Hello everyone,
The OS on my MKIII is currently 3-1/41. I understand that the last OS update available for the MKIII unit is 3-1/63. What are the changes if I decide to update to 3-1/63, will there be any cosmetic changes, or just bug fixes? Any info will be greatly appreciated.

If I do decide to upgrade, I read that the OS update disks at the dealership are only $7.99 which I find hard to believe. Can anyone confirm this?
