I'm new here. Read the Nav forum carefully, but couldn't find reffernec to Z4. I know this is X3 world, but Z4 still a BMW .

I have 2003 Z4 Roadster with Navigation Profesional.
Will v29.1 upgrade work on it?

Another Q. If I want to have 2007 map. Which map version I need to download? The high version will not work?

Thanks for help.
