Hello.
I got problem with that stuff. My unit it's Simrad Evo3 nss9, RM2.0 and no way to see shaded relief maps in unit. It's recognize those maps as flat raster. Where is mistake? RM or another update from Navico vault?
I found solution. It's software case. Older update 59.1.72 working very well with AT5 shaded relief. Present version dosn't recognize shaded relief data in my unit.
Hope, that next Simrad update will be allowed using those maps.
