So I just installed carplay on my 4000-next this morning. SWC controls work only for volume up and down while in carplay, previous and next does not work. Mode looks like it switches background audio input so I can get radio running in the background of carplay?

Anyone else having similar issues? Next and Previous work correctly outside of carplay.

I had this problem at first, also. Try restarting your iPhone and your car.

I only tried the voice recognition button, which worked the same as before - long press and Siri came up. I am subscribing to keep track of the info coming in.

My phone answer and end buttons didn't work, but they are working now. I have a Maestro SW for the wheel/head unit connection.

Yea I'm using aswc-1, I'll update later today when I get to test again. The mode thing is odd though, switching audio input in the background of carplay. I'll experiment more and will report back.
