Why doesn't the voice output work properly over Bluetooth?

Are there issues with voice output via Bluetooth?

A possible cause is that we currently do not support all Bluetooth profiles and infotainment systems of different vehicles.

Android users:

On Android, there is a small workaround that we received from a user of NUNAV Navigation:
The user uses the app "Audio BT Plus".

It is important to note that you need to set the "Don't reset SCO" function in the advanced settings.
Please also select the two options "Autostart" and "Autostop" so that the start and stop are executed automatically.

We are working on supporting more Bluetooth profiles, but we ask for a little patience here.
