Steering Wheel Control (SRC) Siri Trigger
I've been trying to map my Steering Wheel Control but I can't find one that triggers Siri in CarLink/CarPlay.

When I use the microphone button, It only triggers Google Assistant.

I can't find the Siri Button. How do I fix this? Is there a button to trigger Siri?

Also, what do the numbers across the top mean? (215) (215) (251) (251) (254) (254)

Also, what does the "K" mean next to the Phone-Talk and Phone-Hangup buttons?
