Just had an HW 3.0 upgrade done in Devon,PA on my 3P-. I inquired if upgrade available via the app. They advised they were ordering the part. It arrived quickly. This tells me they were constrained by replacement boards (a couple weeks ago).
They originally scheduled via Rangers but then changed to in house at Devon. Provided a loaner when dropped off and advised it would likely be overnight but they texted complete in 6 hours
I took my own pen & wore gloves and a mask in the loaner because "who knows". My SW data was preserved
You need to re-establish your WiFi at home so the large maps file can download, uncompress and install which took about an hour for my WiFi connection. It takes a bit to become available in your "Autopilot" settings. Some have done a reset (brake peddle, both buttons on wheel) to help it along but not sure that is advised.
So the HW 3.0 upgrades are indeed moving east. I suspect they are slowly being ramped up based on parts availability but will eventually as parts stock improves likely be pushed out rather than by request IMO.
