What are you guys using to enable steering wheel controls for the AppRadio 2? Specifically, I cannot get the Push-to-Talk button to bring up the voice dial prompt of the head unit. Everything else works but those two things and it is driving me nuts! I am currently using the Axxess AWSC interface.
I realize similar questions have been asked, but none were explicitly my question (at least the ones immediately available when searching), nor was an answer to my question provided in them.
