I just updated my 2019 non-HK head unit today. In the past I was able to use my phone as a hot spot by linking the head unit to my iPhone. Today, the head unit asked me to install the Aha app on my iPhone first. I installed the app on my phone and registered. Then I went back to head unit and clicked on "check for updates". At that point my iPhone Aha app showed a screen with Starlink on it. I clicked on that and the car started to download the update. It took about a couple minutes to completely download the files. The head unit then rebooted and showed an update progress screen as it went through the update progress. After about 5 minutes the head unit rebooted once again and the update was complete.
Don't bother using your house wifi to try and update. I have a mesh router and my car sits no more than 30 feet from one of the access points, and I've never been able to update via wifi even though I get a great signal from my mesh router to the car. Use your phone as the hotspot and it works great.
