I was quite surprised that it's standard, and it was quite easy for us to avoid the 'Discover Pro' £1325 option.
The Discover Pro lets you show navigation maps on the dashboard and entertainment screen at the same time, and it's a bit bigger, but neither of these things bothered us.
The "gesture control" looks a bit naff. Not sure what the two knobs on the standard system do, but I like knobs... you can use them without looking.
