I suspect that you have configured the Chart application's motion mode (PRESENTATION->CHART MODE AND ORIENTATION->MOTION MODE) to a setting other than Relative Motion. It is recommended that this setting be re-configured to Relative Motion mode (RM).
followed this recommendation but had to change page set to do it. I was using a custom page set. had to change to chart/radar/sonar set to make change. now chart and radar are set in RM. However I established two split screens, chart/sonar and chart/radar. in both cases chart is in auto range and cursor will not follow ship. these charts it will not allow me to move from AR to RM. radar screen is in RM
It is recommended that you ensure that the Chart view is configured to 2D in any of the affected Chart page/panes and then configure the Chart Synch feature to OFF within each of the MFD's Chart application pages/panes prior to changing the motion mode.
