X3 3.0d 2004 software upgrades
 

Hi,

I am new to this forum, thank you for letting me join.
I am also new to the BMW X3 world. I just bought myself a 2004 3.0d with most of the original equipment one can get, including navigation.
I don't think my car have had any software upgrades in many many years. What can I achieve when upgrading it?

My Navi is running 4.1. Is it possible to upgrade it, and will I then get any new features?
