Just spoke with the dealer and GM is blaming the reverse camera being on is the trailer backfeeding power to some circuit.... I laughed. And they will not replace the head unit at this time to try and fix the Bluetooth issue, GM is blaming my phone (iPhone 7 Plus on AT&T). Funny how any other Bluetooth I've ever had this phone hooked to it has never done it.

What phone and provider do you guys have that have had this happen?

Are you using Apple Car Play for phone calls or the GM Bluetooth?

I have an iPhone 6s on AT&T. No problems other than the occasional glitch where my stereo restarts. Has happened twice in a year and 30k miles

Happened again this morning. I'll try and upload to YouTube and copy a link over here. Luckily the guy I was calling didn't answer and I left him a voicemail and had him send it to me so I could figure out what people hear on their end when it happens

Disconnect the battery for 15 minutes and reset everything. This will reset the radio and may correct your issues.

Yes, I passed that along to the dealer. They told me that's if the person on the other end can't hear the caller clearly, not the problems I am having. I dont know if they performed that update, I doubt it.
