Upgrade 2004 W220 Nav Navigation DVD .... Best options?
What are the best options for upgrading a W220 Nav DVD? I have a 2004 and the NAV DVD is still the original 2004 disk.
Is the dealer the best option?
I also read in some thread that upgrading the DVD changed something in the software and some functions / mods didn't work. Can anyone confirm?
What's the latest disk?
