I have the 800/900 expansion and I have the MFD set to side by side, compact display unchecked. When I press the ENG or SYS button the screen doesn't change. What am I missing? Thanks!Mike Brown

The ENG and SYS buttons are for the lower display. In the 2D panel right click on the MFD and then hit ENG and SYS. If you need further information, do a search. Lots of posts on this one.

Got it, thank you.Mike Brown
