Click install, turn the car off, lock, and walk away for a while. It installs fine. This update doesn't fix the bongs by the way, or change any software numbers etc.. as it's not for the infotainment unit.
You'll want 1941 for that, which isn't OTA at the moment. No idea when it will be. You can install manually if you're brave, or chance asking your local VW if they've got it available.
