So far, great. It would usually light up like a Xmas tree when reversing and steering was on full lock.
Tried it a few times, and not a single error message.
Not sure about the responsiveness of the screen being quicker, I wouldn't say I noticed anything different there. But then again, I never really noticed the responsiveness as being an issue in the past.
But, so far so good.
