Many people are saying that turn by turn alerts are not working. I just tried this a few hours ago on FW 12.22 and it worked for me. When starting a course, be sure to first select “more…”, then go into Route Settings and choose Guidance Alerts on.
Two problems however - the release notes for 12.22 state that these alerts are now on by default but that does not seem to be the case at least for courses created before the update.
Secondly I do not readily see a way to set route settings for navigation used in conjunction with PacePro.
