I found that if you put the car in reverse and begin backing up right away (like I normally do) the dumb warning screen stays on for so long it is ridiculous and unsafe. However, if you shift into reverse and hesitate a moment before actually backing up, the camera will come on over the warning screen.My update went smoothly, generally like the update. What I don't like is on the previous version when I started the vehicle and put it in reverse the rear camera would instantly come on . Now it doesn't and I have to wait way too long for it to come on.
In the older version, whenever you were in reverse, the camera was always on regardless of the warning screen. I don't know why they would make such a change, but this seems to be the behavior in the latest version.
