Hi,
I've recently bought E46 328i originally from Japan.
I've found that it has DVD-based MK4 navigation system. Must be upgraded by owner in Japan recently. Am I right? I thought MK4 was available well after 1999.
By reading some articles written by Jochen, it seems that I need to change something (sorry. To be honest, I could not fully understand what Jochen wrote. I don't know much about cars. :-(
If I upgrade my navigation system so I can use in NZ, Do I need to get a new MK4 unit or can I keep my old one.
What do I need? Just a new DVD?
Thanks.
