I'm using a Samsung Galaxy Fold 6.
I've started riding a motorcycle and bought a Sena SLR3 headset.
But I'm facing an issue... If I listen to the radio in the headset from a source SLR3 , it ignores directions from Google Maps via Bluetooth from phone.
However, if I turn off all sound sources and leave only the connection to the phone, it plays the directions normally.
The headset also handles regular phone calls normally in both radio mode and standby.

I've enabled all the functions in the headset's setup application, but nothing helps. Bluetooth multitasking and Audio Overlay don't work either.

What else can I try?
