Ah, now I see.. nope, FOTRS doesn't use these heading indicators at all, since there was no way anyone could know where a contact was going until you found them a few times and calculated the course between the findings. Part of overall realism. I believe TMO has this, too? Not sure though.
These 'updates' you enable or disable are the fact that you enable or disable the standing order to the nav officer to keep the map updated and track positions of the enemy for you after a contact is found for the first time. If you turn this off, you have no way of telling how fast an enemy is moving and where he's going, since its symbol will stick to its location and not go anywhere anymore until you actually see it.
When you see it, you can easily guess its course and speed, provided you are experienced in this guessing part.
As I see it, noone would be stupid enough to tell their men to deliberately forget about keeping track of radar/sonar findings, so I keep this on to calculate speed and course using my map tools before I even try to get visual contact.
Sorry, your first post was a bit confusing, thought you ment the contacts that are placed on your map via info from HQ (Contact reports).
