I checked the Rino last night. It appears that you do have to be moving to get the compass to work reliably. Several times I tried navigating, stopping, and doing a 180 degree turn. The compass ring moved with me. I began moving again and it corrected.

I quote from the manual (horrors!): "The Compass Ring does not function as a magnetic compass when you are stationary. Although the bearing to a point will be correct, you must be moving in order for the compass functions to work properly."

Maybe it should work as a map compass but mine does not--at least not reliably. I've only got one year of hunting with it under my belt though so I'm sure there are plenty of things I don't know about it yet.
