BTW I just had my September 2018 build P3D+ upgraded to HW 3.0 Thursday. Dropped car off in the morning, ready end of day. They do warn you that they sometimes need to do a full vehicle reset (lose all settings). Mine went fine. You do lose Bluetooth settings to your phones (but not the phone-as-key settings), and also lose WiFi passwords. Some Nav and Autopilot settings revert to defaults and need to be reselected. FWIW my camera calibration took maybe 10-15 minutes on the highway. All good.
