Love my Bolt. Really do. I continue to have bluetooth flakiness. I have an iPhone 7 with all the updates. My Bolt is a late December '16 build, so I have one of the Bolts where I can remove the fuse and eliminate the low speed buzzer...but that is another story.
My head unit is usually OK, but often will drop the bluetooth connection to the phone, and then immediately resume it. Also, intermittently when I initiate a call from the touch screen it will start, and then crash and reboot the head unit. Very annoying. There is a TSB on that, so I took the car into Chevy in March, and they did the software update and presumably the firmware update. Problem persists. So, I took it back yesterday to make sure they had done the firmware. They had. So, no change. They gave me a form to fill out, and I can take the car back to have them talk with the technical support team, but I think I will pass. I doubt this is a problem with my particular head unit, and is likely a software/firmware issue for all the head units.
For those of you who experienced this, did the firmware update solve your problems? Thoughts here?
