I've got a FR 645 (non-music) and used to use Jaybird brand earbuds to listen to music from my phone when running. I would get the lap announcements through the earbuds. I've now switched to Jabra brand earbuds and changed nothing else, but don't get the audio prompts. I checked in Connect mobile app and audio prompts are still set to on. So, has anyone had this or similar experience and is there a work-around/fix?
