How-to: Update your Chevy Bolt firmware via USB so Android Auto and Google Assistant work beautifully

Google this week announced that it was putting Google Assistant on Android Auto which basically means that your Android phone is now a Google Home/Amazon Echo type of device in your car that you can talk to. This, as opposed to having to push the button on the steering wheel, is great for passengers who want to ruin my music vibe.
Unfortunately, my Chevy Bolt was on an older version of the firmware which apparently isn’t OTA upgradable and cut out Android Auto on my Google Pixel every few minutes. To properly test and use Google Assistant, I was going to need to get a firmware update. Off to the Chevy dealer, right?
