Hi FrameXX, thanks for the assistance in getting this sorted. Took a bit of searching to actually find where the "Send Intent" instruction was hiding, but all working well now.
Wrote a simple macro to automate launch of VLC media player when phone connects by BT to my cars infotainment system:
(T) Device Connected (Polestar PS2)
(A) Launch VLC, wait 20 seconds, Media Play
(C) None
It runs as far as launching VLC, but fails to actually play.
For Media Control Type there...
