The vnomics monitors are attached to the fuse access plate which is below the cup holder and above the ash tray. This access plate is only held in place by two screws. The weight of the monitor cracked the area around the screws and the whole mess fell out of the dashboard. This happened twice before I gave up and set the monitor on top of the dashboard.To make matters worse, each time that the monitor fell the tractor bumped as if I had dropped a trailer onto the frame. I don't know whether the monitor connection had anything to do with the bump but it only happened the two times that the monitor fell. You might want to check the plate screws.
