NavMap Uboat Compass Rose
 

In SH3 when you zoomed in close you would get a compass rose with 0 at the heading of the uboat and range circles out to 1500m. Is this possible in SH5? I'm playing WoS Mod and I don't see it at all when I zoom in or on the map tools.

There should be a small blue button at the top-right corner of your navmap (it will look similar to the "Return to Course" button). Click it and you'll get a bearing overlay on your boat. It's not perfect...it doesn't scale with the zoom level, so it's the same size at any zoom, but in a pinch it'll give you a direction. When in doubt though, U-Boot Course + Bearing = True Bearing (-360, if True Bearing is > 360)...that'll be more accurate for plotting purposes.

I don't see either of those, maybe because I am playing 100% realism with real navigation.

Yeah, that would do it. Having the bearing overlay would be a massive giveaway as to your true position.
