...set up the mic/voice recognition? Do I need OnStar for that? I have a 2019 LT, just got it at the end of last year & never thought about setting it up until now. My iPhone connects with ease but when it comes to using Siri or even completing a phone call, it will not pick up my voice. If there are steps I'm missing to set this up I'd really appreciate it!
Edit: I'm able to get Siri to work, though when I place a call the person on the other end cannot hear me, nor does the car's voice system work at all for me.
