Hi,
I have an isue when exporting my map project to AT5. To see Shaded relief layer I must switch off all vector layers on my HDS. But my unit has an option to switch off/on shaded relief from Map View window. Also some other interesting functions like changing colors for my color pallet from the unit for isobaths polygons and etc. But these functions are not active on my map.

P.s. all these functions works fine on exported social map from Navionics

You are probably confusing C-Map Genesis and Navionics. And yes, there are a few functions that work with Genesis-mapping that will not work with Reefmaster.
