Is it the best update currently available from Ford? Yes. Is it perfect? No.
Since updating, I've seen the system change song tracks mid song without me touching the screen, steering wheel controls or phone... Its done it several times but I haven't been in the car long enough to fully troubleshoot it yet. Someone else posted this issue on another thread somewhere too...
Do a master reset. I had those exact issues and a reset seems to have fixed it for me.
