@Will-Brooks YES, exactly!
If you don't turn on data synching when you first setup the X3 features 1 and 2 still work just fine. These features rely on the bluetooth connection with your phone, not the data synching link with Garmin Explore.
Don't establish a bluetooth connection manually between your phone and the X3. When you pair your Tread app with your X3 it will ask you if you want to establish the bluetooth connection. When you proceed the Tread app will pair your XT with your phone via bluetooth.
In your phone's bluetooth settings you will then see a connection to your X3 just as if you would have manually connected them without the Tread app, however since the Tread app initiated the connection it can send the verbal instructions from the X3 to whatever bluetooth headset that your phone is using, and it can enable your XT3 to get traffic and weather information as well.

I have a Cardo unit in my helmet connected to my iPhone directly. It is not directly connected to my XT3 and it works just as if it was. I was also pleasantly surprised during testing the if I use my Apple AirPods they work perfectly as well even though they're not paired with my XT3. The ONLY bluetooth connection to my XT from my phone is the one that the Tread app set up.
The bluetooth connection in the phone looks just like any other bluetooth connection, but since it was initiated by the Tread app somehow the app can reroute the XT3's voice output to the phone's connected headset, and also use the phones data for the XT3's weather and traffic. AWESOME FEATURES!
