I'd have to admit when I first got my Focus ST, I hated the navigation unit. I couldn't stand the MyFord Touch system. It was very, very, painfully slow and locked up about 15% of the time. There was a major update released at the beginning of this month that fixed all the issues. What a difference. I think Ford and Microsoft finally worked out most of the bugs. The system has worked great over the past few weeks. No more lock ups, very fast when changing screens, and it recognizes voice commands much better.
