Had mine updated to 1940 yesterday. Dealer said this update has been out for about 10 days or so and they are getting in touch with owners to have them come in for the update. Apparently its aimed at fixing the random restart issue, so hopefully it works. I was having a intermittent restarts previously but no other issues, and actually I quite like how the infotainment system looks and works. No issues since this 1940 update, although still early days.
One question though - does anyone know if its possible to change the positioning of the 3 widgets on the home screen please? ie, i want to have navigation in the centre position but when i try to change this centre widget it doesnt give me the navigation option - it seems to only be possible to have it on the left pane/widget position.
