Driving down the road, figured I'd play around with my vehicle dynamics, so I switch the screen and there is nothing there. All I have is the default blue background, otherwise the screen is blank. Has anyone else experienced this, and if so, what's needed to fix the issue. I went into the system options, I see my vehicle speed is being read, I have not touched anything on this unit since I installed it over a year ago. Any help would be appreciated.

What version of the software are you running? Perhaps upgrading the N3 software will solve your issue...
