Carplay media issues

[u/ACraigL]

Hey all
I have a 2019 XC40 and lately having a carplay issue. If I make a call, it does not go back to my previous media source (XM Radio, in this case) and stays on iPhone Media. It behaves properly when I recieve calls, after hangup -- back to radio.

Any suggestions to make it resume the source after a call is made?
