SYNC worked well for me for 5 years on my Fiesta, though I did have to reset it twice during that time. No problems with SYNC yet on the B Max.
I use voice conteols for the phone always and occasionally for the radio and USB stick. I never use CD at all.
When it says SYNC file, I think it is asking you to sync an app on your phone. Be aware that there are only 5 or 6 apps which will sync with the Ford system, though I did find a weather app synched, much to my surprise.
The only apps worth syncing are the Ford app and maybe spotify if you have unlimited data on your phone. If I rwmember correctly, there was also a mapping app that would sync.
I just dont use any apps that sync as that aspect of the system is atill in development and seems of litrle use.
