Installed non nav sync in a nav enabled sync

Based on the log you provided, you should still have nav.
There’s no “NAV/NONAV” specific Sync3 package, they are both the same, map packages is what makes the difference.

Again, based on the log you provided, no need for that since you had maps installed.

That’s strange, did it work before?.
Have you tried unparing the devices, making Sync3 forget about the phone (and viceversa)?. Also, try a master reset.

EDIT: also keep this warning in mind, since I missed mentioning it:
