So I have noticed, especially when the navigation mini map is up, that my instrument display get very slow to refresh. As well steering wheel controls become very unresponsive when the screen is bogged down. If I stop navigation it immediately gets better otherwise it will waffle between being normal and up to 3 seconds behind. Last time I took the car in for service I asked they look at it, but they said it all tested out to specification. There are some threads about this issue, but on much older firmware. So I am curious if anyone else has these issues or if my display is just not quite right.
