)I dont see SW Number anymore!
I dont now what to do....tray to upgrade navigation sw (maybe this solve the problem)or take car to Bmw dealer?
Any suggestion is welcomed.Thanks in advance......
