Hi folks,
First of all, thank you so very much for such awesome info on our NAV systems, y'all have been huge wealth of information and for that i'm very appreciative.
I have a small issue. My setup is follows:
2006 M3 with MKIV Factory NAV.
Car came with ver 4-1/60.
I upgraded to V31 (4-1/00).

I'm able to get into perspective view, but when i do, i have no street names showing up.

Do I need a new map disc for this info, or should i have done an incremental upgrade to v31 from V26?

Would love to get some input from you folks on this.
Thanks!

Jake
