Bluetooth as Phone Call
I have not found this option in the iOS version of the app.
This means Bluetooth navigation instructions and alerts are not played and the driver never heard then.
I have switched the audio output to “iPhone” but this setting does not stick/save between application uses. It has to be fine every time (not so with Google Maps or Waze).
Therefore, it is difficult to get TTGo to announce navigation instructions on the iPhone itself or over Bluetooth.
This kind of makes the app kind of useless as a navigation app.
Am I missing something or a setting to either have the audio always routed through the iPhone itself or payed over Bluetooth?
