Nav disc upgrade lead to blank screen :/
I decided to insert the original back in and now have the same problem with that as well. Any ideas on what's going on?
my car is a 03' and imported to HK from the UK.
it has the sound system with tape cassete+CD+ CD changer and navigation of course.
problem is that when i turn on NAV it ask me to insert navigation CD (which i dont have).
from what i understand since my car is imported than Mercedes Hong Kong cannot activate my NAV system, however, is there a way i can still make my NAV work?
i really want it to work.
