Bluetooth speaker support

Is it possible to connect the head unit to an external Bluetooth speaker and have it play out of both the car speakers and the Bluetooth speaker? That would be game changing. Our minivan doesn't have rear speakers so this would solve that problem.

Finkalicious that would be undesirable anyway. There would be slight delay with Bluetooth audio. You'd hear reverb in the rear speakers. Overall, not a good idea to mix direct connection and Bluetooth connection.

Even if Bluetooth output is implemented, it is an either/or situation. It is not possible to output both via the cable and Bluetooth at the same time.
Therefore, your idea is not feasible. You should connect the speakers to the rear seats via the cable.

So I currently do this from a Samsung fold to output to the dudu radio and the Bluetooth speaker with no delay.

As for the possibility of having the output be both Bluetooth and built in speakers, I know it's possible as I do that with my home audio, but not sure how difficult it would be to implement.

Which connection do I use to output wired to radio in the rear? I could make that work for now.
