My thoughts after using it for a lot of holidays journeys:
I think, overall it's an improvement. The very lightest of customisations in pinning apps, the new font, the blind spot cameras are all very useful adiditons, especially the latter but, it's clearly not a finished product yet:
Some critical functions such as fog lights take an extra press. The menus are too "deep" and mean too much time pressing the screen and not watching the road
Should be an option to retain the "status bar" at the top that shows connectivity and software update notifications
Cards for the trip computer and tyre pressure gauge (certainly the former) must return
Though useful, the rear view cameras would probably be more useful if you didn't obscure them with your left (or right for the RoW) hand in the normal driving position
I think, though, it has more potential then the previous version. I found it poor. It was a very basic interface. This one is more complex which of course takes some getting used to but it does mean it's a more useful piece of software
