How do I turn on Left and Right spoken voice navigation prompts on the Garmin Edge 850 DEVICE ONLY?

I just bought the Garmin Edge 850 and I'm trying to have voice navigation prompts talk on the Edge device only.

I've made sure I've selected 'Navigation Alerts' and put Audio output to 'Device'

But it's not working?

It's only works if I set the Audio Output to 'Phone', then I get the Left/Right voice navigation coming out of my phone. But I don't want that.

  • Looks to be working now.

    I have to shutdown and power on again which is strange:
